Portable CM script failed (name = flash-tinyml-binary, return code = 256)

Hi, I am trying to reproduce the tiny results v1.0 by OctoML and flash the microcontroller board but the following issue is triggered. Can anyone please help?

hey @sahelib25, that looks like OpenOCD couldn't find your microcontroller board. is this running inside a docker container, and have you connected the microcontroller and updated your udev rules?

[sahelib25]

Hi @areusch, yes the microcontroller board was connected. But, I am not sure about the udev rules. Also, I did not use the docker container. Can you please help me with how I can update the udev rules?

[psyhtest]

@sahelib25 Is this running inside WSL?

[sahelib25]

@psyhtest, it is running on chai.

[areusch]

@sahelib25 try installing these udev rules, then unplugging/replugging the board: https://github.com/stlink-org/stlink/blob/develop/config/udev/rules.d/49-stlinkv2-1.rules

[psyhtest]

@psyhtest, it is running on chai.

chai is a Dell workstation (now running Ubuntu 22.04). (In the case of WSL, updating the udev rules might have been moot. I don't trust it when it comes to serial connections.)

@arjunsuresh & @areusch - I think we should add these notes and CM instructions as a tutorial for the TinyMLPerf folks at https://github.com/mlcommons/ck/tree/master/docs/tutorials . What do you think?

We can discuss it during the next conf-call of our taskforce on reproducibility or at the TinyMLPerf meeting...

[areusch]

@gfursin no objection and no discussion needed on my side as long as this solution fixes the problem. @sahelib25 can you let us know if that fixed your problem?

[gfursin]

Cool! Thank you @areusch!

[sahelib25]

Hi @areusch , it is still not working.

[sahelib25]

Hi @areusch, I have tried updating the udev rules once again. Now it is working fine. Thank you for your help.

Proxy tunneling failed: Gateway TimeoutUnable to establish SSL connection.

CM error: Portable CM script failed (name = get-dataset-imagenet-aux, return code = 256)

Note that it is often a portability problem of the third-party tool or native script that is wrapped and unified by this CM script.

So this like not the reason. How to fix the SSL question? waiting..

[arjunsuresh]

@nefuy Can you please try?

cm run script --tags=get,dataset,imagenet-aux --env.CM_VERIFY_SSL=no

[nefuy]

Thanks @arjunsuresh !

Seems not the SSL, because the "dropbox.com"

Retrying.

After I download the caffe_ilsvrc12.tar.gz and tar it, the next step is ? I would to know ..

[arjunsuresh]

@nefuy Can you please create a new issue explaining the issue as it does not seem connected to this particular issue?
