stm32 usart receive timeout - timeout

I am trying to read informations from a external sensor by USART, using a Nucleo stm32wb board. The sensor is using a 9600 baud rate and I know that it is fonctionnal. My pin connections are also good.
Furthermore, I can see on my logic analyzer that data are always sent.
The problem is that I always got a receive timeout no matter what timeout using.
Here is my code :
int main(void)
{
/* USER CODE BEGIN 1 */
/* USER CODE END 1 */
/* MCU Configuration--------------------------------------------------------*/
/* Reset of all peripherals, Initializes the Flash interface and the Systick. */
HAL_Init();
/* USER CODE BEGIN Init */
/* USER CODE END Init */
/* Configure the system clock */
SystemClock_Config();
/* USER CODE BEGIN SysInit */
/* USER CODE END SysInit */
/* Initialize all configured peripherals */
MX_GPIO_Init();
MX_USART1_UART_Init();
HW_RTC_Init();
/* USER CODE BEGIN 2 */
int incomingBytes[100];
uint8_t d = 'a';
/* USER CODE END 2 */
/* Infinite loop */
/* USER CODE BEGIN WHILE */
while (1)
{
HAL_UART_Receive(&huart1, &d, 1, 1000);
if(d == 0x42){
incomingBytes[0] = d;
for(int i = 1;i<31;i++){
HAL_UART_Receive(&huart1, &d, 1, 1000);
incomingBytes[i] = d;
}
}
/* USER CODE END WHILE */
/* USER CODE BEGIN 3 */
}
/* USER CODE END 3 */
}
/**
* #brief USART1 Initialization Function
* #param None
* #retval None
*/
static void MX_USART1_UART_Init(void)
{
/* USER CODE BEGIN USART1_Init 0 */
/* USER CODE END USART1_Init 0 */
/* USER CODE BEGIN USART1_Init 1 */
/* USER CODE END USART1_Init 1 */
huart1.Instance = USART1;
huart1.Init.BaudRate = 9600;
huart1.Init.WordLength = UART_WORDLENGTH_8B;
huart1.Init.StopBits = UART_STOPBITS_1;
huart1.Init.Parity = UART_PARITY_NONE;
huart1.Init.Mode = UART_MODE_TX_RX;
huart1.Init.HwFlowCtl = UART_HWCONTROL_NONE;
huart1.Init.OverSampling = UART_OVERSAMPLING_16;
huart1.Init.OneBitSampling = UART_ONE_BIT_SAMPLE_DISABLE;
huart1.Init.ClockPrescaler = UART_PRESCALER_DIV1;
huart1.AdvancedInit.AdvFeatureInit = UART_ADVFEATURE_NO_INIT;
if (HAL_UART_Init(&huart1) != HAL_OK)
{
Error_Handler();
}
/* USER CODE BEGIN USART1_Init 2 */
/* USER CODE END USART1_Init 2 */
}
Any idea of what I could forgot?

Initializing LwIP causes RTOS to stop working

Good day
The goal:
I am trying to configure FreeRTOS and LwIP so that I can set up MQTT.
I am using a STM32-NucleoF429ZI development board
What I have done:
I am using CubeMX to generate project files and I am using Visual Studio and VisualGDB for compiling and debugging.
I have set up FreeRTOS for the dev board using CMSIS_V2 and Heap_4.
I have set up LwIP with: Static IP and MEM_SIZE of 1024*10
I have kept all standard pinout (i.e. I have note cleared pinouts) of nucleo board
Ive set up an "Ethernet" thread and I am blinking and LED on the ethernet thread and the default thread.
Other than that no other setting has been changed. I did not set the MPU because as far as I can tell, this MCU does not have it.
The problem:
If I comment out the line MX_LWIP_Init();, (which cubeMX puts into the default thread), then the board runs fine and both LED's on both threads blink forever as far as I have tested. However, as soon as I leave MX_LWIP_Init();, FreeRTOS gets stuck as shown in the picture.
This occurs anywhere from 30 seconds to many minutes after powering the board
Please excuse the picture, but it shows where exactly the program is when I pause it. If I resume the debugger and pause it again, it always pauses in the same place.
I have tried moving MX_LWIP_Init(); into main.c with the other init functions and also into the ethernet thread where it should belong. All produce the same error at some point.
I can ping the board once I add MX_LWIP_Init();

I am not sure the cause of this problem, but I have changed from FreeRTOS CMSIS_V2 to CMSIS_V1 and it resolved the issue. I dont know if there is a configuration in CMSIS_V2 that was wrong, or if there is an actual bug, but CMSIS_V1 and LwIP works great now.

