I'm failing at one of the first hurdles trying to flash the firmware to an ESP32 WROOM dev module, I'm getting the error: Error: open COM16: The system cannot find the file specified.
Any thoughts, apologies if this is covered elsewhere, I did search the forum first and didn't find any reference to this error.(edited)

endoMonkey 10/20/2023 09:46 AM

The device works fine in VSCode:

floitsch 10/20/2023 11:11 AM

@endoMonkey

it looks like we had a regression with Jaguar 1.13.
We are working on a fix.
You can try to downgrade to an earlier version for now.

endoMonkey 10/20/2023 11:14 AM

Yep, I'll give that a go right now. @floitsch I'm totally new to Jaguar, how do I go about rolling back to a previous version? Is there a post you can point me to with instructions perhaps?

floitsch 10/20/2023 11:14 AM

winget install --id=Toit.Jaguar -e -v 1.12.0

floitsch 10/20/2023 11:14 AM

Assuming you are using winget.

floitsch 10/20/2023 11:14 AM

I don't really have an easy way to test this, though. (No Windows machine right now).

floitsch 10/20/2023 11:15 AM

If it doesn't work, don't hesitate to come back.

floitsch 10/20/2023 11:15 AM

After downgrading, you will need jag setup again.

endoMonkey 10/20/2023 11:15 AM

I presume I need to uninstall the previous version first or will the new install overwrite the newer version without the need to uninstall?

floitsch 10/20/2023 11:16 AM

I think it should uninstall the old one first.

floitsch 10/20/2023 11:16 AM

But jag is really just one executable.

floitsch 10/20/2023 11:16 AM

So there isn't a lot of things that can go wrong.

floitsch 10/20/2023 11:16 AM

The majority of it is downloaded dynamically into the .cache directory, which will get updated with a call to jag setup.

endoMonkey 10/20/2023 11:17 AM

Looks like I'll need to manually uninstall the newer version first

floitsch 10/20/2023 11:18 AM

ok. so looks like you need to uninstall first...

floitsch 10/20/2023 11:19 AM

winget uninstall -e --id=Toit.Jaguar

(I think)

endoMonkey 10/20/2023 11:19 AM

winget remove --id=Toit.Jaguar worked to uninstall the newer version fine.

floitsch 10/20/2023 11:19 AM

Apparently remove and rm are aliases.

floitsch 10/20/2023 11:19 AM

So yes.

floitsch 10/20/2023 11:19 AM

And the -e is just for "exact match".

endoMonkey 10/20/2023 11:21 AM

Okay, that worked a treat and the flash command fetched and installed the firmware first time.

floitsch 10/20/2023 11:21 AM

Great!

floitsch 10/20/2023 11:22 AM

Sorry about that.
We hope to have this fixed within the next few hours.

floitsch

Sorry about that. We hope to have this fixed within the next few hours.

endoMonkey 10/20/2023 11:23 AM

Now all I need to do is learn Toit!

floitsch 10/20/2023 11:24 AM

Have fun. (And I mean it).
Don't hesitate to ask questions.

floitsch 10/20/2023 11:25 AM

I think the tutorials are the best place to start:
https://docs.toit.io/tutorials

erikcorry 10/20/2023 11:25 AM

I'm looking into the COM port thing.
Even with the newest Jaguar it works for me, so I'm wondering how to reproduce the issue.

erikcorry 10/20/2023 11:25 AM

Here's what my Device Manager looks like.

erikcorry 10/20/2023 11:25 AM

erikcorry 10/20/2023 11:28 AM

I'd be interested to see other people's device manager who see the issue.

endoMonkey 10/20/2023 11:31 AM

Here's mine:

theHuanter 10/20/2023 11:31 AM

mine is a CH340 as well

floitsch 10/20/2023 11:32 AM

Looks like it's the CH340 that stopped working.

theHuanter 10/20/2023 11:32 AM

the Olimex boards usually using them

erikcorry 10/20/2023 11:34 AM

OK good I have a device here with the CH340

erikcorry 10/20/2023 11:36 AM

Unfortunately that also works fine for me on my virtual WIndows box....

erikcorry 10/20/2023 11:36 AM

I'll try on the physical box.

theHuanter 10/20/2023 11:43 AM

what could the message "file not found" mean? what file?

floitsch 10/20/2023 11:54 AM

We might be hitting this: https://github.com/goburrow/serial/pull/13

"System cannot find the file specified" when the port Address numbe...

