I recently managed to extract the firmware from a nrf51822 chip over swd. The problem is, I am an absolute beginner to reverse engineering firmware, binwalk comes up blank, and other things I've tried, like firmware mod kit, have come up blank. I have also managed to open it in ghidra, but it doesn't seem to be quite right. I have found this git repository(https://github.com/DigitalSecurity/nrf5x-tools) that can help with reversing, and the scripts seem to be correctly identifying the firmware binary as from an nrf51822, but for actually reversing the firmware the script requires IDA pro's python api, which is not at all viable given its price. Is there any way to do something similar in ghidra or some other software?
