Ok thanks, it was no moaning anyway. I thought of everything I observed that might have to do with this issue in relation to your explanation above |

Still don't understand the issue re the test code. There are only three variables a1(), a2() and i. These show perfectly with list variables after the program exits (RP2350VGA firmware) |

Again works fine for me - the three variables listed as expected and no mismatches, same resolution. Could your flash be misreading somehow? |

The files stored on a: like mp3 play at least. I use this Pico since 7 months and didn't recognize problems yet..all I can say I could downgrade to compare. The copy speed is about 4Mb per minute from b: to a: which takes with the RP2040 with the same file 30 seconds.. I mean the 5Mb mp3 file Test is done with OPTION RESOLUTION 848x480 @ 336000KHz Edited 2025-07-18 05:10 by dddns |

I went through all my stored archives, too bad there is a gap and I found, that this is the last working version which runs the test program as well as FM170.bas PicoMiteHDMIUSBV6.00.02RC12.uf2 With RC20 it shows the same error as today's version: Missmatches: 9 > option list PicoMiteHDMI MMBasic USB RP2350B Edition V6.00.02RC20 OPTION SERIAL CONSOLE COM2,GP8,GP9 OPTION FLASH SIZE 16777216 OPTION COLOURCODE ON OPTION KEYBOARD US OPTION PICO OFF OPTION RESOLUTION 640x480 @ 252000KHz OPTION SDCARD GP1, GP2, GP3, GP0 With 6.00.01 it works and editor starts instantly. This 2 seconds hang when editor opens begins even before RC12 (edit: before/with b9) Hope again this helps! Edited 2025-07-18 07:36 by dddns |

The problem with the variables disappear was due to a corrupted filesystem on my a: drive. How and with which action it got corrupted I don't know. I wiped through this endless testing of cause many times my Pico and coming back to the latest version of 6.00.03 HDMIUSB I copied the same files again on the a: drive and now the correct free space is reported and variables a1(1000) and a2(1000) stay dim'ed and test program runs correct. The problem with the hangs seems to be due to the slow reading/writing speed to flash so the dumped heap takes so long to be written.

Help.... The BOOT button doesn't work anymore either. How can I load firmware now, e.g., clear_flash? Regards, Jan. |

You can then load any .uf2 file, including Clear_flash.uf2 |

phil99, Finally, it's working again, but now without PSRAM. I reset the controller from TeraTerm, after which the BOOT button responded again, but loading clear_flash didn't really work, and loading the original firmware didn't help either. Then I loaded a very old firmware version with an RP2350 (6.00.00B21?), and then it worked. Then I loaded the latest firmware, and it worked again. Tomorrow I'll add PSRAM. Regards, Jan. |

I think we have now established that my last fix works in all firmware variants for javavi's test program. I still need a test program to isolate what particular set of circumstances occur in FM that causes it to fail if I am to make further progress. |

| dddns Guru Joined: 20/09/2024 Location: GermanyPosts: 544 |
I cannot replicate at the moment but it occurred several times with enabled PSRAM, that some keystroke combination within running FM causes the program to error with "variable already declared". Ending up in console and try to rerun FM, it will error with the "already declared" again even though MEMORY shows no usage and issuing a CLEAR before. After a reset it runs again..

That gave me a clue to look at the FM Basic code EDIT FILE is called from within a subroutine. That is a complete no-no. From the manual SAVE CONTEXT command From the manual CHAIN command This warning should be added to the EDIT FILE command and the FM code will need to be changed before we look at any other issue Edited 2025-07-18 18:54 by matherp |

Many thanks :) I couldn't find an entry for RAM command in your latest manual draft |

| dddns Guru Joined: 20/09/2024 Location: GermanyPosts: 544 |
I would have a feature request: The COLOUR MAP command is very useful and makes sense with a LCD as well. Would it be possible to implement it in every version? Just a question and "nice to have" |

Geoff has updated the manual on his website to Revision 1. This should pick up a number of the issues raised in this thread and the 6.00.02 draft manual thread. |
