Re: Bug when connecting the USB cable

I tried to upgrade to DMCP_3.9. I still have the same issue when I plug the DM42 to USB power. I guess I'm still stuck to 3.5.

Re: Bug when connecting the USB cable

There is a new DMCP version 3.8 out there. I tried it full of hope, but I still got the same error when I plugged the USB cable, so the problem is not solved with this version :(

Re: Bug when connecting the USB cable

You can upgrade to the new firmware. If you encounter the problem, you can downgrade back to 3.5. It won't brick your unit. That's what I did. Chances are you won't have any problem because it seems to be quite a rare phenomen. And I guess the more feedback SM gets, the faster the issue will be fixed.

Re: Bug when connecting the USB cable

The problem seems to come from the DMCP part because I compiled the Hello world program. It works but the calculator still crashes when I plug the USB cable

Re: Bug when connecting the USB cable - Back to life !

I managed to downgrade to 3.5 firmware by removing the back case and pressing PRGM+RESET to get into bootloader mode, then flashing the old firmware with dfu-util. With the 3.5 firmware everything seems to be back to normal, I can access my FAT disk again so it seems not to be a hardware problem :) ...

Re: Python to RPN converter

Everything works fine now. I tried the "ampoule" program again and it works on free42 and on the dm42. I don't know what I did wrong yesterday :( The sommediv program works fine too, the pb is fixed. Thank you. By the way, maybe it would be useful to open a new subforum to post Python prog...
