Trying to get uboot SPL boot.bin to run on an SD card for the sama5d3 xplained board. All I get is RomBOOT and no other messages. I have tried throwing in a couple test pins to toggle in board_early_init_f but still not getting any debug. I can get at91bootstrap to produce a boot.bin that works on the sama5d3 xplained so I am assuming I don’t have a bad board. My boot partition is FAT16. To compile I just run the following on Debian Buster :
make mrproper make sama5d3_xplained_mmc_defconfig make
Cross Compiler is gcc-linaro-6.4.1-2018.05-x86_64_arm-linux-gnueabihf
When finished compiling I just copy the boot.bin to my BOOT partition.
Has to be something obvious that I am missing. Any insight is appreciated…
Hello,
Check the datasheet for sama5d3 SoC section 11.4.3. - Valid code detection (my datasheet is dated 2 Feb 2016 if it helps)
Basically the vector 6 needs to have hardcoded the binary size. Are you doing that ? Otherwise the RomBOOT code will consider your binary as faulty.
PS. make sure endianess is right, use a good hexeditor...
Hope this helps, Eugen
