Tool/software:
I am currently trying to implement secure boot for the AM263PX processor. I have been reading through sbl_null in {sdk install path}\examples\drivers\boot\sbl_null\am263px-cc\r5fss0-0_nortos and sbl_ospi_multicore_elf in {sdk install path}\examples\drivers\boot\sbl_ospi_multicore_elf\am263px-cc\r5fss0-0_norto to try and understand what the code should look like when doing ospi boot with mcelf image files.
There are a lot of resources explaining what the higher level implementation should look like for the sbl during secure boot however I can't seem to find good documentation in the developer guide AM263x MCU+ SDK: Developer Guides explaining each function call seen in sbl_null for example or sbl_ospi_multicore_elf. This would be very helpful for when we write our own sbl as it might look very different to sbl_ospi_multicore_elf.
Any help in finding this detailed low level documentation would be very appreciated, thank you.
