Upgrading Bus Pirate firmware

Recently I brought my Bus Pirate from Spain to Prague, and I decided to update the firmware.

Prerequisites:

Compiling the pirate-loader

I found some pre-compiled binaries on the Bus_Pirate repository, but it was not working for me because of the arch used to create them.

Since we have the source code, we’ll compile them:

# Pirate Loader for BusPirate v3
gcc -O2 -Wall -force_cpusubtype_ALL pirate-loader_v3.c  -DOS=$(uname) -o pirate_loader_v3

# Pirate Loader for BusPirate v4
gcc -O2 -Wall -force_cpusubtype_ALL pirate-loader_v4.c  -DOS=$(uname) -o pirate_loader_v4

Upgrading Bus Pirate v3

First, we’ll need to enter in Bootloader mode:

$ screen /dev/tty.${USB_DEVICE} 115200 8N1

HiZ> $
Are you sure? y
BOOTLOADER

Then we’ll need to place the jumper between PGD and PGC:

Now we can flash the image:

$ ./pirate_loader_v3 --dev=/dev/tty.usbserial-A900fzzr --hex=BPv3-firmware-v6.3-r2151.hex
