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:

> files
A:/
Error : Not enough Heap memory
> option list
PicoMiteVGA MMBasic RP2350B Edition V6.01.00b11
OPTION FLASH SIZE 16777216
OPTION COLOURCODE ON
OPTION KEYBOARD US
OPTION PICO OFF
OPTION RESOLUTION 800x600 @ 360000KHz
OPTION DISPLAY 50, 100
OPTION SDCARD GP24, GP25, GP26, GP27
OPTION VGA PINS GP32,GP34

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....

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

> files "b:1.bas"
B:/
19:54 10-09-2025 0 1.bas
0 directories, 1 file
> run"b:1.bas"
<no answer><crash>

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)?

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.
