Hi,

Happy new year!

My apologies for the late response.

Q1: Which distro are you using? If debian based; did you install the jlink .deb package?

Q2: Are you able to read/write any other .hex file (not modem upgrade)?

If you are really stuck here, you can do a workaround by trying to use pynrfjprog to upgrade the modem. Here's an example:

Kind regards,

Håkon

Hello,

Thank you for your reply.

Yes, nrfjprog is working. Here's the output of the command you pasted:

0x00000000: 20000C70                              |p.. |

Yes, udev rules have been loaded. I can even read output from the target through RTT.

Thanks.

Hi,

According to the error message, it has problems connecting and reading params from the nRF device.

If you use, for instance nrfjprog, from a terminal (this should read the content of address 0), does it work then?

nrfjprog --memrd 0 -f nrf91

nrfjprog can be downloaded from this link if you do not already have it:

*edit* Have you ensured that the udev rules for jlink is properly loaded? Its normally provided in /etc/udev/rules.d/99-jlink.rules and needs a udev reload or a reboot to take effect.

Kind regards,

Håkon
