DSlogic Plus Pango Version (2023)

<< < (6/10) > >>

Yes, there was byte 35, I changed it to 30. Probably that's why utility could not read eeprom. It appeared as DsLogic Plus in DSView. But seems I messed with soldering of new RAM, because DSview was all time showing nonsense and all channels were changing it's values, even if not connected or connected to GND/VCC. Then I decided to solder back original RAM and to rewrite EEPROM. And I broke first pin of EEPROM after writing firmware into it. So I am now ordering some EEPROMS (AT24C128C-SSHM-B and CAT24C128WI-GT3) to replace it :)

I can make photos of board. Probably will do it tomorrow when sun will be shining enough for good picture

I was reading the source code of dsview. The new Pango version is labeled pgl12-2 inside the source code with PID equal to 0x35 for u2basic and 0x34 for plus version

So you must use 0x34 instead of 0x30 for your version

godor2008:
Ahh, so this the way from where these magic numbers come out. Thanks!
I will first try to restore it back to basic version with new EEPROM. Hope I will solder it well. And then after I receive new memory W9825G6KH-6 (256 mbit) will try to solder it instead of MT48LC16M16A2P-75D (256 mbit). Maybe I got that instability due to memory itself, and not the way I soldered it. From zooming my phone all contacts were well soldered and no short circuits.

And updating your utility to update firmware in EEPROM required only this new number 35? Or it's more complex thing you have to modify to make it work?

ahmad_k:
I will update it tomorrow.
For the memory, MT48LC16M16A2P-75D will not work, you need memory which has -6 in the end. What you have is slower than it should. that's why you have instability

godor2008:
Great thanks! So all reason was in memory itself. Well, gonna wait till it arrives from aliexpress to me to solder again :)
