Hi Peng, I'm still trying to get my i.MX8MM board running with mainline U-Boot. I'm using your patches and added some modifications, so I'm now able to run SPL and U-Boot proper.
One problem I have is, that accessing some regions in the memory map for peripheral register access, U-Boot crashes or hangs. Example: => md 0x302d0000 302d0000: 00000743 0000e031 00000000 00000000 C...1........... 302d0010: ffffffff ffffffff ffffffff 00000000 ................ 302d0020: 00000000 001012ec"Synchronous Abort" handler, esr 0x96000210 elr: 0000000040251b84 lr : 0000000040251ba0 (reloc) elr: 00000000bffa3b84 lr : 00000000bffa3ba0 x0 : 00000000bffb9000 x1 : 00000000308800b4 x2 : 00000000bff6e9b4 x3 : 00000000302d0028 x4 : 0000000000000000 x5 : 00000000bffb96a2 x6 : 0000000000000004 x7 : 00000000bbf3c330 x8 : 00000000bbf3c2f0 x9 : 000000000000000c x10: 00000000ffffffd8 x11: 0000000000000006 x12: 000000000001869f x13: 0000000000004238 x14: 00000000bbf3c59c x15: 0000000000000008 x16: 000000000000b900 x17: 000000000000ae80 x18: 00000000bbf41d70 x19: 0000000000000038 x20: 00000000302d0020 x21: 00000000302d0020 x22: 00000000bffb8e5f x23: 0000000000000008 x24: 0000000000000004 x25: 0000000000000004 x26: 0000000000000004 x27: 00000000bbf3c3b8 x28: 0000000000000002 x29: 00000000bbf3c330 Do you have any idea what might be wrong or how I could debug this issue?
