I have a sparkfun nrf52832 breakout board that needs to have it's bootloader installed. I am using a Segger j-link to program the bootloader from sparkfun's gethub https://github.com/sparkfun/nRF52832_Breakout. I have tried both versions.
I am able to use the Segger j-link to flash the bootloader and the Segger J-Flash says that it is programmed (Using .hex file) but regardless of what I do the blue led doesn't flash as it should. I have erased the flash and tried several times. Each time it says it's programming was successful.
I am able to programmer using SES to flash leds etc no problem. The problem seems to be with the hex files supplied by Sparkfun. I don't think they are correct. I have noticed the the person who seems to have done the firmware is no longer with Sparkfun.
There are several people on this forum asking how to flash the nrf52832 with the bootloader and sparkfun hasn't helped anyone on this topic.
