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:

[davehylands]

So the fix that makes things work better for some people is this line here:

rshell/rshell/main.py

Line 1107 in e2820f6

#rp2: time.sleep_ms(20)

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...

[RyanGaudion]

@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.

[ilan-schemoul]

In my case increasing the buffer size saved me #168

[willbelr]

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

Will you be able to guide me on how to trouble shoot? Thank you!

Try using rshell --buffer-size 256

Same here on rshell 0.0.36 and Pico W

Tried setting buffer to 256 (below) but also fails with default buffer of 32.
