Firmware upgrade procedure

[KhazAkar]

Hello! Since we got gsusb firmware version for cfdc/cfuc devices, is there any firmware upgrade procedure available for user to do? It would be great to have it, for existing customers ;)

Cheers, Damian

Hi, just go to DFU, you can do this from Java application and then upload new firmware.

Hi To switch device to DFU just send over Serialport

https://github.com/ucandevices/CFDC_embedded/blob/830aa4006f803b5ef1e0f853225115626095f5bf/firmware/Inc/ucan_fd_protocol_stm32g431.h#L32

which should be 0x04

I'm trying, but my minicom on ttyACM0 still says 'Offline', as well as sending commands using echo or cat does not help. I'm setting 115200 baudrate using stty -F. Do I miss something?

[KhazAkar]

Exact commands I'm using: stty -F /dev/ttyACM0 115200 echo -e "\x04" > /dev/ttyACM0 minicom -b 115200 -D /dev/ttyACM0 (shows offline) No reaction on any of this.

Tested on different machine, where I didn't had 'offline' - sending commands using gtkterm, minicom and screen don't work. Using pyserial module as well. No reaction from HW. Any idea? FW is at version before port to gsusb.

[Lukasz-Juranek]

this is no longer supported write me an email on @.*** with your address. I will resend you new devices, it would be great if you could send me back this broken one. I will look into why it is not working as expected.
