Hi,
it is working for the first time. If I do reprogram the chip then I have the following message:


017-05-09 12:13:19 +0200 - Programming...
Target has invalid calibration data (0x00).

Device Erased...

Programming...

The following memory area(s) will be programmed:
program memory: start address = 0x0, end address = 0x45
configuration memory
program memory
Address: 0 Expected Value: 2828 Received Value: 0
Failed to program device
2017-05-09 12:13:23 +0200 - Programming failed
Pass Count: 49

It is the first time I face with a so small PIC devices... Is it critical ?
thanks
Ambro
