I am trying to flash my custom board that uses the Raytac nRF52840 via SWD. I am trying to flash a custom bootloader onto the chip; however, JFlash is giving me an error. I'm running Windows 10 and I'm using a SEGGER EDU (https://www.adafruit.com/product/3571). If anyone could help me figure out what's going that would be great!
I've attached my log file from running nrfjprog via command line. Thank you!
