I updated to PicoMiteHDMI MMBasic USB RP2350A Edition V6.03.00RC23
But I am having problems transferring files using FM and selecting and copying with F5.
I also performed a flash nuck, which didn't help.
I don't even have video anymore, so I performed an option reset on the Olimex USB.
Now I have picture again and FM seems to be working, but restoring the backup from b: to a: causes the entire system to be reset.
FM is no longer working.

So I'm just going back to V6.03.00RC21
Now FM is working fine again
What I also noticed is that option disk load "V5.03.00RC21.opt" isn't working properly anymore?
So, with some copies of the option list still in Notepad++ and transferring line by line via Tera Term, I have it back in order. Now I just have to wait and see if I'm the only one with these problems?

Option disk load can't always work between versions, sometimes it can but you should assume NOT and set the options by hand with any new version

Peter,

I had previously saved "V6.03.00RC21.opt" using option disk save, and after the problems, I reloaded V6.03.00RC21 using option disk load "V6.03.00RC21.opt", after which the pico started up but there was no video, so I blind option reset olimex usb (enter) y (enter)
Reset and the picture returned. After that, I manually copied the list line by line from notepad++ and pasted it into Tera Term.

Peter,

The MIN build rc23 is okay for Game*Mite.

Aha, I guessed so, since I could add Nobukun's shooter game (16k) to the image, and still have space for the high-score folder, and files with scores.

Thanks, the Game*Mite has more value now , simply because there are more games in it. More fun to play.

When the official release is same, I can release the 2040 uf2 image. Tom will be happy...

And I will also add a zip that can be installed on the sd card, that contains the games that are too large to fit

Petscii, Gems and Rocks, Maxitrek, etc...

Volhout

P.s. with these changes the Game*Mite Petscii runs faster (13fps) than the VGA version (10fps). Not a problem, 10fps is perfectly playable. But the GM verion used to run slower to equal speed. And now it is faster. Maybe related to accidental cache misses.

Something's not working right with the new version on PicoCalc.

I flashed my PicoCalc with "PicoMiteRP2350V6.03.00RC23.uf2" and loaded my mm.startup from SD card:

Sub MM.PROMPT
Print Cwd$ "> ";
End Sub

Sub MM.STARTUP

Print "Welcome to the machine!"
Print "======================="
Print
RTC gettime
Print "Time: ";Time$
Print "Date: ";Date$
Print
Print "Temp.:";Format$(Pin(Temp),"%+.2f");"` C"
Print
If MM.Info(CHARGING)=1 Then Print "Akku wird geladen!"
Print

batt$=""

For i=0 To 100 Step 5
If MM.Info(battery) >= i Then
'Print Chr$(219);
batt$=batt$+Chr$(219)
Else
'Print Chr$(177);
batt$=batt$+Chr$(177)
EndIf
'Print i
Next i
Print
Print Tab(12) "+---------------------+"
Print "Akku:";MM.Info(battery);"%";
Print Tab(12) "|";batt$;:Print "|"
Print Tab(12) "+---------------------+"

For i=1 To 3
Option BACKLIGHT KBD 255
Pause 100
Option BACKLIGHT KBD 0
Pause 50
Next i

Print
Print
/* Print "Filemanager laden (J/N):";
Input a$
If a$="j"Or a$="J" Then
Run "b:\minifm.bas"
Else
Drive "B:"
End If
*/
Drive "B:"
End Sub

When I save this file using LIBRARY SAVE, my PicoCalc no longer displays anything after a reboot, and I can no longer access it. Re-flashing doesn't help—even "flash_nuke.uf2" doesn't work. The PicoCalc remains blank. A very old version brought the device back to life. Unfortunately, re-flashing with the current version causes the device to remain blank again...
The only thing that has changed in the current mm.startup file are the commented-out lines at the end.

Don't understand what you are saying. Which part of the library code causes the problems? If it is running minifm then the code is probably running out of some resource.

Okay, first I ran "flash_nuke.uf2". Then I flashed "PicoMiteRP2350V6.03.00RC23.uf2". So far, everything was fine, and I got a message saying that Drive A had been formatted.

After that, I loaded the file above from the SD card and saved it using LIBRARY SAVE.
From that point on, nothing works anymore - the LCD stays black. Re-flashing with "flash_nuke.uf2" and flashing with "PicoMiteRP2350V6.03.00RC23.uf2" doesn't help. The LCD stays black.

It looks to me like something is going wrong with LIBRARY SAVE, and a "flash_nuke.uf2" file doesn't fix the problem.

Right now, my PicoCalc is bricked. I've never had a problem like this with it before.

Yes, but what part of the file causes the problem? Can you save something simple to the library? What happens if you load the file without saving to the library and then reboot? Does MM.STARTUP then run OK? Does this file work on an older version? Can you identify a version when the problem occurred? I don't have a PicoCalc so can't test.

I can't get the PicoCalc to work at all right now. I flashed an ancient version, and that got it working again. Flashing it again with "flash_nuke.uf2" and "PicoMiteRP2350V6.03.00RC23.uf2" immediately resulted in a black screen again. No indication that Drive A had been reformatted - just nothing at all...

Except for the section that's been commented out, I've always used the file above, and it's worked without any problems.

Do you have any idea how I could completely reset the RP2350? It doesn't seem to be working with "flash_nuke.uf2"...

Are you using a Pico module with an A4 stepping chip? If so you need to find an updated version of flash_nuke. The old version doesn't support A4 stepping

I don't know what stepping the chip has - I can't open the PicoCalc right now. I've now found a newer version of flash_nuke, and after using it, I was able to run RC22. Even after saving the file above, everything works as usual.
It seems to be a problem with RC23.

Please try this version and report. If the problem still occurs change this line

Quote Print "Temp.:";Format$(Pin(Temp),"%+.2f");"` C"

to use str$ instead of format$

When I flash RC24 (after flash_nuke), the screen stays black. RC22 works again after flashing it one more time.

Quote When I flash RC24 (after flash_nuke), the screen stays black.

With or without the library code?
If without try OPTION RESET PICOCALC from the serial console to properly set up the pico
