 Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me. |

I googled rpi config.txt read only and no one has made it writable it seems, very odd. same with getting admin to change the file attributes. thing is I had this running at 2200MHz by adding over_voltage=8 arm_freq=2200 force_turbo=1 so I must have edited config.txt at some time.?? |

In Trixie OS find arm_boost=1 and comment out then add 3 lines # Run as fast as firmware / board allows #arm_boost=1 over_voltage=8 arm_freq=2200 force_turbo=1 |

@dddns- I do not know if you use mmedit to write code and load to pico but if you get a rpi 400 and install mmedit you will need this line in terminal sudo usermod -aG dialout $(rpi user name) This will make it connect usb to pico. I just installed Trixie on another ssd and set it as before and it is working fine at 2200 overclock. youtube playback good. |

You can do anything (including overwriting the whole system!) using sudo If you want to do several things as root you can typically use sudo bash and you have a root shell. You can get out of it using exit (or end of file, usually Ctrl-D) But remember it is easy to ruin your system!! (which is why they've made root a bit harder to use) John Edited 2026-03-05 08:24 by JohnS |

Dear Jim, I've got a RPi 4 on 64bit trixie and installed your mmedit5_rpi. MMedit seems to work, but I've problems with MMCC, it doesn't accept <Return> and <Ctrl>-<C> and hangs quiet often. Perhaps I missed something. Greetings from the upside of our beautiful planet, Martin |

Martin, I have been doing some work on the <CR> key problem in the various versions of Linux. It does depend on which Enter key is pressed. I wasn't aware of any ^C problem. If you are using full menus, there is a ^C button. Does that work? I will have a look. I use a VNC for my RPis and that could make it difficult to see keyboard problems. I have other things happening preventing me from doing much work on MMEdit at the moment. Jim VK7JH MMedit |

Hi Jim, There’s no difference between <Return> and <Enter> (i.e. between the alphanumeric and numeric keypads), and it doesn’t matter whether I access the RPi locally or via TigerVNC (which I usually use). So I use <ESC>, <^C> and <Send+CR> via the menu; that works. (Yes, ESC is one of the ‘naughty’ keys too) The great thing is: Data transfer from MMedit via MMCC to the Pico is working well – that’s the most important thing. (Unfortunately, it’s not currently working between MMedit on Windows and my CMM2, but that’s probably a different matter) Best regards, Martin |
