Hello,
Got an Atari STe 1040 that is unable to correctly partition a SD card in a UltraSatan. I partition it but when it reboots it doesnt see it. It also has trashed content of folders for example, i started devpac and made some preferences changes and saved it, now the devpac folder is empty.
So i guess this is a DMA issue. I have exxos PSU and a 68HC000 processor that troed was so kind to donate but the problem still exists.
If i have understood it correctly my next step is to add a pullup om the DMA buss? I have checked the mandatory fixes page but are still a bit unsure. So i wanted to confirmt that it is this that i should do
/zChris
Atari STe 1040 trashing UltraSatan SD card

Yes this is the next logical step to take.

Re: Atari STe 1040 trashing UltraSatan SD card
Indeed. However, the UltraSATAN (at least the Lotharek one) pulls the ACSI bus *hard* to 3.3V and some DMA chips just can't handle this.
Intro retro computers since before they were retro...
ZX81->Spectrum->Memotech MTX->Sinclair QL->520STM->BBC Micro->TT030->PCs & Sun Workstations.
Added code to the MiNT kernel (still there the last time I checked) + put together MiNTOS.
Collection now with added Macs, Amigas, Suns and Acorns.

Re: Atari STe 1040 trashing UltraSatan SD card
Do you mean strong pull-ups? It is surprising as there doesn't seem to be any pull-ups at all in Jookie's original US schematics, just voltage dividers. But, I don't know, it is possible that Lotharek made some changes. Or do you mean something else?stephen_usher wrote: ↑Thu May 19, 2022 1:06 pm Indeed.

Out of curiosity, what driver are you using?
Collector of many retro things!
800XL and 65XE both with Ultimate1MB,VBXL/XE & PokeyMax, SIDE3, SDrive Max, 2x 1010 cassette, 2x 1050 one with Happy mod, 3x 2600 Jr, 7800 and Lynx II
Approx 20 STs, including a 520 STM, 520 STFMs, 3x Mega ST, MSTE & 2x 32 Mhz boosted STEs
Plus the rest, totalling around 50 machines including a QL, 3x BBC Model B, Electron, Spectrums, ZX81 etc...

Re: Atari STe 1040 trashing UltraSatan SD card
I don't know why but the data lines are pulled strongly to 3.3V if the UltraSATAN I have isn't driving them.ijor wrote: ↑Thu May 19, 2022 4:50 pmDo you mean strong pull-ups?

Putting a 2.2K resistor to +5V doesn't shift the voltage at all, not even a centivolt, so whatever is pulling the lines to that value is very strong. Goodness knows how much current the DMA has to sink to pull them down for data transfer.

@stephen_usher Maybe they are just zener clamped to 3.3v ? Even so that wouldn't be good for the STE which has driver chips

Tried this program and only got * which was good i think. Run it for like 20 minutes.exxos wrote: ↑Thu May 19, 2022 2:03 pm Try this program https://www.exxosforum.co.uk/forum/viewt ... ?f=25&t=43
UltraSatan and card is OK since i can partition it with my H4 board and it reads it correctly on Atari STe. Its when its writing that its a big chance of corruption AND it doesnt work to partition the SD card with ATari STe. Using HDDRIVER 11
