nRF9160 flashing error: Failed to read device memories.

[AD]

Hi, I'm trying to flash the nrf9160 through Visual Studio Code and I'm getting an error. I'll describe the error and what I tried to fix it below.

1 - First I tried to flash the chip:

nrfjprog --program /home/user/ncs/v2.1.0/nrf/applications/asset_tracker_v2/build_actinius_icarus_ns/zephyr/merged.hex --chiperase --verify -f NRF91 --snr 801036474 --log

Here I've got the error Failed to read device memories.

2 - To fix this error I tried to recover the chip, that also gives error:

nrfjprog --recover -f NRF91
Recovering device. This operation might take 30s.

Is there anything else I can do to try to recover the chip?

Thanks

Additional information

- I tried to flash this chip using Ubuntu 22.04 and Windows 10 with same results.

- nrfjprog version is 10.18.1 external

- I'm using the actinius icarus iot board.

Hi

What device are you using to program/communicate with the nRF91 board? We've seen something like this in the past, and that time it was due to the programmer used not being supported by our software tools. We do not support the Flasher series devices from SEGGER for example, as they are production programming oriented, but there's no reason why the Flasher series should not work specifically. My guess is that the device is not powered with the correct voltage. What voltage is the Icarus board power with, and what power does the programmer support?

We also have a whitepaper on nRF9160 Production programming available here that might be useful as well if you're in fact using a production programmer.

Best regards,

Simon

Hi,

I'm using the J-LINK EDU mini v1.0 programmer. The icarus board is powered through the USB plug, but I also tried to powered it with a 3.7 V  LIPO battery (measured 3.9 V with multimeter). The results are the same with either of the two sources.

I forgot to say earlier that I was able to flash this same firmware in another icarus IoT board using the same programmer and method.

Thanks

Then there must be an issue with the current Icarus board you're using. Are there perhaps any components missing on the misbehaving Icarus board? Can you check the voltages in on VDD on the nRF91 on this board if they look correct with your multimeter perhaps? Most likely there is a voltage mismatch somewhere, causing there JLink errors.

Best regards,

Simon
