Yocto and Buildroot provide many open source package and library for quickly compile. You don’t need to compile those package alone. Buildroot 1. Enter Buildroot menuconfig $ make menuconfig 2. If you don’t know where the package is, type “ / ” to search 3. Compile, re-pack the Image, and program it...

RAM Size in Linux is Different from Hardware, because VC8000 decoder and display driver reserve some memory You can check it from U-Boot and Linux device tree For example, you can see the Linux kernel device tree below Display driver reserve 48 MB and VC8K reserve 24 MB, so Linux cannot see all the ...

There are two methods can be determined Run application before login 1. Create a file in the /etc/init.d and the name determine executing order For example, you can name it as S42Hello, and it will execute after S41dhcpcd 2. The content can be refer to other files in init.d folder Run application af...

I2C1 use pin PN4 and PN5 to communicate failed, but used them as GPIO successfully.

You need to check if the circuit have pull high resistance or not.

For example, you can read/write WDT register at Linux stage but not CLK_SYSCLK1(0x40460208) and SSPCC. SSPCC belong to TZS register, so it only can be modified at TF-A stage. Linux kernel doesn’t allow users modify CLK_SYSCLK1, so you need to modify clock source code and compile it again. #MA35D1 #S...
