Updating the firmware on a PC with linux EC25EU, EC25EUX


The firmware of some devices is updated correctly.
But some devices cannot be updated the first time. I think the device is in QDL mode. How can such devices be updated

The preliminary analysis may be because the firmware version you are currently using is relatively low. It is recommended that you use the latest firmware. I will send it to you by mail, please check

Thank you, Felix!
I will report on the results a little later.
