Hello,

I tried to use the ICSP port at the GQ-4X to programm a PIC 18F458.
I selected the 18F4580*ICSP to try this.
PGM to VDD and everything else like requested.
PGC and PGD to PGC and PGD.
GND to VSS and VDD/VPP to the needed ports.

I get the device ID 460 Rev. 65 but I can't read/erase or write the PIC18F458.

What I'm doing wrong?

Thanks in advance!
Regards, Martin
