No kernel, infinite rootwait..

Cécile , 08-18-2023, 07:22 AM

I have designed my own SBC based on i.MX6Q with 2GB of DDR3. I am trying to boot Debian on it (kernel 6.4.8, Debian 12), but unfortunately, my board is not booting up. I am stuck with an infinite rootwait. However, I managed to get it to work by changing my bootargs to have the initramfs console. But when I ran "exec /init", Debian did not boot up and no MMC devices were detected...

Does anyone have any ideas on how to finally boot up this board? I suspect it might be a DTS/DTB problem...?

Please find attached my DTS, DTSI, kernel .config, and boot logs (full logs and early printk enabled).​

Thank you for your help,

do you have the standard dmesg? I have seen boards hang if the thermal error was not fixed

hello, below the dmesg result, from the initramfs.

I found this link :

What is the difference between this and the official source from kernel.org? Non free binaries ?
Is this usefull for me?

Good news! My board is almost working now. I can reach the Debian login, but my board freezes after a few seconds.
And my ethernet phy isn't detected (mdio problem ?).

It's great it is working now. About PHY problem - it can be anything ... from HW problem to SW problem.
