- FO 09:14 PM Feature #12 (Closed): Set up redmine backups!
- 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!
- FO 09:13 PM Bug #17 (Closed): NTSC crashing on some builds
- On second thoughts... closing until we see it again.
- 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.
- 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'
- FO 08:25 PM Feature #7: Implement I2C vga/hdmi support
- Setting back to normal since the hardware side is working fine.
- 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 …
- 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 - 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...

- 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.
- 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.
- 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...... - SA 09:15 PM Feature #15: Implement programmable PLL

Congrats! ;-) - 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...

- 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.
02/04/2018
- 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...
- 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.
- FO 09:23 PM Feature #15: Implement programmable PLL
- Attached the note on how to program manually (without clock builder help)
- 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. - 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
- AD 09:24 PM Bug #18 (Closed): Power on Switch
- Panos fixed this for the next run
02/02/2018
- FO 10:30 PM v17 out and new boards
- The high-res antic work is still ongoing but I think this is now stable enough for general use.
* High res antic support (2x and 4x colour clock)
* High res antic disables pbi (so works at 1x cpu)
* Sophia style 2 colour high res (p...

- 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!
- 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 ...

- FO 09:26 PM Meltdown
- I upgraded my server for the meltdown patch and my hard drive took the opportunity to die. So that was fun...
Not much progress on this side. I played around in WUDSN with programming the new highres modes which was quite fun. They ar... - FO 08:54 PM Feature #2 (Closed): PBI support
- Closing, seems to be working well. At least on all the devices I have!
- FO 08:51 PM Feature #26 (Closed): PS/2 keyboard
- These adaptors are just wiring. The keyboard detects if it works in USB or PS2 mode. It can be that the keyboard detects the wrong mode.
- FO 08:48 PM Bug #45 (Closed): CORE10 - IDE2+ SDX not working
- Closed since Nir confirmed this behavior on original hardware
- FO 08:45 PM Bug #43 (Closed): Core 10 - IDE2+ Menu does not show when powering the computer with START key pressed
- Marking as closed since the IDE2+ itself seems to work. Would be nice to test the black box and MIO but if someone does and finds an issue that than be raised elsewhere.
