Hello, I have tried to flash my Tinker Edge R by using the Flash tool (GUI) and the image from Tinker Edge R Debian 10 V2.0.5. In the GUI, I can select the image and my Tinker Edge R. I suppose my Tinker is in MASKROM mode. I have followed the steps from the Flash tool GUI manual, but everytime I get the notification that the flas has failed and that I should restart the Tinker into MASKROM mode and should try again. What goes wrong and how can I fix this? With kind regards.
