UART performance

[pulkin]

Make this work:

• all ampy commands
• uploading large chunks of data
• vscode plugin

@sebi5361, could you try the latest build with your vscode setup? I realized that the SDK spits out input in chunks as high as 1Kb so having a 256-byte buffer is definitely not enough. I fixed that in latest commits and it seems to work with all of ampy stuff.

I have just tried with my setup (VSCode + PyMakr) with a project that contains big files. Am still having some errors:

I have just tried again after having erased completely all the files from the board. And it worked perfectly with my setup. Files up to 40KB were copied flawlessly. Congratulations!

I fixed error codes: now it should display EIO 28 in your case indicating the lack of space.

[sebi5361]

I tried to observe this new EIO 28 error code but I didn't manage to make my board bump into such an error yet.

I saw the make "all ampy commands" to work and decided to post this here.

I've updated to the last version of the fw and I couldn't make rmdir ampy command to work, rm is working fine.

I was able to delete directories using rshell and the rm -r "DIR" command, and files using rm -f "FILE"

Tried mpfshell and the ls command don't work at all and crashes the connection, but I was able to delete files and directories using the rm command.

In all three options, connection was quite unrealible, many times I try to delete something and it just don't work at all, so I had to disconnect everything (power and communication port) and it started working again (lost quite some time cause I was just disconnecting the power or resetting module).

[pulkin]

I hope that automated testing will take care of most of these issues. I am starting looking into it.

[arlucio]

Ok, so I've installed the uhashlib fw build and now is the opposite, ampy and rshell doesn't work but mpfshell is working perfectly!

[pulkin]

That does not clarify the issue. If you want to help here you may intercept and investigate the UART traffic using interceptty /dev/ttyUSB0 bridge for example.
