$ jlink.compatible_firmware_version
Traceback (most recent call last):

$ pylink --version
pylink 0.13.0

Call works with JLink V6.88a.

Pylink CLI firmware upgrade and downgrade commands depend on compatible_firmware_version function.

The last version where compatible_firmware_version works is V7.52a.

Sorry about the late response here. Are there any logs if you run with verbosity enabled?

@hkpeprah any plans to look into this?

juhhov avatar Jul 20 '22 08:07 juhhov

It might be an issue in the shared library unfortunately, which we can't fix in this Python library, unfortunately :/

hkpeprah avatar Jul 20 '22 15:07 hkpeprah

I saw this issue as well with a J-Link Base Compact + software v7.58b (universal macOS). I upgraded to v7.84b and it still persisted. Only workaround was manually stub firmware_outdated and firmware_newer to return False. I believe it is something to do with pylink, since using JLinkExe works fine and a firmware update occurred the first time I used it.

I wonder if something has changed with the API we are using: JLINKARM_GetEmbeddedFWString. It seems to be returning -1 every time.
