Hello,

the latest RP2350 HDMI and VGA firmware gives me an error when executing files command. This happens only for Resolution 800 and 848 for A: and B: drive, all others work:


Another observation for HDMI: My programm executes and I have 32k free heap in Resolution 1024 Mode 1. With same conditions, in Resolution 1280 Mode 1 it errors with heap and in Mode 3 only 5K remain. Not sure but looks too much?

Oh no, here we go again.

RP announced RP2350 A4 stepping where they fixed the GPIO bug (E9).
To support this version we need to update the SDK.
Good they fixed the bug.
Not good to change SDK again....

Already changed in the latest betas

Hi Peter,
I don't know if this is important or intended behavior: If I run a zero-byte Basic file with RUN, the Pico crashes without an error message and can only be revived with a hard reset.
PicoMice 2350, version 6.01.00b5

Kind regards
Michael

Can't replicate in b11. Please specify exactly how you are doing it

I tried different 0-byte files with the extension "*.bas". First, I tried starting with FM, then from the prompt (after reset) with RUN "filename.bas".

But this only happens on the SD card. It seems to work fine on "a:".

I hope this helps
Michael

Edit:
I solved it in the FM by querying the file size beforehand. So it's not an urgent problem!

Edit2:
I hardly dare to ask: is there a function to query the active "mode" setting? Like: mm.info(Mode)?

Will look at this next week when home

All good, there's no rush.

@Peter,

Thanks for fixing the 2040 XMODEM bug. File transfers using MMCC work flawless now (tested on non-VGA version).

@Peter,

I have problems with b12
- On 2350 gamemite: when running petscii robots, framebuffer merge does not work anymore. This works fine on b11.
- On 2040 gamemite: when copying from B:/ to A:/ files get corrupt.

Sorry, this is not a good move forward.

Bugger, there is a day one problem with zero byte files on the SDcard I'm trying to solve. I thought I had a solution but it looks like it has had a side-effect

OK on RP2040?

Hi Peter,

I think you have already a clue on the file copy issue, so I maybe too late, but here is some background screenshots.
The original file is on B, open in build in editor



After copying to A, in editor... Looks like the first 512 or so characters are missing.




EDIT: Framebuffer merge problem: also present on 2040.

Works for me on RP2350 running Petscii. Haven't got a Game*Mite to test on - may be something to do with the OPTIONS. Please try OPTION RESET GAME*MITE if you haven't done this recently

My options which should be fairly similar



Attached my RP2350 firmware which should have fixed the copy issue
