New BP, v3b, firmware update fail :(

November 29, 2019, 12:50:50 am

hope someone can save me.. here are the steps I did:

Cloned https://github.com/BusPirate/Bus_Pirate

Went to the bottom for this link:

Firmware Flashing

Refer to building-and-flashing-firmware to see how to build and flash this firmware.
(url: https://github.com/BusPirate/Bus_Pirate/blob/master/Documentation/building-and-flashing-firmware.md)

Installed XC16

Installed MPLAB-X

Followed the "Building" section.. MPLAB-X showed success:

BUILD SUCCESSFUL (total time: 15s)
Loading code from /root/bp-latest/Bus_Pirate/Firmware/busPirate.X/dist/BusPirate_v3/production/busPirate.X.production.hex...
Loading completed

Followed the flashing steps... with (failed):

Error updating firmware

Now, I can't access BP, although it appears I can trigger the bootloader with PGC and PGD (mode LED lights up)?

I'm not sure what to do next

I noticed sending hello to the bootloader responds (with PGC and PGD jumpered):

Update:

Ok.. from what others have responded when others had the same behavior after an update, I need to use a pickit.

Navigating through the bus pirate info out there is 90 percent of the challenge... its unfortunate

It would be nice to know where I went wrong though given I tried to follow the steps.

Dec 1, 2019 - Update... ok... restored/unbricked the bus pirate with MPLAB and a pickit3. Easier than I had figured.

./pirate-loader_lnx --dev=/dev/ttyUSB0 --hello

I think the issue may be that the --hello only says hello to the bootloader and then quits. There is probably another command --program or something that flashes the firmware, that's my guess.
