I seem to have solved this odd error issue now..

Oddly the 720K drive which was working, wasn't working this morning. One of those red-herrings which throw you off!

So I have delayed ST_AS by another CPU clock cycle.. So now I have..

Code: Select all

AS1.CK = CLK8;
AS1.D = CPU_AS # !ST_BGACK ;

AS2.CK = CLK16;
AS2.D = AS1 # CPU_AS # !ST_BGACK  ;  // have to use this to prevent floppy format issues

ST_AS.AR = !RESET;
ST_AS.CK = CLK16;
ST_AS.D = AS2 # CPU_AS # !ST_BGACK ;   
ST_AS.OE = ST_BGACK   ;   

Before I was only using AS1 for the ST_AS.D input, now its AS2 and the issue seems to be resolved 8-)

Crappy cam video .. ( I can't hold the cam and use keys to move the mouse at the same time!)

What's been annoying me is I have no output to decode ROM.. Now I have the new dualtos boards with TOS104/206, its bodge wire time on the SEC's PLD...

Great work! Out of interest, I am assuming that error happens on the earlier accelerators too? I am sure I've seen that error when trying to format floppies with the 16Mhz v1 board.

Shouldn't happen on earlier versions because they switch back to 8MHz on any bus activity. These new SEC boosters don't, they run at 50MHz all the time, so a bit more complicated to get going than the earlier gen boosters.

Just installed the v2.3 booster and TOS board and I'm having same disk problems. Reading data seems to have the same problem. Same from a gotek drive. I have a IDE controller board and Marpet with 4Mb also installed. Reading from flash/IDE seems fine.

Started adding in the ROM decoding code..

First run..

Need to figure out why TOS206 isn't working next :roll:

Tighter control of ROM access.. pretty much maxed out now...

With the blitter enabled...

It runs super sweet :)

EDIT:

Putting the blitter back in is causing that floppy error thing again.. :roll: So I have another issue to investigate..

Right so this is annoying.. It wasn't the blitter it seems which made the format go wonky, but my new ROM code :roll: I still not figured out why TOS206 isn't working yet.. but obviously bypassing GLUE's ROM decoding for "fast decoding" has brought back the floppy error again :roll:

I also found a small "bug" that if blitter access ROM, the logic can't issue ST_DTACK, but will fix that next version anyway.

After faffing about all day with this, It all seems to work fine other than that initial error when formatting a floppy. The diagnostic cart and FCOPYIII work fine.. So I can only assume it's some "bug" in TOS itself.. I have asked EMUTOS guys if they have any clues about it...

I've not been able to figure out TOS206 not working either yet. Its the same code as my V2.X boosters and same ROM board...

Oddly GLUE doesn't like being isolated during ROM access. The V2.X boosters isolated GLUE, but those were switching to 8MHz a lot of the time, so likely why I only just started seeing more problems.

GLUE isolation seems to be work now.. I think I must have had a typo somewhere in my code as I reverted back to a previous versions and made the changes again :roll:

So the PLD is totally in control of ROM decoding and DTACK.. just 206 isn't working at all... I know the ROM itself is good as works on V2.3 booster.. the code in the PLD is the same as the V2.3 booster...

I could only think there is a bad addressline on the PCB preventing 206 from booting, but metered the addressbus out to the PLD and CPU and seems OK...
