I'm writing a UBoot driver for bitbanged NAND and need to add it to the device tree.
Because this device is not on any bus and only references GPIO pins, I want to put it directly at the device tree root (like it's done for gpio-leds):
/ {
nand {
status = "ok";
compatible = "onfi,bitbang-nand";
pinctrl-0 = <&nand_pins>;
pinctrl-names = "default";
nand-bus-width = <8>;
data-gpios = <&gpio 40 0>,
<&gpio 41 0>,
<&gpio 42 0>,
<&gpio 43 0>,
<&gpio 44 0>,
<&gpio 45 0>,
<&gpio 46 0>,
<&gpio 47 0>;
ale-gpios = <&gpio 38 0>;
cle-gpios = <&gpio 39 0>;
nre-gpios = <&gpio 36 0>;
nwe-gpios = <&gpio 35 0>;
nce-gpios = <&gpio 44 0>;
nwp-gpios = <&gpio 44 0>;
rdy-gpios = <&gpio 47 0>;
};
};
When the device is declared as such, UBoot does not recognize the device, and it's not even present in device tree node binding log. When I add a subnode to the device, UBoot recognizes nand as a device:
/ {
nand {
compatible = "onfi,bitbang-nand";
#address-cells = <1>;
#size-cells = <1>;
pinctrl-0 = <&nand_pins>;
pinctrl-names = "default";
nand#0 {
status = "ok";
nand-bus-width = <8>;
data-gpios = <&gpio 40 0>,
<&gpio 41 0>,
<&gpio 42 0>,
<&gpio 43 0>,
<&gpio 44 0>,
<&gpio 45 0>,
<&gpio 46 0>,
<&gpio 47 0>;
ale-gpios = <&gpio 38 0>;
cle-gpios = <&gpio 39 0>;
nre-gpios = <&gpio 36 0>;
nwe-gpios = <&gpio 35 0>;
nce-gpios = <&gpio 44 0>;
nwp-gpios = <&gpio 44 0>;
rdy-gpios = <&gpio 47 0>;
};
};
};
Why the first example is not considered a device and the second one is? I couldn't find anything relevant in the specification.
This was a silly mistake. According to the specification, the right status value is okay, not ok. So, the node nand was read by dm_scan_fdt_node in drivers/core/root.c and discarded as disabled. Second version was found because absent status field is equivalent to the enabled device.

Hello There i am using swift 5.0 and developing BLE App.
As we have android app there are using default function as below
byte nByte[] = Name.getBytes( charsetName: "EUC-KR")
Output of android
Value[0] = 32 Value[1] = 30 Value[2] = 32 Value[3] =
32 Value[4] = 31 Value[5] = 31 Value[6] = 32 Value[7] = 37 Value[8] = 2d Value[9] = c3 Value[10] =

We used in iOS different type of string convert as below
Code 1
let rawEncoding = CFStringConvertEncodingToNSStringEncoding(CFStringEncoding(CFStringEncodings.EUC_KR.rawValue))
let encoding = String.Encoding(rawValue: rawEncoding)
let strEUCData = "20221127-충북80자9015-X-02-1212121.TXT".data(using: encoding) ?? Data()

All above functions given wrong byte array.
Any help will be appreciated.
Thank you.
They are the same data. The Android output is in Hex (base 16) number and the iOS output is in decimal (base 10) number:

I am using static library "libWebRTC.a" to create IOS App by binding it using Xamarin binding.
when I call _factory.VideoSourceWithCapturer(capturer, mediaConstraints); in this code the application crashes
RTCVideoTrack CreateLocalVideoTrack()
{
RTCVideoTrack localVideoTrack = null;
AVCaptureDevice.RequestAccessForMediaType(AVMediaType.Video, (bool isAccessGranted) =>
{
if (isAccessGranted)
{
String cameraID = "";
for (int i = 0; i < AVCaptureDevice.DevicesWithMediaType(AVMediaType.Video).Length; i++)
{
if (AVCaptureDevice.DevicesWithMediaType(AVMediaType.Video)[i].Position == AVCaptureDevicePosition.Front)
{
cameraID = AVCaptureDevice.DevicesWithMediaType(AVMediaType.Video)[i].LocalizedName;
break;
}
}
//do something
RTCVideoCapturer capturer = RTCVideoCapturer.CapturerWithDeviceName(cameraID);
RTCMediaConstraints mediaConstraints = DefaultMediaStreamConstraints();
RTCVideoSource videoSource = _factory.VideoSourceWithCapturer(capturer, mediaConstraints);
localVideoTrack = _factory.VideoTrackWithID(#"ARDAMSv0", videoSource);
}
else
{
}
});
return localVideoTrack;
}
and this is the message :

