Sorry. The developer is now on holiday until the 28th. One thing you could investigate is if the issue still happens if you disconnect the ps2 keyboard and operate from a remote usb console.
Can anyone replicate with the same firmware and/or the HDMIUSB firmware?

Hi Peter,

no problem take all the time you need

I tested your latest firmware:

Quote PicoMiteRP2350V6.01.00EXP.zip
Edited 2025-12-23 05:40 by matherp

with the HDMI USB version (my PCB allows bridging VSYS and USB to use an USB Hub)

The problem is the same, you can see for yourself, I shot another video in which you also can see the version and OPTION LIST - this time I used the default resolution of
640. As said, there are absolutly no problems with the RC25 version. I nuked the flash every time to be sure.

But on "PicoMiteRP2350V6.01.00EXP" there is definitly something wrong:

Video with HDMI usb version

EDIT I:
I also tested the official release (https://geoffg.net/picomite.html) again:
HDMI Version (USB and PS/2) got problems when RESOLUTION is 720, when set
to default RESOLUTION 640, no problems with "PLAY MP3" - I hope this helps.
But yes, also the official release has this bug.

EDIT II:
It is even more complicated: At first it works with default resolution on the official release, but ONCE set to RESOLUTION 720 "PLAY mp3" crashes the system.
Setting RESOLUTION back to 640 doesn't help anymore. A OPTION RESET doesn't help either. Only re-flashing the firmware helps and not setting resolution higher than 640. Once set to 720 all the problems with playback mp3 will occur.

So version RC25 is the most stable with no problems at all.

Have a wonderful holiday!!

Greetings
Daniel

hi toml_12953,

robert.rozee said hi Peter,
all very PASCAL like

have just scanned through the thread, it looks like you haven't yet implemented anything like the pascal WITH statement:
[...]
(the use of DO in the context of mmbasic is probably superfluous)

the use of WITH saves on a great deal of duplicated typing and hence consumed flash program space.

It looks like Peter was going for Microsoft BASIC compatibility. If so, then in that case, you'd type
[...]

just because microsoft erred in not implementing something like WITH ... DO to simplify the syntax, that is no reason for us to repeat the same omission. i'm sure there are many places where mmbasic deviates from microsoft basic - and for very good reason!

cheers,
rob :-)

Amnesie said Hello Peter,

There is a bug with play mp3 again (in latest version and offical release). When executed it does a reboot + strange behavior.

EDIT: There is ALSO a problem in the latest offical release, please see the attached video, since the problem with play mp3 isn't constant!

Greetings

I can't make play mp3 fail no matter what I do. I use an LCD as console and have a Pimoroni Pico 2 as my CPU with PSRAM active. I'm using PicoMite 6.01.00 (not EXP)

The problem occurs in HDMI versions (PS/2 and USB).
