Hello,
Was you successful here? I would say the ramoops is not working in imx8mp. I tried to write something directly via u-boot like:
u-boot=> mw.l 0x00900000 0xdeadbeef 4
u-boot=> md 0x00900000 0x10
00900000: deadbeef deadbeef deadbeef deadbeef …
00900010: 00000000 00000000 00000000 00000000 …
00900020: 00000000 00000000 00000000 00000000 …
00900030: 00000000 00000000 00000000 00000000 …
u-boot=> reset resetting …
When read the data back after reset, they have been gone. I tried different addresses like 55100000 and so on. So I would say, u-boot is initializing the DDR memory with zero-s or something like that in SPL. So maybe the only possible solution is to use CONFIG_PSTORE_BLK.
Can someone confirm my statement?
Thank you,
Andy
