Part Number:AM4376
Tool/software: TI-RTOS
Hello,
I am trying to run the RTOS template application on a custom board. In order to do that I'd like to boot the board via a SD card. Hence, I am following the procedure described here : 
The "booting via SD card" part refers to the image : <mmcsd_bootloader>_ti.bin which I guess in my case should be bootloader_boot_mmcsd_a9host_debug_ti.bin (renamed MLO)
If I understood well, it is this secondary bootloader that should load the application to the DDR memory. Therefore, the SBL should know what are the Pinmux, clocking and DDR configurations on our custom board, right ?
How can I update these configurations in the bootloader image ?
I am using :
Code composer studio 8.2.0
sdk RTOS 5.02.00.10
AM4376 Custom board
Thank you in advance,
Best regards,
Gilles
