nanopi-neo: mtda-service: Probe of the shared storage device failed

[WiseLord]

I have built recent (master) version of mtda for the nanopi-neo board and booted it.
I'm using default config documentation proposes:

root@mtda:/home/mtda# cat /etc/mtda/config
[console]
variant=usbf

[power]
variant=gpio
gpio=gpiochip0@203

[keyboard]
variant=hid
device=/dev/hidg0

[storage]
variant=usbf

Partly this works, when mtda device boots, the relay "clicks" and powers off DUT.

But when I check "mtda-service", it's in "dead" state. When trying to run it manually, the following output is observed:

root@mtda:/home/mtda# /usr/sbin/mtda-service -n
Probe of the shared storage device failed!
Failed to start the MTDA server!

USB flash drive is properly visible as /dev/sda.

Due to failed service, mtda-cli doesn't work:

root@mtda:/home/mtda# mtda-cli

When I comment out sections [console] and [storage] in /etc/mtda/config, mtda service is running and commands like mtda target on work.

So, it looks like "usbf" doesn't work, at least with recent builds.

I must have been a little rushed to open the issue...

Adding file=/dev/sda to [storage] section solved the problem.

Anyway, this moment is worth adding to nanopi-neo guide to have things working "out of the box".

Feel free to close the issue.
