Hi ! I don't know if its because of the new firmware or anything else... but I also tried a new powersupply which must give enough power to the machine... so It happens very randomly if I edit a file and run a programm... sometimes the programm starts and then just freezes... I turn off and on the machine and then it works... but it is really anoying since I don't know what triggers this... I think it wasn't like that before I made the updates of the firmware or maybe I am figuring it out because I do more on the cmm2 now... any advice what i could do ? Thanks again for your help ! Cheers TweakerRay http://tweakerray.bandcamp.com |

It happens to me too. I recently updated from 5.05.03 to 5.05.05 but it does not seem to have fixed the problem. However, I have found that most, but not all of the freezes are caused by a mistake of mine. If your MMBasic program opens a file but fails to close it, the hang happens a lot. I suspect it means that the firmware is hung up waiting for an I/O completion that never happens. If I am careful to always include a 'close' statement in all the cases where the program terminates, the problem is largely avoided. Of course, if the program crashes on an error or gets the Ctrl-C two-finger salute, it can still happen. -Bill |

In the past several including me have found that the power source I was using was the issue. I was on a powered USB hub and that was the cause. On a good charger I have had very few issues and only a few crashes from my own tinkering. Try a diffent power souce. Edited 2020-10-11 15:45 by mclout999 They call me Shai-Hulud (The maker) |

I am using now a different powersupply which has much more power... So the CMM2 should get enough power... it was not the problem before with the old powersupply so I daubt it is a powersupply error... because I am experiencing the same with other powersupply... but it was worth a try ;-) I was just checking if other people may have the same issue...
