Using an FPGA to Glitch the Olimex LPC-P1343
After trying out hardware hacking using an FPGA to interface with target hardware, [Grazfather] was inspired to try using the iCEBreaker (one of the many hobbyist FPGAs to have recently flooded the market) to build a UART-controllable glitcher for the Olimex LPC-P1343. FPGA Modules (The cmd module intercepts what the host computer sends over UART, the resetter holds the reset line until the target is reset, the delay starts counting on reset and waits for a configured number of cycles before sending its signal, the trigger waits for the delay to finish before telling the pulse module to send a pulse, and the pulse works similar to the delay module and outputs to the power multiplexer.) When the target board boots up, the bootROM reads the flash and determines whether the UART goes to a shell and if the shell can be used to read out the flash. This is meant for developing firmware and debugging it in the bootloader, only flashing a version when the firmware is production-ready
