Thats pretty impressive - load a different firmware, rip off the flash memory, re-route the modulation pins of the lasers, and boom, it works! If the "show" files are in .ild format, you can find heaps more on the internet. ILD stands for ILDA, its the standard protocol for talking to laser, although your's does lack the 25pin ILDA connection. Nice work!

Well done on the workaround. At a guess, the SD card is only supposed to have programs / on it and not the manual which ended up in the flash. I assume that you didn't have access to the firmware source, as then you could have changed the GPIO allocation. As you know, use caution with those mains connectors, although the cables were sleeved the connector rivets were exposed.

@BuyitFixit

Жыл бұрын

Thanks Ralph. Unfortunately no source code and also the chip was read protected and had some copy protection in the firmware too! Based on the unique chip data. That was why there was another file to upload to the chip to bypass it. Good point on the connector. I didn't notice that. The chip shouldn't be copying anything into flash. It should just read the file into ram or read the sd on the fly. I'm wondering if the copy protection was somehow triggered and it bricked itself or it tried to update itself (if it has an update mechanism). Guess we'll never know but it was definitely an odd one! 👍👍👍

What was the flash memory chip for, in the end it wasn't needed?

@BuyitFixit

9 ай бұрын

I think it was so store some built in images and presets in case you didn't have an SD card. It wasn't used on the firmware I flashed it with.

So what do you think the root cause was? Just a corrupted flash on the processor? Was there no way to change the code to the new flash to change the pinouts instead of doing a hardware mod?

@BuyitFixit

3 ай бұрын

Yes, corrupted flash.You could have changed the code, but that would have required a lot more time and effort as you would need to find a decompiler first, and then try and figure out where all of the I/O pins were assigned and used, modify them, then test / debug etc.

@@BuyitFixit Gotcha. I didn't look at the github to see if the source code was included or not.

*** - After 3 minutes in.. I would guess it was either the microcontroller firmware.. or the flash file he loaded.. one got corrupted... there has to be some type of factory reset procedure? Also that extra socket on the microcontroller board... 4 pins (RX, TX, GND, 3.3V).. could be UART for flashing... [EDIT]: After watching half way.. i was correct.. also the 'Adobe' in the .bin file you read, was from the .pdf file that was on the SD card.. that is how he corrupted it.. ur prolly only supposed to have the 1 file ur writing on the SD card..

I think the controller thought the pdf file was a firmware update and overwrote the firmware with the pdf. I did see something after making this on an Aliexpress listing saying do not insert the SD card without formatting it first or something so I guess they became aware of the issue.

COULD HAVE JUST CHANGED CALLS IN PROGRAM

Would have probably been the i/o port numbers not calls, but the I'd have to install a disassembler and figure out what registers did what for that particular chip.

If you had access to the source code you may have changed the port pins over to the existing laser connections you have, rather than removing the flash? Either way - very nice fault finding! 🙂

@BuyitFixit

Thanks. Yes changing the i/o pins in the software would have been easier, another way would have been to put the code in a disassembler and edit it manually, I've done things like that in the past too. Most recently was where I needed a service password for a solar inverter I repaired and the company said it was out of warranty and buy a new one. I show all of the emails in the video I did about it.
