Quote from: eto on 00:40, 04 February 22I tried back and forth. PSU: no changedifferent firmware: no changeno finally cleaned the edge connector with a fibre pencil: no changeThe behaviour stays perfectly the same: first boot, Usifac is not recognized. Then I reset and it is recognized. Everything works perfectly until I reset again, then the computer hangs during startup.Am I the only one who experiences this?The problem is only on an early 464 model. On a 6128 it works perfectly fine.
Quote from: Devlin on 12:48, 04 February 22Reset and pause keys are wired directly into the edge connector - they're likely to always work.
Quote from: joruib on 15:36, 04 February 22Is there a way to order one? This looks really great!
Quote from: Fran123 on 19:23, 05 February 22UPDATING FIRMWAREI have to try install the firmware because my UsifacII has lost it (why? how? I don't know). And now I have some doubts:1- In what order should dupont cables be connected? I got the UsifacII in last June and it's different from the board in the guide (https://www.dropbox.com/s/pymv4sbxch3psin/Updating%20the%20Firmware%20of%20USIfAC%20II%20via%20ICSP%20v1.pdf?dl=0)2- Where should I set the voltage? I can change VDD Nom, VPP and VDD App, but the guide only says "set the voltage to 3.5V"3- Also it says tick "power target circuit from pickit3" but the MPLAP IPE I downloaded (v6.00) says "power target circuit from PM". Are they the same?4- What "programming mode entry" should I choose? The options are: "use high voltage programming entry mode" and "use low voltage programming entry mode"Thank you

Quote from: ikonsgr on 14:24, 06 February 22So, after late november, all boards sent (~25-30 so far) shouldn't have this problem.
Quote from: eto on 15:40, 06 February 22Can we apply this change on our older Usifacs too?
Quote from: Fran123 on 21:28, 07 February 22Little improvements:- print the firmware version at booting
Quote from: Fran123 on 21:28, 07 February 22- columns in CAT instead of a single list with pausesI think it is very easy, just print the file name and count the chars, later print 8-chars whitespaces, print a point and the same with extension, later print 8 whitespaces.
Quote from: ikonsgr on 22:05, 07 February 22The protections can only applied using pic kit4 programmer. If you want i can upload the "protected" version of hex file to try it.
Quote from: ikonsgr on 12:37, 08 February 22If anyone else has PICKIT3, you can try to flash this file, and let us know if it works ok.
Quote from: eto on 21:19, 08 February 22I could successfully write both my USIFACs. Thanks a lot!Now I'm just left with the 464 whcih won't boot with it. I just recognized something when I tried it: After I turn it on, I see the full boot message incl. the USIFAC message. Then it resets and during the automatic reboot it hangs before the USIFAC message appears. And as usual, everthing is fine (incl. reset) until I type |USB. Once I reset then, the system hangs just before the USIFAC message. (Also if I enable USB and then disable it again - both with |USB- reset will work properly. )I tried it with both USIFAC I own. So something must be special about this specific CPC model that is in conflict with the USIFAC boot sequence. I remember that the earlier firmwares did not reboot. Would it make sense to try the old one and see if it happens there too? Where can I find an old firmware, I didn't see it in the first post.
Quote from: Devlin on 22:39, 08 February 22Mine is a version 1 board, for example.
Quote from: OffseT on 11:45, 08 November 21Chany already asked me about such a support months ago, but according to the USIfAC documentation it didn't seem to be possible.Anyway, both UniDOS nodes and USIfAC documentations are available, so feel free!(and BTW, I cannot develop DOS node for all existing weird hardwares I do not even own)
Quote from: ikonsgr on 19:22, 10 February 22will be the usifac II placed on the 2-row socket?
