Timeout Error with Raspberry Pi Pico - using version 0.0.29

[RyanGaudion]

I'm using the most recent version released 2 days ago (0.0.29) on Windows 10 however I get timeouts whenever I try to copy files to my Pico. Here are the commands I have used:

rshell cd Desktop/ cp main.py /pyboard/main.py

I have also tried these variations of the rshell command:

rshell -a rshell -p COM3 --buffer-size 512 Both of which also timeout (timeout waiting for first EOF reception)

Saving the files through Thonny works as intended so the file itself shouldn't be an issue.

I think I screwed up the 0.0.29 release. Can you try 0.0.30 instead?

Also, you shouldn't have to specify a buffer size. It should default to 128 (which is the default for the pico).

[RyanGaudion]

Hi @davehylands , thanks for the quick reply - just tried with v0.0.30 and it throws the same error:

So the fix that makes things work better for some people is this line here: https://github.com/dhylands/rshell/blob/e2820f679aa06d40c35dbd5c626a0402047e28f8/rshell/main.py#L1107

It shows as a comment, but the rshell code "uncomments" any lines that start with #rp2: when the board is a Pico. If you run with rshell -d then you should see that line as uncommented when copying a file.

You could try increasing/decreasing that timeout to see if it helps you.

If you clone the github repository:

git clone https://github.com/dhylands/rshell.git

You can run rshell from the local tree by using:

cd rshell
./r.py ...use whatever rshell options you want here...

@davehylands - thank you for your response and sorry for the long delay in getting back to you. Changing line 1107 to the below resolved the issue: #rp2: time.sleep_ms(50)

[RyanGaudion]

@davehylands - I've created a pull request (#154) for this - let me know if I have missed anything within the PR

[davehylands]

@RyanGaudion PR looks fine. I just need to find some time to make a new release.

In my case increasing the buffer size saved me https://github.com/dhylands/rshell/pull/168

In my case increasing the buffer size saved me #168

I got the same problem with the Pico. The delay did not help, but setting RPI_PICO_USB_BUFFER_SIZE to 256 did work

Same as you, PyboardError('timeout waiting for first EOF reception') on 0.0.31, while coping an 256KB file to Pico. Windows 10

Im getting this error on a LEGO large hub : timed out or error in transfer to remote: b'' Will you be able to guide me on how to trouble shoot? Thank you!

Try using rshell --buffer-size 256

Thank you for trying to help. This did not solve the issue I still get: /remote/remote.mpy' to '/pyboard/spike/remote.mpy' ... timed out or error in transfer to remote: b''
