Hello!

I have a same problem with PIC18F26K22.
I use RS485 line, and I can not write flash.
Error is:
Initiating write...
     Searching for bl . . . . . .
     Found PIC18F26K22 fw ver. 3.0.2
     Waiting for the boot loader to be ready...ok
     Hex file successfully parsed
     Writing flash.... response timeout
     Writing flash...
     Write flash failed
     Tx 164 bytes / Rx 9 bytes / 3s
     Write failed
Or:
Initiating write...
     Searching for bl .
     Found PIC18F26K22 fw ver. 3.0.2
     Waiting for the boot loader to be ready...ok
     Hex file successfully parsed
     Writing flash....unknown response 0xFF
     Writing flash...
     Write flash failed
     Tx 159 bytes / Rx 9 bytes / 0,5s
     Write failed

But I can write the eeprom with same config:
Initiating write...
     Searching for bl . . . . . .
     Found PIC18F26K22 fw ver. 3.0.2
     Waiting for the boot loader to be ready...ok
     Hex file successfully parsed
     Writing eeprom...ok
     Tx 454 bytes / Rx 68 bytes / 3,8s
     Write successfully completed

It work without RS485 perfectly:
