Fastboot is stuck

We are having problems flashing Linux on brand new 820uSoMs. We started the fastboot mode by pressing vol - and pwr button on the devkit, but comparing the debug output with working version, we are missing fastboot: processing commands:

When running any fastboot command we get:

< waiting for any device >

We also tried to use QDL by turning on the necessary switches on dev board and running

sudo ./qdl prog_emmc_firehose_8996_ddr.elf rawprogram-820.xml patch.xml

Qdl finished successfully (“partition 1 is now bootable”), but the problem remained.

Do you have any suggestions?

Is the device even detected at usb level? any usb trace in dmesg output? This is not a 96boards, are you flashing files provided by the vendor?

No the device isn’t detected at USB level, fastboot devices returns empty. We think the issue is with the development kit or uSoM.

Yes you should contact the vendor to get information about flashing steps and how the USB is routed.