I have a problem reading ADC with DMA on STM32 F767zi. When I look into the buffer, all I see are zeros, and I do not know why?

The size of my buffer is 4096 and I want to fill the buffer with the adc values that are read.
#define ADC_BUF_LEN 4096
uint16_t adc_buf[ADC_BUF_LEN];
I am using this function to start the reading process of the ADC using DMA
HAL_ADC_Start_DMA(&hadc2, (uint32_t*)adc_buf, ADC_BUF_LEN);
Here are my configurations for the ADC
hadc2.Instance = ADC2;
hadc2.Init.ClockPrescaler = ADC_CLOCK_SYNC_PCLK_DIV6;
hadc2.Init.Resolution = ADC_RESOLUTION_12B;
hadc2.Init.ScanConvMode = ADC_SCAN_DISABLE;
hadc2.Init.ContinuousConvMode = ENABLE;
hadc2.Init.DiscontinuousConvMode = DISABLE;
hadc2.Init.ExternalTrigConvEdge = ADC_EXTERNALTRIGCONVEDGE_NONE;
hadc2.Init.ExternalTrigConv = ADC_SOFTWARE_START;
hadc2.Init.DataAlign = ADC_DATAALIGN_RIGHT;
hadc2.Init.NbrOfConversion = 1;
hadc2.Init.DMAContinuousRequests = ENABLE;
hadc2.Init.EOCSelection = ADC_EOC_SINGLE_CONV;
if (HAL_ADC_Init(&hadc2) != HAL_OK)
{
Error_Handler();
}
This my DMA configuration
/**
* Enable DMA controller clock
*/
static void MX_DMA_Init(void)
{
/* DMA controller clock enable */
__HAL_RCC_DMA2_CLK_ENABLE();
/* DMA interrupt init */
/* DMA2_Stream2_IRQn interrupt configuration */
HAL_NVIC_SetPriority(DMA2_Stream2_IRQn, 0, 0);
HAL_NVIC_EnableIRQ(DMA2_Stream2_IRQn);
}
These are my interrupt functions. I set a toggle breakpoint on the first interrupt and when I debug, the LED does not turn on which suggests that the DMA isn't working?
/* USER CODE BEGIN 4 */
//Called when first half of buffer is filled
void HAL_ADC_ConvHalfCpltCallback(ADC_HandleTypeDef* hadc) {
//HAL_ADC_GetValue(&hadc2);
HAL_GPIO_WritePin(LD3_GPIO_Port, LD3_Pin, GPIO_PIN_SET);
}
//Called when buffer is completely filled
void HAL_ADC_ConvCpltCallback(ADC_HandleTypeDef* hadc){
HAL_GPIO_WritePin(LD3_GPIO_Port, LD3_Pin, GPIO_PIN_RESET);
}
I set the prescaled to be divided by 6 if this information helps.
Please give me some advice!
Thank you in advance.

Using both CAN1 & CAN2 both in STM32F446 properly?

I want to use both CAN1 and CAN2 for my application with 500kbps and 125kbps speeds respectively. I have initialized both of them as per my requirements using HAL. Where in Tx is implemented in polling and Rx in interrupts. CAN1 Tx and Rx working perfect. Coming to CAN2 Tx is working and Rx is not working. Interrupt itself is not firing up for CAN2 Rx (HAL_CAN_RxFifo0MsgPendingCallback is not being called). I've read in datasheet that SRAM sharing process is happening between 2 CANs. I'm unable to comprehend that. Is that an issue?
I'm attaching the code also. Please check and help!

I solved my problem. Got help from ST community. Please refer to the link below.
https://community.st.com/s/feed/0D53W00000RQCwgSAH?t=1608012202888
Problem was filter configuration for CAN1 and CAN2. There are 28 filter banks (0-27) split between CAN1 and CAN2. First half (0-13) for CAN1 and the rest for CAN2. So just make some changes in the code posted above -
CAN 1:
sFilterConfig.FilterBank = 0;
:
sFilterConfig.SlaveStartFilterBank = 14;
CAN2:
sFilterConfig.FilterBank = 14; // previously 0
:
sFilterConfig.SlaveStartFilterBank = 14; // previously 27
Thanks to Lundin for suggesting sync point. Use this website for CAN Bit time calculations for various chips -

