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.
