/diy/ - Do It Yourself

Hey /ohm/, anyone have much experience with bus pirates? I seem to be having some trouble updating/changing the firmware on mine, and I'm worried I may have bricked it. Everything worked as intended before I started

I have the pic related, which is a BPv3 (03b, I think). I wanted to switch to being able to use JTAG, which requires a firmware swap. Here's a timeline of what I did:
>Load BPv3 XSVF Firmware onto board via pirate loader
>Loads fine with no errors
>Lose ability to communicate via serial (offline mode)
I know it can still hear me though, as the RX/TX LEDs (can't remember which) will flicker faintly when I type
>Find out all this firmware depends on new bootloader (v4, I have v2something)
>Think "Well, better update bootloader then push new firmware in"
>Do that, all via pirate loader, cuz Linux
>Still no luck
"bootloader mode" returns BP4+ via serial after any input, though, making me suspect at least the bootloader is updated. Firmware be damned
