Thanks Arne and others for the help. Really apprciate it. My meeprommer is finally working!

These are the steps I followed for debbuging:

1) Test wiring.
2) Test address bus with led array on the bus. Helped me found a wiring issu I hadn't ...

Thanks a lot Arne for your suggestions! Currrently I don't have another (e)eprom with a known data. But I'll follow your suggestions to troubleshoot this.
Cheers!

Hey, I was able to move a bit forward although still there is a way to go.
When using the sram (6264) I can write byte byte by using arduino monitor:


0x0000 : 61 62 63 64 65 66


Here a sequence 'abcdef' was written correctly to SRAM. If i try to write 8Kb using SimpleJBurn the result written ...

Thank you guys for the hints, really appreciate it.
I'm going to check wiring and then go over the arduino timing. Hope I can get it to work, but in the meantime i'm having fun

Cheers.

I did some testing with a 6264 i had lying around, it's very old and used, so i don't trust it very much.
When I write 8192 bytes to SRAM SimpleBurns doesn't get stuck:

When Writing data to SRAM (6264):

0x1FE0 44 45 53 49 47 4E 45 52 53 4F 46 54 57 41 52 45 42 49 4C 4C 20 42 4F 47 45 4E 52 45 49 ...

Hey Arne,

Thanks a lot for your response.
They are both good ideas to start troubleshooting, I don't have an SRAM, but I'll see if I can get one and check both thing you suggested. I'll let you know the results.

Thanks and cheers.

Hi everyone,

Sorry beforehand if I am posting onto the wrong thread, please let me know.
I just built up an eprommer following shematic https://github.com/mkeller0815/MEEPROMMER/blob/master/Hardware/Prototype_schema.jpg
This is the first parallel eeprom I built. I am trying to program a 8k .bin ...