STM32F411, FreeRTOS and CubeMX HardFault_Handler() after connecting to port

I need help with my project. I'm using Atollic TrueSTUDIO, CubeMX and FreeRTOS. I have project in which I recived data from ADC and I'm trying to send it by USB. Everything works fine until I open port at PC (I'm trying HTerm, RealTerm, etc), after that dubugging stops and HardFault_Handler() appears.
Here is my main.c (everything is generate by CubeMX for FreeRTOS:

void StartSendTask(void const * argument)
{
/* USER CODE BEGIN StartSendTask */
MX_USB_DEVICE_Init();
/* Infinite loop */
for(;;)
{
if( xQueueReceive(dataToSendHandle, sender, 10) ){
if( xSemaphoreTake( myBinarySem02Handle, ( TickType_t ) 10 ) )
{
counter4++;
HAL_GPIO_WritePin( LD2_GPIO_Port, LD2_Pin, !HAL_GPIO_ReadPin( LD2_GPIO_Port, LD2_Pin) );
volatile uint8_t send = CDC_Transmit_FS( sender, (length/8) );
xSemaphoreGive( myBinarySem02Handle );
}
}
}
/* USER CODE END StartSendTask */
}
/* USER CODE BEGIN Header_StartADCTask */
/**
* #brief Function implementing the recivedTask thread.
* #param argument: Not used
* #retval None
*/
/* USER CODE END Header_StartADCTask */
void StartADCTask(void const * argument)
{
/* USER CODE BEGIN StartADCTask */
/* Infinite loop */
for(;;)
{
if( xSemaphoreTake( myBinarySem01Handle, ( TickType_t ) 10 ) )
{
HAL_GPIO_WritePin( LD2_GPIO_Port, LD2_Pin, !HAL_GPIO_ReadPin( LD2_GPIO_Port, LD2_Pin) );
counter1++;
for( int i = 0 ; i < (length/4) ; i++ ){
HAL_ADC_Start_DMA( &hadc1, reciver, length);
}
if( xSemaphoreGive( myBinarySem01Handle ) == pdTRUE )
{
xQueueSend(recivedDataHandle, reciver, 10);
vTaskDelay(1);
}
}
}
/* USER CODE END StartADCTask */
}

/* Infinite loop */
for(;;)
{
if( xQueueReceive(recivedDataHandle, reciver, 10) ){
HAL_GPIO_WritePin( LD2_GPIO_Port, LD2_Pin, !HAL_GPIO_ReadPin( LD2_GPIO_Port, LD2_Pin) );
counter2++;
if( xSemaphoreTake( myBinarySem01Handle, ( TickType_t ) 10 ) )
{

{
volatile uint8_t counter = 0;
for( int i = 0; i < (length / (16 * 4)); i ++){
for( int j = 0; j < 16; j++){
prepared[counter] += reciver[i * 16 + j * 4 + counter];
prepared[counter + 1] += reciver[i * 16 + j * 4 + counter + 1];
prepared[counter + 2] += reciver[i * 16 + j * 4 + counter + 2];
prepared[counter + 3] += reciver[i * 16 + j * 4 + counter + 3];
}
counter += 4;
}
if( xSemaphoreGive( myBinarySem02Handle ) == pdTRUE )
{
xSemaphoreGive( myBinarySem01Handle );
}
} else {
xSemaphoreGive( myBinarySem01Handle );
}
}
if( xSemaphoreTake( myBinarySem02Handle, ( TickType_t ) 10 ) )
{
counter3++;
for( int i = 0; i < (length / 8); i += 2){
sender[0 + i] = prepared[i / 2] >> 8;

