iMX6 - kernel panic : gpmi-nand error ENODEV: DMA channel request failed

[abrahim]

Hi,

I'm using the defaut kernel 5.10.72 with imx_v6_v7_defconfig. I'm using a Nand device with ubifs.

The Nand seems to be correctly configured :

Hello,

It looks like you have not program the SD or NAND completely or the kernel has failed itself, since the error is due to a bad partitions, please check it, and burn the demo complete image to see whats happens there.

Regards

[abrahim]

Can you please share this demo image ? 
What can I check exactly ? 
I don’t use SD I only boot from Nand 

best regards,
