Tool/software:
Hello,
I am working on a custom board design using AM62X-SK-LP as reference. This board also has the same LPDD4 chip MT53E1G16D1ZW-046. I was using the same k3-am62-lp4-50-800-800.dtsi found in u-boot with SPL boot loader. But I want to use SBL to run the M4F application at boot up. I used board_lpddrReginit.h found in mcu plus sdk to build OSPI linux multistage bootloaders SBL1 and SBL2. Everything was going normally until the RAM copying didn't work as expected in some of the boards and console shows that the "some tests failed" message. But, interesting thing is that the SPL bootloader with same RAM configuration works on these boards.
It seems like the problem occurs only with SBL using MCU plus SDK. Should the focus be on software or hardware to debug this issue?
Could you shed some light on the next step in debugging?
Attached is the lpddr reginit configuration used in SBL.
Thanks,
Shibi Chakaravarthi Manoharan
