FO 09:19 PM EclaireXL Developer: RE: Use a real floppy drive?: It might be worth starting from a simple setup. i.e. test a drive by itself as D1 without the internal sdrive. Before heading towards the full on 'n' external drives in combination with sdrive. foft

FO 09:44 PM EclaireXL Bug #67: Pokey two tone timing problem: I found if I pokey 53775,11+128 on the Atari then it matches the Eclaire output. Unfortunately forcing the serious output on eclaire to 1 or 0 does not change anything. Still its something to go on! foft

FO 10:03 PM EclaireXL Bug #67: Pokey two tone timing problem: So, errr identical then! Going to have to think about this one...
B is Atari, A is EclaireXL.

FO 09:57 PM EclaireXL Bug #67: Pokey two tone timing problem: Nope, seems to be some interaction with the noise filtering. I wonder if the delay also needs applying to the pulse from the timer, that then hits the noise filter. foft
FO 09:27 PM EclaireXL Bug #67: Pokey two tone timing problem: A 2 cycle delay on the reset fixes both the 4 cycle and the 9 cycle case.
Now to check this specific example! foft
FO 12:23 PM EclaireXL Developer: RE: Use a real floppy drive?: Did you get it working? foft

FO 09:55 PM EclaireXL Bug #67: Pokey two tone timing problem: I was concerned that my clocks were off at first since I was running in VGA mode, but that changes vsync slightly (50Hz vs 4.86Hz) which of course also impacts audio frequency:-) Debugging in RGB mode gives a perfect match. foft
FO 09:54 PM EclaireXL Bug #67: Pokey two tone timing problem: Been measuring cases on the scope...
Confirmed the extra cycle delays described in that forum post on my 600XL. Confirmed missing on the EclaireXL implementation. foft

FO 09:35 PM EclaireXL Developer: RE: Use a real floppy drive?: One thought, the default OS is high speed patched and perhaps that conflicts with your drives. You could try using the standard one too. foft
FO 09:24 PM EclaireXL Developer: RE: Use a real floppy drive?: Just been playing for 20 mins with aspeqt, my real 1050 and the internal drive.
Afraid I can't reproduce this. I suspect a bad SIO cable perhaps?
That said, what kind of drives are you using? I wonder if they are using different s... foft
FO 07:54 AM EclaireXL Developer: RE: Use a real floppy drive?: If you take the disk out of sdrive 1 does it then work? foft

FO 09:09 PM EclaireXL Feature #65: Implement ATA to SPI bridge: What is used in set features?
0xef set features, then set feature 1 + lba mode?
Think this can probably be ignored. foft
FO 09:04 PM EclaireXL Feature #65: Implement ATA to SPI bridge: Identify:0xec
0->SCNT,SNUM,CYLL,CYLH
0xa0->HEAD
0xec >STAT
read stat -> if 0 then does not exist! Then wait for BSY to clear and RDQ to set.
read data -> 512 bytes
See above for the interesting bytes from this. foft
FO 08:53 PM EclaireXL Feature #65: Implement ATA to SPI bridge: https://wiki.osdev.org/ATA_PIO_Mode
Probably want at least DRQ(3/ 1=ready), RDY(6 /1=good) and BSY(7/ 0=not busy) in the status reg foft
FO 08:40 PM EclaireXL Feature #65: Implement ATA to SPI bridge: Some links..

Simple read seems to be:
sector address-> 4 lba regs with $e0 in high part
scnt-> 1
stat-> cmd

FO 08:24 PM EclaireXL Feature #71 (New): Add support for user firmware updates: Add support to load new firmware from sd card. Then it can be applied immediately for testing or flashed.
I'd like this to make it easier to build/test new firmware. foft

FO 08:12 PM EclaireXL Feature #70: Add hotkeys for video mode selection: Added something simple...
Press F11 to go to menu.

D: DVI
H: HDMI
V: VGA
S: SVIDEO
C: COMPOSITE
Z: Toggle composite sync

FO 08:14 PM EclaireXL Core v24: Very small change since I've realized how annoying the video mode selection is (i.e. find sd card, copy on settings...)
Added some hotkeys. To use them go to the F11 menu and then press:
P: PAL

R: RGB
A: SCANDOUBLE
D: DVI... foft
