Problem writing to nrf52840

Question

I am using the following chip: NRF52840-QIAA-R 
 
 boggi@getshop-boggi:~/....$ nrfjprog --program /home/boggi/..../build_1/zephyr/zephyr.hex --sectoranduicrerase --verify -f NRF52 --snr 1050385234 --log [ #################### ] 5.321s | Erase file - Done erasing [error] [ Client] - Encountered error -102: Command program_file executed for 389 milliseconds with result -102 [error] [ nRF52] - The write access failed, but no cause could be determined.

 Is there anything I am missing here? 
 I attach the log for all executions above. 
 316576.log.log 
 
 I have also tried nrfjprog --recover --log, it executes correct, but does not help
