Hey Dev Zone! I'm attempting to flash FW onto the Thingy via the nrf52840 dev board (which includes JLink). I connected P19 header on nrf52840 to P9 on the Thingy. I downloaded the Thingy source code, followed instructions to build project/pca20020_s132 (github.com/.../Nordic-Thingy52-FW). The hex file I was left with was nrf52832_xxaa_s132.hex. I ran the following commands to flash the hex file onto Thingy: ./nrfjprog -f nrf52 --reset --log ./nrfjprog --eraseall -f nrf52 --log ./nrfjprog --program ../../nrf52832_xxaa_s132.hex -f nrf52 --log But I saw the errors: ERROR: JLinkARM DLL reported an error. Try again. If error condition ERROR: persists, run the same command again with argument --log, contact Nordic ERROR: Semiconductor and provide the generated log.log file to them.
Attaching log.log. Could you help? Could it be that I need to reflash the bootloader? Thanks very much in advance, Shubhangir
