i.MX6ULL Nand Flash Booting

mjay — Wed, 19 Apr 2023 06:15:50 GMT

I'm trying to boot IMX6ULL NAND Flash.

For your information, I succeeded in booting IMX6ULL NAND Flash using buildroot 2018_11_4. ( uboot 4.15 and linux 4.15 )

However, the current condition is u-boot-2020.04.

Both uboot and linux use version 5.10.

There was no detailed explanation of the modifications caused by NAND booting in the NXP content, so I modified it with the contents of myir company.

Starting kernel ...

---------------------------------------------------------------------------------------------------

The problematic symptom for me is that the kernel does not come up after the 'Starting kernel' message.

I don't use Yocto and UUU.
Because I didn't understand the content.

So I downloaded and built Buildroot, Uboot, and linux, respectively.

Also, I am writing on the board using mfgtool.

So I need a guide on fixes to configure NAND boot for the latest version or 5.10.

Would it be possible to get some help?
