Can not flash Nordic Thingy:91

Help
#1

Hi Edge Impulse community,

Could you please help me to flash my Nordic Thingy:91 development board. I was able successfully build Zephyr-based project by following instructions from here, but I can not flash it via usb cable using nRF Programmer tool. What hex file should I flash, since I can not flash merged.hex?

Thanks in advance!

Best regards,
Shakhizat

Hi @shakhizat,

Please see here for information about the compiled binary files: Using MCUboot in nRF Connect SDK — MCUboot 1.9.99 documentation. It looks like you need to use app_signed.hex. merged.hex is flashed if you are using the programmer (Like JLink).