When the port Address number was greater, windows responded with the error "System cannot find the file specified".
The solution to this problem is adding some back slashes to the port Ad...

floitsch 10/20/2023 11:55 AM

According to the issue, adding backslashes to the port fixes it.

floitsch 10/20/2023 11:55 AM

Something like \\.\COM16

floitsch 10/20/2023 12:01 PM

https://support.microsoft.com/en-us/topic/howto-specify-serial-ports-larger-than-com9-db9078a5-b7b6-bf00-240f-f749ebfd913e
Maybe the upgrade of the serial module in Jaguar removed support for this? (We did upgrade it when going to Jaguar 1.13)

floitsch 10/20/2023 12:07 PM

We found it...
And it's our fault. Should be easy to fix.

endoMonkey 10/20/2023 12:14 PM

None of these work:

floitsch 10/20/2023 12:20 PM

Probably would need to be \\\\.\\COM16 but we are already fixing it.

floitsch 10/20/2023 12:21 PM

But it's not unlikely that the \\ approach won't work either.

theHuanter 10/20/2023 12:27 PM

I can remember that we did this once in the past because I had this issue

erikcorry 10/20/2023 12:47 PM

Thanks, everyone, for the help and the bug reports.

erikcorry 10/20/2023 12:47 PM

New Jaguar release coming up.

erikcorry 10/20/2023 02:50 PM

https://github.com/toitlang/jaguar/releases 1.16 available now.
Takes a bit of time before it hits winget, if that's what you use.

sorry to ruin the show, but doesnt seem to help

floitsch 10/22/2023 06:11 PM

There is Jaguar v1.16.1 out, but unfortunately I doubt it will fix the issue.

floitsch 10/22/2023 06:12 PM

However, you should be able to write jag flash --skip-port-check now.

Ignuskinas 10/22/2023 06:13 PM

neup

Ignuskinas 10/22/2023 06:13 PM

floitsch 10/22/2023 06:14 PM

I guess it doesn't help if you select the port with an argument --port COM17.

Ignuskinas 10/22/2023 06:14 PM

nope, same story

Ignuskinas 10/22/2023 06:14 PM

should i try 1.16.1?

floitsch 10/22/2023 06:15 PM

It shouldn't really make a difference, but it wouldn't hurt.

floitsch 10/22/2023 06:15 PM

However.

floitsch 10/22/2023 06:15 PM

If you could test older versions to see if they work, that would help us.

floitsch 10/22/2023 06:16 PM

And COM17 is the port the device is connected to?

Ignuskinas 10/22/2023 06:16 PM

well yes

Ignuskinas 10/22/2023 06:17 PM

1161 doesnt help

Ignuskinas 10/22/2023 06:17 PM

is that really because of port above 9?

floitsch 10/22/2023 06:17 PM

just to be sure: jag version shows the correct version?

Ignuskinas 10/22/2023 06:17 PM

Ignuskinas

is that really because of port above 9?

floitsch 10/22/2023 06:18 PM

It's likely, but I don't see any os.OpenFile in our sources anymore. At least none that should be executed.

floitsch 10/22/2023 06:19 PM

Give me a few seconds, and I will prepare a jag executable that prints a bit more debug information.

Ignuskinas 10/22/2023 06:19 PM

this worked fine

floitsch 10/22/2023 06:19 PM

So it is Jaguar itself that has issues.

floitsch 10/22/2023 06:21 PM

ok. It's a stupid != vs ==. I think.

floitsch 10/22/2023 06:21 PM

Give me a second and I will prepare an executable.

Ignuskinas 10/22/2023 06:22 PM

ok, happens:)(edited)

Ignuskinas 10/22/2023 06:23 PM

some jag --verbose would be nice

floitsch 10/22/2023 06:25 PM

Could you try with this?

Ignuskinas 10/22/2023 06:26 PM

one sec

Ignuskinas

some jag --verbose would be nice

floitsch 10/22/2023 06:27 PM

Agreed, but unfortunately not high priority.
Also, the Jaguar desktop version was written in Golang, and there is a bit of a preference to work in tools now that have been written in Toit. So typically Toit tools see a bit more love than the Golang ones.
Not really an excuse, but explanation

Ignuskinas 10/22/2023 06:29 PM

damn

floitsch 10/22/2023 06:30 PM

yeah. It's because it isn't signed.

floitsch 10/22/2023 06:30 PM

I just built it on my Linux machine using cross-compilation.

Ignuskinas 10/22/2023 06:30 PM

yeah

Ignuskinas 10/22/2023 06:30 PM

wait a moment

Ignuskinas 10/22/2023 06:33 PM

bravo, it works

Ignuskinas 10/22/2023 06:33 PM

floitsch 10/22/2023 06:33 PM

Great. Thanks for testing.
I will TBR (to be reviewed) the change and release a new Jaguar version.

Ignuskinas 10/22/2023 06:34 PM

brilliant

Ignuskinas 10/22/2023 06:35 PM

thanks for your help - this ESP was almost on its way to trashbin as I thought its damaged

floitsch 10/22/2023 06:36 PM

hehe.
It's really us who are grateful here. We are not using Windows ourselves, and without our user's help these kind of bugs would linger for a long time (and potentially scare new users).
So big thanks.
