I use MPLAB SNAP. And i try pymcuprog ping But i can not connect. Mainly because the used device is not a HID device. So is there something i miss? Is it a bug? Has this been actual tested with MPLAB SNAP ?

xedbg commented 2 years ago

Repost: Yes, Snap is tested, and it is a HID device if its in AVR / EDBG / CMSIS-DAP mode. To get it into that mode, use Microchip Studio or MPLABX to make the switch by programming an AVR device.

Thanks for your reply. And this switch (i need to google how to do it but no problem) will it remain ? Or must i each time use mplabx to make this switch? I actually would like to avoid using mplabx at all.

xedbg commented 2 years ago

The switch is persistent, and will only switch back if for some reason you program a PIC in MPLABX.

thank you very much for your reply. ok, that is good news. i will try that :-)

mcsmark commented 2 years ago

ok, it was some work : install the mlab-x, then recover the firmware, do an avr project and then a virtual COM port was installed. so the error message is gone now. i get others but i can sort that out now there is communication :-). thanks again for the help.
