Programmer in nRF Connect 3.11 does not have any "Write option"

BehicMV

Hi, 

When I open "Programmer v3.0.4" in nRF connect 3.11 and select my "zephyr.hex" file to flash to the nRF52940dongle, the "Write" button does not being activated. So, i cant flash my build in my dongle. What should I do except updating the "nRF Connect" beacuse of the latest version of "nRF Connect" does not work.

    Hi,

    What is the address range of the hex file you are attempting to write? When you are building a nRF Connect SDK project for the nRF52840 dongle, you need to build for nrf52840dongle_nrf52840, and in that case the start address will be at 0x1000. That is because the dongle has an MBR in the first page, and this cannot be overwritten. If the hex file you added has data in the first page (and that is not an MBR, which is just stripped out), it will not be valid and the "Write" button will be grayed out.
