Subject: [U-Boot] am335x board i2c_probe fails from nand boot

Message-ID: <CADnUhn3RTk7FCk2YsRcJT5_7Krh1Qo3QBfSJ6CX28sKVNk6-1A@mail.gmail.com> (raw)

"The Expected Linux image was not found. Please check your NAND
configuration" message is coming from:
common/spl/spl_nand.c
In practice this message seems coming from the fact that header of kernel
image can't be identified from offset after executing:
nand_spl_load_image(CONFIG_SYS_NAND_SPL_KERNEL_OFFS,,)
So, something gets broken in while executing nand_spl_load_image. Perhaps
CONFIG_SYS_NAND_SPL_KERNEL_OFFS value.
"Card did not respond to voltage select!" is coming from:
drivers/mmc/mmc.c
