Loading new firmware to my Bus Pirate 3.6A I got this message:

+++++++++++++++++++++++++++++++++++++++++++ Pirate-Loader for BP with Bootloader v4+ Loader version: 1.0.2 OS: WINDOWS +++++++++++++++++++++++++++++++++++++++++++

Parsing HEX file [C:\ONTWIKKELING\Arduino\Buspirate\Firmware_29-07-2019\busPirate.X.production.hex] Checksum does not match, line 6 Could not load HEX file, result=-1

In MPLAB: BUILD SUCCESSFUL (total time: 13s) Loading code from O:/Arduino/Buspirate/Bus_Pirate-master/Bus_Pirate-master/Firmware/busPirate.X/dist/BusPirate_v3/production/busPirate.X.production.hex... Loading completed

So no succes...

load the file, convert to uppercase then save. Use that and the checksum will be ok.

Did that, it works, sort of:

Error updating firmware :(

But the firmware does update:

Bus Pirate v3.5

This comment didn't make a lot of sense, so here's a bit more detail:

load the file, convert to uppercase then save. Use that and the checksum will be ok.

The busPirate.X.production.hex file generated by MPLAB has lowercase hex characters and the loader expects uppercase hex characters to pass the checksum. The easiest way to fix this is to open the generated hex file in Notepad++, select all, right-click and select UPPERCASE, and save over the old file.

This is a known issue (the firmware was successfully loaded) - it happens when the loader tries to program over the protected bootloader space, but since we're not changing the bootloader the loader just bails. See https://github.com/BusPirate/Bus_Pirate/issues/26#issuecomment-257071647

The issue can probably be closed.
