The diodes are to show only the repair result, the flashing is a side effect and you should not be influenced by it. If you want to know something more, you need to connect to the uart and receive the repair log, but this is a 100% problem on the side of assembly errors.
I built the above-mentioned structure. 2h board, firmware 2.11

What is this fault? The green diode lights up, the system reset pin is 12V. on the + 5V line there is 5V. The voltage drops only for the time the START button is pressed.
I would like to comment on that. Whatever version 2.12 doesn't exist, what's in the link above is some rude modification to firmware 2.11. I have no idea what was changed there, from what I read from some rudimentary posts on another forum, something was corrected there, but I don't know what.
Why rude? Because the author, source and license were completely removed, and the website address was brazenly changed in the terminal log and the entry about commercial applications was removed. I don't mind patching someone else's code or layout. But folks, just a little respect for someone else's work and everyone will be happy.
Either I don't know how it works or something is wrong with my system.

It stands on - when I remove the UART, the same thing probably happens - only that - the green LED will light up, after a while it will go out and the red LED will flash. I am asking for help because I do not understand how it should work, so far it is one Atmega8 that has reached the "FF FF FF" signature.

Am I doing something wrong or is it complete and correct operation of this system ?? But why uP stop working with ISP? Performs the stabilized impulse power supply at the output is 11.8V. Can you please explain what and how ???
Hello electronics lovers, thanks to the author for a great project, thanks to a wonderful project like ATmega Fusebit Doctor, I unlocked three Atmega8 procks. I made the board some time ago, then modified it to the 2H version and programmed the ATmega 328 and it works.
I have an HP of 6 L and for the plates it is very good, I print on chalk paper and on the covers of colored letters. I have set the print to the maximum resolution. What you mean by saying that it cannot handle chalk paper and does not want to print unlikely.
He takes it on a roller and where it is to be - the fused toner begins to crumple it and separate it. If someone has one copy of the board in the new version - I would be grateful. Of course, further agreement at PW. Because here, rather, not a conversation about printers.
You can print it out at a service point. I have a laser engraving service. The guy said he could try. If you don't want to call a tile, you can also try it this way. I also saw ready-made fusbitdoctor plates on ebay.