I am attempting to display an array which I receive from a JSON Dictionary onto a UITableView but I keep getting an error. I am trying to display all the comments for a given Instagram Picture onto a Table. Here is how I am attempting to display the cells:
MessageTableViewCell *cell = (MessageTableViewCell *)[self.tableView dequeueReusableCellWithIdentifier:MessengerCellIdentifier];
NSDictionary *instaPics = self.instagramData;
NSArray *commentArray = instaPics[#"comments"][#"data"];
NSString *commentText = [commentArray valueForKey:#"text"]; // Error occurs here
Message *message = self.messages[indexPath.row];
cell.titleLabel.text = message.username;
cell.bodyLabel.text = commentText;
Here is the error I receive:

You are trying to get a value from key in a NSArray on:
[commentArray valueForKey:#"text"];
NSArray is not a dictionary has not keys (has multiple comments), should be accessed by his index.
[[commentArray objectAtIndex:0] valueForKey:#"text"];
Probably you will want, iterate over the comments and on each comment get his "text"
You can replace this line :
NSString *commentText = [commentArray valueForKey:#"text"];
with
for (NSDictionary *comment in commentArray ) {
NSString *commentText = [comment valueForKey:#"text"];
cell.bodyLabel.text = commentText;
}
Gonzalo is right. Your accessing commentArray like a NSDictionary but it is actually a NSArray. That causes the crash.
NSArray *commentArray = instaPics[#"comments"][#"data"];
It looks like a wrong access of key value..
As per my understanding you are trying to get value of comments.
your Json data contains root & child key value like,
comments
count
Data
caption
images
likes
...
Here your Comments having child value like count,data.
So can write the code to fetch value of comment > data>text
--------1--------
NSMutableDictionary *response = [[[json valueForKey:#"comments"] objectAtIndex:0]mutableCopy];
NSMutableDictionary *data = [[[response valueForKey:#"data"] objectAtIndex:0]mutableCopy];
NSString *text = [data valueForKey:#"text"];
----OR----2--------
NSMutableDictionary *response = [[[json valueForKey:#"comments"] objectAtIndex:0]mutableCopy];
NSArray *textarr=[response valueForKey:#"text"];
I have an intermittent crash bug when posting images to an S3 bucket using the iOS SDK.
These crash bugs are formed of 2 errors, but originate in the same area of the SDK.

Both errors are focussed around line 41 of S3Request.m which reads
[self.urlRequest setValue:self.host forHTTPHeaderField:kHttpHdrHost];
These errors are intemittent and so far I have been unable to replicate the issue exactly, so don't know what the value of self.host when the app crashes.
When the upload succeeds, the value for host is the correct bucket name.
To try and replicate this I have tried to run the requests with the host name set to nil, set to an incorrect bucket name, on wifi, 3G and with no connectivity but none of these conditions causes either condition to occur.
Does anyone know what is causing these issues and therefore what I may have to do to fix them?
===UPDATE===
I finally managed to replicate it, i have no idea how. I just got the SIGSEV.
This is the status of the request object at the the S3Request object at the time of the error

After I have updated monotouch to Version 5.2.13 my App crashes when I touched inside a UIButton.
About my Code: (it's a question of a LoginView):
I have a UIViewController which includes a ScrollView.
For each User the ScrollView provides a UIView (the UserImageView).
This UserImageView contains a UserImage, Username and so on. Over the UserImage lays a UIButton which should catches the Touch-Events to selected a User.
This Button causes the Exception below more precisely the HitTest method from the UIView.
I get the following Stacktrace:

I'm not sure your use of AddTarget is a good way to hook up a UIButton's click.
You should be using clickHelper.TouchUpInside to wire up click events. This is a standard C# event.
Another option would be to wire up an action to this event inside your XIB file in XCode.
