IMX6 NAND boot: image authentication fails

[abdulrasheed]

Hi,VladanJovanovic‌ igorpadykov
I'm trying to boot a customized SPL using NAND as boot source. I can see my code at execution address but the execution does not starts. I have taken the dump of buffer log created by ROM code.
My understanding is that ROM code reads first good block from NAND and place it in SRAM(internal ram). There it should execute the initialization given in DCD. and then copies the image with IVT table to the self address. and start executing from entry address.
In my IVT table I have provided all the addresses of DRAM(external ram). But i can see my code in both places at SRAM (0x00907400) and in DRAM at selfaddress. Also one more thing only 4096 bytes are copied to DRAM not the complete image. why is that?

after going through some threads I was able to understand this Boot ROM log.
What I don't understand is that why on reading page 0x00000282 (which translates to 0x141000 of NAND), authentication fails. even though i have taken nanddump and compared it with actual image and they both matched.

can you tell me what authentication status 000A1E33 means?

Hi Abdul

issue may be posted on uboot mail list, as nxp did not use or test spl on i.MX6,7 processors
