NRF programming issue

[Sufaira N]

Hi,

I am using the nRF5340 for my project.

In the production stage, I am facing an issue: after programming the nRF successfully, when I perform a readback, it shows that there is no code.

Why is this happening?

Hello,

Please describe your setup in more detail (what kind of programmer you are using, etc), explain the steps you use to load the FW, and finally how you are reading back the code again.

Thanks,

Vidar

Please include the exact nrfjprog commands you are using. Also let me know if you're able to read anything back with nrfjprog --readcode hex.hex or nrfjprog --memrd 0x0 --n 0x1000 after loading the FW, or if results in an error message.
