SAMA5D3 Xplained Board NAND Flash Download

Wed Dec 02, 2020 11:35 pm

Hello.
I want to build from source code. (AT91Bootstrap, U-Boot and the Linux Kernel , rootfs)
And, I downloaded Yocto project/poky based demo from Demo archives. (linux4sam-poky-sama5d3_xplained-5.8.zip)
There seems to be no separate kernel binary download in the higher version demo.
I downloaded each source, built it, and replaced the files in the demo folder.
When I downloaded and booted onto the board, the following message was printed:

Hit any key to stop autoboot: 0

NAND read: device 0 offset 0x180000, size 0x87c2
34754 bytes read: OK

NAND read: device 0 offset 0x200000, size 0x375ea0

When I downloaded and booted onto the board, the following message was printed:
What you are trying to do and what you have done is not clear, and even seems contradictory.
Without a clear, concise, and complete description of what you have done, I have no guess.
You could enable kernel low-level debug, verbose decompression messages, and earlyprintk (or earlyconsole), but the cause is probably procedural.

Next time include a full boot log rather than just what you think is relevant.
The full log would include version numbers and some toolchain information that you choose to neglect to mention.
