Hello,
I have some trouble programming nRF Thingy:91 and therefore would like to ask some questions about possibilities to flash the devices:
1) It is not possible to program nRF9160 on Thingy:91 from nRF52840-DK, because it's from older generation (ARMv7, https://devzone.nordicsemi.com/f/nordic-q-a/51799/programming-thingy-91)
but is it possible to program nRF52840 on Thingy:91 from nRF52840-DK?
2) Considering aforementioned reasons, it should be possible to program nRF9160 on Thingy:91 from nRF5340-PDK. Is that true?
Unfortunately anything I try to do ends with nRF Connect (nrjfprog shows similar) showing such error message:
Could not fetch memory size of target devkit: Error: Error occured when get library info. Errorcode: CouldNotOpenDevice (0x4) Lowlevel error: JLINKARM_DLL_ERROR (ffffff9a)
I can program nRF9160 via USB using MCUboot, but that's not the same.
Any clue what I might be doing wrong?
