Raspberry PI PICO ATARI ST Hard Drive Emulator (WIP)

[DaveC]

Oh wow. That's what I'm seeing with my independently-built one on my STE.

I've never had DMA issues before, but haven't done the DMA pull-ups and I think I've an original CPU in there. I assumed it was my shoddy handiwork, but thse look to be the same symptoms so perhaps I need to get the STFM working to test there too.

Least my problems may help you with yours, hadn't done pull ups anywhere with mine either as it had always previously just worked!

My drive arrived today, plugged it in and it worked perfectly until I started messing about with the IDC utils on the card. I seemed to have wiped the boot partition while trying to add another. Didn't RTFM :D

Anyway, since this is my first Atari HD, I thought it would be useful to go through the installation process myself. So I downloaded IDC pro from Jookie's site but when I try and format the disk I get the error 'Sense error $FE'. My machine's an STE, 2.06, 4MB. Stock in all other respects.

Daft question: does the card need to be Win32 formatted/partitioned beforehand or is there anything else (parameter wise) I need to be aware of?

I should have taken a backup image of the card first ;)

@exxos any chance you could put the SD card image somewhere so I can grab it?

Cheers

I didn't produce them @dad664npc did.

I'm getting my sh*t together - bbansolutions.co.uk - a work-in-progress like everything else :shock:
Tell me what you want to see there

If you could make the SD card image available for download that would be great :dualthumbup:

Ah it's already there - thanks :dualthumbup:

I got number 0004!

While using an STe, unfortunately when I try to write anything to the disk I get this error. GEMBench, Frontbench will all happily load at least.

H5 with tf536 doesn't seem to want to work with it...

While I said all was working well yesterday, I didn't try to write anything. I'm getting the same error when writing. Reads are fine.

Perhaps I need the bus pullups? I have the C398739-001A DMA

Just tried it in my FM and I could create folders fine

Unfortunately if your ATARI ST has a bad DMA chip then anything plugged in the ACSI bus isn't going to work. The HDC was tested on an STFM which does not have any board modifications and worked just fine. But that could of course just be luck. STE's should be a little more robust as far as the ACSI interface goes as they have a LS245 chip in-between . exxos can explain all the DMA problems

[exxos]

I have only tested the -38 DMA with the HC CPU in a STE. With my booster the 001A DMA worked worse, but don't know if that's the case without the booster yet. I didn't expect many people to have the supposed "good DMA" so didn't make testing yet.

I had little trouble with the H5 other than some issues with the HDC which were fixed in the firmware.

I'm going to try adding bus pullups sometime over the weekend. Sounds like a longshot but you never know :crossed2:
