Hi all,
Foundation model is closed source propertiary software, but i want to know how i can get more detailed and comprehensive technical support?
I want to know the work procedure of boot wrapper. For example, make CROSS_COMPILE=aarch64-linux-gnu- BOOTARGS='"root=/dev/vda2 consolelog=9 rw console=ttyAMA0"' FDT_SRC=vexpress-foundation-v8.dts IMAGE=linux-system-foundation.axf. What use are the arguments of BOOTARGS and FDT_SRC? Whether they are used by foundation model or real OS ? what real use is vexpress-foundation-v8.dts?
For linux to boot you need fdt (i.e. device tree) hence use of FDT_SRC is to prove device tree. BOOTARGS are used to pass booting arguments (like which console to use what is root device ? etc..). Boot wrapper adds/fills these BOOTARGS inside "chosen" node of fdt selected.
