FiPy Core Dump

[robert-hh]

@adrien3d It used to be an option to erase flash and then reload the formware. I'm not using the standard firmware loader, so I do not know whether this method is avalable, and erasing the whole flash also erases the registration information for the communication modules. May @seb could shed some light on that.

Hey,

We are aware of this bug, it seems to be a race condition in the firmware. The next firmware release will have this bug fixed.

@robert-hh
Erasing the flash does not erase the registration details, these are kept in a database on our end and the firmware updater will automatically add them in with each update. If there is an issue with registration details we recommend customers email support@pycom.io and we will be able to reset the info in our database.

@seb Do you have any ETA for a firmware release that will fix this bug?

[seb]

@adrien3d
I can't provide an exact date but it will be included with the next firmware version which will be released within the next two weeks

@seb Can you provide some more details on this? We've been fighting a crash like this for the past week on the LoPy4.

Thanks,
Steve

Hi,
I've been informed it is caused by a race condition that occurs early in the boot process, I'm afraid that's all I know. It is actively being worked on as we speak and a fix will be released along with our next firmware update.

[adrien3d]

Does the 1.16.0b1 firmware solves the problem ?

[seb]

@adrien3d
Hi,

Unfortunately this issue is proving more elusive than we previously thought. It is being actively investigated, I will keep you updated with the progress.

[seb]

Can you please try the new firmware and report if this fixes the issue you are experiencing?

[adrien3d]

@seb Not fixing anything :/

[seb]

@adrien3d

If you can share the complete back trace generated by the latest firmware, I'll pass this on to the firmware team to look over again. With the back trace they can pinpoint where the error occurs.

I've merged what was comprehensible:

Looks like this line will provide you more infos:
