PyOCD and J-Link GDB Server issues #4

Hi, I am trying to use the NXP k66 freedom board with GDBfuzz It has a Jlink dongle on board. I tried to launch GDBfuzz using PyOCD but GDBfuzz cannot bootstrap, because it identifies crashes on every single input. I also tried using J-link GDB server, in this case GDBfuzz crashes and disconnects. Have you tested GDBfuzz with another GDB server besides st-util and openOCD?

thanks

Hi, we had GDBFuzz successfully running on a Cypress development board using PyOCD and on the ESP32 using a Segger J-Link with OpenOCD. Have you tried setting the log level on DEBUG and checked if there are any helpful messages popping up?
