The set up which are used are a nRF52840 dongle programmed through nRF52832DK's debugger. After executing "erase all" in Programmer app, which erased the bootloader, it's not possible connect to the dongle. It should be right to assume that the nRF52840's flash was erased and not the DevKit's since the programmer identified correct hardware as 1Mb flash memory in Programmer app.
According to my understanding, I need to flash the bootloader again as stated in here: https://devzone.nordicsemi.com/f/nordic-q-a/37796/nrf52-dongle-can-t-program-with-segger-no-idcode-error-after-jlink-erase-all/147290#147290
Though I cannot make it work.
When trying to reinstall the bootloader in SES from path \nRF5_SDK_15.2.0\examples\dfu\open_bootloader\pca10059_usb\ses\Output\Release\Exe\bootloader.hex, following error message is received:
I have also tried to install the bootloader hex with nrfjprog by executing command "nrfjprog -f nrf52 --program \nRF5_SDK_15.2.0\examples\dfu\open_bootloader\pca10059_usb\ses\Output\Release\Exe\open_bootloader_usb_mbr_pca10059.hex --chiperase". This gives following error message:
How would you advice me to proceed?
