Thanks to the hard work of Honken and JTR, the Bus Pirate v4 finally has a 100% open source USB bootloader.
If you have the v4 hardware, we could use your help testing the bootloader and new firmware. Test packages are available in the forum.
Thanks to JTR and Honken for their tireless work on this software.
There’s still a lot of work before Bus Pirate v4 is ready, but we just got one huge step closer

Wow! Great! I’ll test it out first thing tomorrow!
My BP v4 is almost assembled, just waiting for the CD4066 from china to arrive. :)
