Programming Bus Pirate v4 without ChipKit
While on vacations I started a project where I needed to program a device (nRF52833) via SWD, as a programmer I wanted to use a Bus Pirate v4.0 I had on hand and OpenOCD.
After some hours of unsuccessful attempts I arrived to the conclusion that the firmware of my Bus Pirate has some bug on JTAG/SWD function. I downloaded newer firmware from https://github.com/BusPirate/Bus_Pirate/releases/tag/v7.0 and tried to burn it using pirate-loader but I was unable to communicate with the device even shorting PGC-PGD, tried lots of things until I remembered last time I programmed Bus Pirate was with my own compiled firmware and PICKit instead of using BP own bootloader, so probably I deleted accidentally the bootloader.
My only option was to program the Bus Pirate using directly the ICSP port, but my PICKit is at my home far away.Read more of this post
