Edge Impulse firmware update

[Matha 1]

Hello!

Since I haven't heard from Edge Impulse since posting an issue at their site with Edge Impulse firmware update for Spresense via Ubuntu terminal, please indulge the same post here:

Trying to flash firmware after downloading zip archive sony-spresense.

The output is:

$ ./flash_linux.sh

Checking Python dependencies OK

Using instructions for Spresense at web site.

Would appreciate some guidance on resolving this anomaly. In a separate project, I did successfully flash the Himax board using Edge Impulse instructions. I use that board for object detection demonstrations. I would like to repeat the exercise using Spresense. Unless there are specific steps or libraries that I have missed/skipped, I am not sure how to resolve the anomaly. All suggestions are welcome.

Thanks.

Kind regards.

Hey, @Matha-1

This might have something to do with the Python version you are using..
What is the version you are using?

[Matha 1]

@CamilaSouza That was the general consensus from several other persons too.

The original attempt was with v3.10 and subsequently I tried v3.6 - each failed with a different error message. Haven't had time to inspect the EI code (or perhaps it is beyond my expertise).

The suggestion to lower the rate was tried too without success.

Since there are other projects where I can apply the Spresense hardware (and Edge Impulse works fine for me with other boards), I'm going to deviate from my original plan and get the LTE extension board to do an alternate project.

Sorry for the late response. Thanks for your support as usual.

Kind regards.

@Matha-1
The issue was fixed on September 30th. See the latest release.

See Issue #3.
