FO 10:07 PM Bug #64: Pokey pdm timing incorrect: Tried a 1 cycle and a half cycle delay on the input to the xor. Neither are seeming quite right, but 1 cycle delay is closest... foft
FO 08:21 PM Bug #64: Pokey pdm timing incorrect: Phaeron got a scope on it:

Looks to be high pass filter propagation delay related. foft

FO 09:52 PM Bug #66: Odd flash behaviour on new boards: Gathering ids on other boards in case I need to switch on that: [[Flash_chip_by_board]] foft
FO 09:49 PM Bug #6: HDMI audio poor quality: # Is the time between this always the same? If so can dIs the sound quality poor because I removed the divide?
# If so, does the divide happen at a consistent period? If so I can scale/multiply then divide by power of two.
# Or is the ... foft

FO 09:14 PM Warning: flash chip on new boards: I have not received my new board yet so have yet to test the new flash chip (S25FL127SABMFV000). So, unless you have a USB blaster, I suggest not using any of the flash settings until I ensure it is stable.
I should add that if you do... foft
FO 09:11 PM Bug #66 (Closed): Odd flash behaviour on new boards: Ensure that the new flash chip is stable with the existing firmware strategy. It has some hybrid 64k/4k sector option or a 256k sector option. From Panos' reports it seems to behave well when I treat it as a 256KB sector device and oddly... foft
FO 03:28 PM V21: Not so many features on this version, but I think it is a worthwhile one!
* RPD flashing support
So what is it? Well it allows flashing a new core from the sd card. So its possible to upgrade without a USB blaster.
So now there... foft

FO 06:31 AM Feature #65: Implement ATA to SPI bridge: Above was info from flashjazzcat on the forum foft
FO 06:30 AM Feature #65: Implement ATA to SPI bridge: I need to prepare a document outlining the minimum requirements of IDE emulation since I'm explaining the same thing in multiple locations at the moment. ;) Absolute minimum requirement is the 8 basic IDE registers, and it's useful to be... foft

FO 09:25 PM New boards: The new boards are ready and shipped. So I'm hoping to see more activity here when they start to arrive. Also now this is done I expect to go back to some firmware development again, so we can get some new 2018 features...
As a remind... foft

http://atariage.com/forums/topic/244946-using-pulse-density-modulation-for-8-bit-pcm/page-3#entry4025673
So white on black is currently good, while black on white should be better. Seems related to the rise/fall times... foft
