Hi, recently I got PolarFire SoC FPGA based board I am working on FreeBSD support for. As a non volatile storage, it has eNVM used for HSS and eMMC as disk device. After reset, first thing run is HSS, which loads U-Boot from eMMC and usual boot process continues. It is possible, however, break the process and issue 'usbdmsc' command on HSS prompt. eMMC is then presented as USB disk. This works on Windows, and one or more (depends on partition table used on eMMC) disk drives are presented to system. It is possible to use balenaEtcher software to put some image there and do something with it. This does not work on FreeBSD. I see device being attached after starting 'usbdmsc' command, but no USB drive is being created. Could someone help me to diagnose this? Which command output (maybe 'usbconfig <something>') could offer some hint? Regards, Milan