CubeMX stm32 FreeRTOS + USB host MSC for USB Flash memory

Using CubeMX, TrueStudio, an STM32F767ZI, and HAL, I am developing software to access a USB Flash drive using FatFS though the USB host port.
The board has a host and device USB connector attached to the MCU.
Within CubeMX, I configured FreeRTOS, USB Host MSC, and FatFS.
This works, I can see these different states when plugging and unplugging the flash drive:
--- Plugging in USB flash drive ---
HOST_USER_CONNECTION
HOST_USER_CONNECTION
HOST_DEV_ATTACHED
phost->device.speed: 1
HOST_ENUMERATION
HOST_SET_CONFIGURATION
HOST_SET_WAKEUP_FEATURE
HOST_CHECK_CLASS
USBH_MSC_InterfaceInit
HOST_CLASS_REQUEST
USBH_MSC_ClassRequest
HOST_CLASS
USBH_MSC_Process
processId: 3, Appli_state 1
USBH_MSC_GetLUNInfo
info.capacity.block_nbr : 623395
info.capacity.block_size: 512
capacity : 3116 MB
HOST_USER_CLASS_ACTIVE
FATFS_LinkDriver Failed
USBDISKPath:
processId: 2, Appli_state 2
USBH_MSC_GetLUNInfo
info.capacity.block_nbr : 62333951
info.capacity.block_size: 512
capacity : 31166 MB
--- Unplugging USB flash drive ---
HOST_USER_DISCONNECTION
HOST_DEV_DISCONNECTED
USBH_MSC_InterfaceDeInit
processId: 5, Appli_state 3
USBH_MSC_GetLUNInfo
info.capacity.block_nbr : 62333951
info.capacity.block_size: 512
capacity : 31166 MB
So, after MX_USB_HOST_Init(); was called in freertos.c all the above happened.
FATFS_LinkDriver() is called from MX_FATFS_Init().
But the functions in usbh_diskio.c are not called, so something went wrong there.
The pieces of code I'm looking at are these:
freertos.c, where MX_USB_HOST_Init() is called, after this the MSC is registered.
/* StartDefaultTask function */
void StartDefaultTask(void const * argument)
{
/* init code for FATFS */
MX_FATFS_Init();
/* init code for LWIP */
MX_LWIP_Init();
/* init code for USB_HOST */
MX_USB_HOST_Init();
/* init code for USB_DEVICE */
MX_USB_DEVICE_Init();
/* init code for LIBJPEG */
MX_LIBJPEG_Init();
/* USER CODE BEGIN StartDefaultTask */
MSC_LUNTypeDef info;
uint8_t lun = 0;
uint16_t val = 0;
/* Infinite loop */
for(;;)
{
/* USB Host Background task */
// USBH_Process(&hUsbHostFS);
val++;
if (val >= 1000)
{
if (processIdOld != processId)
{
printf("processId: %d, Appli_state %d\n", processId, Appli_state);
processIdOld = processId;
USBH_MSC_GetLUNInfo(&hUSB_Host, lun, &info);
uint32_t cap = info.capacity.block_nbr / 2000;
printf("info.capacity.block_nbr : %ld\n", info.capacity.block_nbr);
printf("info.capacity.block_size: %d\n", info.capacity.block_size);
printf("capacity : %d MB\n", cap);
}
// printf("1");
// fflush(stdout);
// HAL_GPIO_TogglePin(PIO10_LED_RS_ERR_GPIO_Port, PIO10_LED_RS_ERR_Pin);
val = 0;
}
osDelay(1);
}
/* USER CODE END StartDefaultTask */
}
usb_host.c, where USB is initialized, and I can see USBH_UserProcess is called when I plug/unplug the USB flash drive.
void MX_USB_HOST_Init(void)
{
/* USER CODE BEGIN USB_HOST_Init_PreTreatment */
/* USER CODE END USB_HOST_Init_PreTreatment */
/* Init host Library, add supported class and start the library. */
USBH_Init(&hUsbHostFS, USBH_UserProcess, HOST_FS);
USBH_RegisterClass(&hUsbHostFS, USBH_AUDIO_CLASS);
USBH_RegisterClass(&hUsbHostFS, USBH_CDC_CLASS);
USBH_RegisterClass(&hUsbHostFS, USBH_MSC_CLASS);
USBH_RegisterClass(&hUsbHostFS, USBH_HID_CLASS);
USBH_RegisterClass(&hUsbHostFS, USBH_MTP_CLASS);
USBH_Start(&hUsbHostFS);
/* USER CODE BEGIN USB_HOST_Init_PostTreatment */
/* USER CODE END USB_HOST_Init_PostTreatment */
}
/*
* user callback definition
*/
static void USBH_UserProcess (USBH_HandleTypeDef *phost, uint8_t id)
{
/* USER CODE BEGIN CALL_BACK_1 */
switch(id)
{
case HOST_USER_SELECT_CONFIGURATION:
printf("HOST_USER_SELECT_CONFIGURATION\n");
break;
case HOST_USER_DISCONNECTION:
printf("HOST_USER_DISCONNECTION\n");
Appli_state = APPLICATION_DISCONNECT;
break;
case HOST_USER_CLASS_ACTIVE:
printf("HOST_USER_CLASS_ACTIVE\n");
Appli_state = APPLICATION_READY;
break;
case HOST_USER_CONNECTION:
printf("HOST_USER_CONNECTION\n");
Appli_state = APPLICATION_START;
break;
default:
break;
}
/* USER CODE END CALL_BACK_1 */
}
The above part works fine, sofar.
Except the linking of the usbh driver.
Has anybody used this or know good working examples?
