nrfutil not working on M1

[Constantin]

Hi,

I am using a M1 and I've installed the flashing scripts. But I am getting the following errors.

As I've already figured out it is a bug in https://github.com/NordicSemiconductor/pc-ble-driver/pull/271

And although it is merged into the master it is still not available via pip3. Any other solution to get the bug fix?

Kind regards,

C.W.

Ok, could you try to update your pip at first? I can successfully install pc-ble-driver-py==0.17.0 on my PC.

Dear Charlie,

yes this works under PC but not for apple M1. Therefore, I've asked when they are going  to release the version for M1 apple. So far I do not know a way to manually upgrade the sources of my pip?

If I type in

pip3 list --outdated

It is not listed.

Hence I am pretty sure, that it is not yet pushed as available package for arm64.

Kind regards,

Constantin

And as you can see here, it is still not available:
https://github.com/NordicSemiconductor/pc-ble-driver-py/issues/202

Furthermore, if you look under releases, there is no arm64 version.
