I came across with a problem these days!
The problem is that after I writing debian os from microSD card to emmc, beaglebone clould i9 says:
Failed to write to 'state.settings'. ENOSPC: no space left on device, write
and nothing works at all!
So I decide to format the emmc on beaglebone!
Can anyone help me how to get this done?
Maybe you are using the wrong debian version. Currently (12.03.2020) the version "Debian 9.9 2019-08-03 4GB SD IoT" is just usable for microSD card and is not recommended for eMMC flashing. If you want to flash the eMMC you can currently use the version "Debian 9.5 2018-10-07 4GB eMMC IoT Flasher". Unfortunatley, does this version not include the graphical desktop.
I want to try blinking a led on PRU core of beaglebone black rev c.The program I want to write is in c language and o.s. is ubuntu without emulator as described in TI's hands on labs for pru.
I tried blinking led program with TI am335x cortex-A8.
I want to try same with PRU.
I am confused with the dependencies required by PRU.
Any suggestions or guideline will be very helpful.
you can use this example to blink the a led. It is working on my side.

I'm trying build a linux system on beaglebone black and following to mastering embedded linux programming book, however when I boot my u-boot on beaglebone black, I have received a error: unknown command 'nand' - try 'help'.
Does anybody have any idea of what did I do wrong or did I miss something?
If you are in Chapter 3: All About Bootloaders → U-Boot → Using U-Boot:
This is NOT an example meant to be executed on a BeagleBoneBlack.
It is a generic example of a U-Boot command that possibly could work on hardware that actually has NAND flash. The BBB does not have raw NAND flash, it has an eMMC and a micro-SD card slot.
If that's not where you are in the book, please provide chapter information and what you are trying to achieve.
BTW: please also note that there are errata for this book, especially around U-Boot and the NAND commands. You might want to verify if they apply to your reprint.
The command nand is only available in U-Boot if CONFIG_CMD_NAND=y is configured.
Use make menuconfig for configuration.
I'm in an unusual spot. The built in screen on the laptop I'm using right now is broken so bad I can barely see anything besides random flickering lights on it. Because of that, I got and plugged in a monitor to my laptop. This moniter works fine once Windows 7 has already loaded.
The issue is: I'm trying to open the BIOS/boot menu to live boot off of my USB, but I can't see anything. How do I make it so that I get visual output on my monitor early enough to open the BIOS/boot menu?
If it's a Dell laptop, try FN&F1 or F1
