FO 10:13 PM Feature #62: Store settings in spi flash: On some cyclones the active serial pins can be directly used as IO. I tried that on here (cyclone v) but it didn't work, however it should be possible using the serial flash loader. This is what is internally used when programming via ji... foft

FO 09:24 AM Feature #62 (Closed): Store settings in spi flash: Read/write settings from the flash chip, with override from sd.
Want to check this works before new boards. foft

FO 09:09 PM Bug #47 (Closed): CORE 13 - Paddle, Touchtablet issues: foft
FO 09:08 PM Bug #47: CORE 13 - Paddle, Touchtablet issues: In the next run of boards we are added a variable resistor to allow adjusting the level the paddle detector uses.
For old boards, use a decent PSU! foft
FO 09:06 PM Feature #24 (Closed): A board with Atari SOUL!!!! (ROM in block ram support): Added basic support, see related issue.
I still plan to do the flash reading later. foft
FO 07:56 PM Feature #24 (In Progress): A board with Atari SOUL!!!! (ROM in block ram support): foft
FO 09:05 PM Feature #37: SD card insertion support: Confirmed that SD detect works.
Added primitive insert/eject support. Its kind of crap, but it works...
Boot with no SD card means -> 320KB compy 1x, HDMI if connected, VGA if connected, otherwise RGB 15KHz. NTSC (more monitors com... foft
FO 07:57 PM Feature #37: SD card insertion support: Another place we need to check hardware before new boards... foft
FO 07:56 PM Feature #37 (In Progress): SD card insertion support: foft
FO 07:55 PM Feature #14 (Closed): Svideo core for first prototype: I don't see composite and svideo as core outputs, much worse quality even when perfectly done. I'm pretty happy with the current state, sometimes the TV controls need adjusting a little but that isn't a big problem. foft
FO 07:53 PM Bug #56 (Closed): Galaxian Cartridge crash: Working fine on recent cores foft

FO 09:14 PM Feature #12 (Closed): Set up redmine backups!: foft
FO 09:14 PM Feature #12: Set up redmine backups!: My second disk died before I moved it to the NAS. Never mind though, recovered the data. Now backup is to my nas since I do not have a 2nd disk! foft
FO 09:13 PM Bug #17 (Closed): NTSC crashing on some builds: On second thoughts... closing until we see it again. foft
FO 09:11 PM Bug #17: NTSC crashing on some builds: Not seen this for months, think it was an issue around this time that has been fixed. Marking as normal priority for now. foft
FO 08:51 PM Feature #7: Implement I2C vga/hdmi support: Added to the video settings 'VGA connected' and 'HDMI connected' which look for the start of the DDC sequence '00FF' foft
FO 08:25 PM Feature #7: Implement I2C vga/hdmi support: Setting back to normal since the hardware side is working fine. foft
FO 08:25 PM Feature #7: Implement I2C vga/hdmi support: HDMI is working too... “00 FF FF FF FF FF FF 00 10 AC … foft
FO 08:23 PM Feature #7: Implement I2C vga/hdmi support: VGA is working... receiving “00 FF FF FF FF FF FF 00 10 AC …"
Now for HDMI foft
FO 08:00 PM Feature #7: Implement I2C vga/hdmi support: I had the pin assignments backwards. I can now write 4/5 to the control register and read it back. This should be channel select.
Next up... checking that what I write makes it to the VGA and HDMI port. I guess I could try speaking t... foft

FO 09:38 PM Feature #7: Implement I2C vga/hdmi support: Looking on signaltap looks like slave reads of the control register are not working. Hmmm. foft
FO 09:36 PM Feature #7: Implement I2C vga/hdmi support: Picoscope has i2c debugging and linux drivers:-) Installed them and will connect that up and take a look tomorrow. foft
FO 09:28 PM Feature #7: Implement I2C vga/hdmi support: Writing some code to say:
select channel1
read selected channel
write to random slave on channel1
select channel0
read selected channel
write to random slave on channel0
Might be working, but need to work out how to check...... foft

Congrats! ;-) sadosp
FO 08:49 PM Feature #15: Implement programmable PLL: OK, confirmed this chip is working. I programmed it over i2c and am now getting two different clocks output on CLK0 and CLK2 - 10MHz and 30MHz as I set up in the clk generator software.
Going to mark this back as normal priority since I... foft

FO 09:58 PM Feature #15: Implement programmable PLL: Been adding i2c to the zpu. Mostly working I think, a few timing issues to solve. foft

FO 09:59 PM Feature #15: Implement programmable PLL: To do this I need to add i2c support to the ZPU. I'm out of ROM space without easy fixes. There is actually quite a lot space even on the EBA2, so adding 8K extra for now. Currently it was using bit 15 to decide rom/ram. I made it use 14... foft
AD 09:24 PM Feature #15: Implement programmable PLL: Going to power this up urgently before new boards made, to check hardware side is fine. admin
FO 09:23 PM Feature #15: Implement programmable PLL: Attached the note on how to program manually (without clock builder help) foft
FO 09:22 PM Feature #15: Implement programmable PLL: Attached header file for programming clk0->10MHz and clk1->30MHz.
These are generated with clock builder pro, downloaded from ic vendor web site. foft
AD 09:25 PM Feature #7: Implement I2C vga/hdmi support: Going to at least check this chip is wired properly before the new boards are ordered admin
AD 09:24 PM Bug #18 (Closed): Power on Switch: Panos fixed this for the next run admin

FO 11:12 AM Feature #3: High resolution antic support: So antic output looks near perfect. Some blue blobs on the left which I need to investiate. The shift register is clear so not sure where they come from! foft
FO 11:11 AM Feature #3: High resolution antic support: Still not onto GTIA! Doing some debugging on the non display parts of antic output. Improved my visualation tools to help with this. Here we have:
i) DMA clock (4 bits)
ii) Display shift reg
iii) AN0-2 output
iv) GTIA colour (+ some ... foft
