Thank you very much for taking the time to investigate.
Problem is fixed as it appears that it was some test scripts still running in the background and thus blocking access to the daughter board.

Good day,

We have some issues with Axon M205. Sometimes for no reasons, one expansion card is not recognized and we lose all inputs/outputs. When that happens the only way I have found is to reinstall completely the OS.

It happened already on 3 different devices and it is a major problem for us as we send the devices in other countries and use them through an IPSec with mobile network and they don't have access to the internet easily (only SSH but all outside connections are firewalled en the network operator side)

You can see the evok page on the following images missing the Board n°1.

Do you guys have a workaround? Restarting Evok or the device does not help.

Thanks flash with USB did work. But i had to try with 3 differents one before it worked.

Good day,

I'm trying to flash Axon L505 with latest image (UniPi-Axon-OS-2018-11-09_v1.8.zip) trough service web interface but I get an error message file is too big (max 256mb) and file size is 260.
