HummingBoard Mate. MicroSD Booting Error

NXP i.MX8M Plus
1

I am following the “HummingBoard Mate & i. MX8M Plus SOM Quick Start Guide” and I’m doing the booting from SD card option.
I am booting this img: sr-imx8-debian-bullseye-20230623-cli-imx8mp-sdhc.img
Once I have connected the power supply, the boot process starts. After about an hour, the board reaches this point:

I cannot reach the debian login.

Can anyone see anything in the logs? Thank you

This boot up should happen within seconds. What uSDHC card are you using?

I’m using a SanDisk Ultra 32GB microSDHC UHS-I and I used win32diskimager to flash the img. file.
The img. I flashed is sr-imx8-debian-bullseye-20230623-cli-imx8mp-sdhc.img

I also tried with a SanDisk Edge 16GB microSDHC UHS-I.
I also tried with an 8GB microSDHC SpeedClass 4(C4)
I also tried with a Transcend 2GB microSD

Which kind of uSDHC card should I use?
Thanks

I had this same behavior: sr-imx8-debian-bullseye-20230623-cli-imx8mp-sdhc.img does not boot on the HummingBoard Mate. On my board the U-Boot environment contains the variable fdtfile=freescale/imx8mp-hummingboard-mate.dtb but the Debian image does not contain this file.
