Try a STE DMA C398789-001A ...

I'm not lucky enough to have one of these to test.

Besides that -
@exxos
TEST in STFM C070789-001 REV F2 / 8Mhz no booster
DMA: CO25913-38 PH23-030 / OEM 1X
Corruption on writes over ASCI, tested both TOS 1.04/2.06

I'll try H5 next

Bonkers, 79789 boards are generally the least buggy revision... I wonder if theres been a faulty batch of US or some recent changes which broke it or something ?!

A DMA port would help... lol

Just to say thanks with all your help Steve, at least I can read and write in 32mhz which was more than what I could do previously

Your efforts is much appreciated

No worries. Really it's all because Exxos finds all these fixes which allows people like me to do work. So thanks Chris too

Steve's Phoenix A3 - Gipsy Kiss colour edition to the rescue!

Nope... Can't write to this ASCI2STM without corruption either. DMA is -38 / 9H1 61 which is QC tested from Exxos store.

I'll test the ASCI2STM in my TT now...

I have reason to believe this could be down to: SD card used and/or hard disk driver... I just need to find another SD card to test.

Bad card connections can cause issues like that as well..
