How to exit firmware upgrade mode? what to send over CDC/USB_Virtual_Serial ?

[Maksons]

Hello to all,

I bought USB2CANFD V1 adapter and at first tests get with 'X' in 'firmware upgrade mode' , had in mind it should return to normal operation after restart, but it didn't.
I'm using Linux (do not have Windows) , so no option to use WeActStudio_Upgrade_Tool .
So, question what should be sent over Virutal Serial USB/CDC to return to normal operation/existing FW in module ?

Hello,

My device automatically returns to normal mode about 15 seconds after entering upgrade mode.
And restarting the device also returns it back to normal mode.

Connecting a serial communication terminal may provide some clues.
If the device remains in upgrade mode, it should continuously send the character 'C'.
If not, the device is in normal mode but there must be some other issue.

Hello ! Same problem here. I did the Windows firmware upgrade but it didn't change anything. Could @WeActStudio respond to this ? Thanks.
