10:34 PM Feature #76: Merge down to trunk
Tried building with riscv and the firmware size dropped from 37KB to <32KB. Which is great! So might need to reactiva... foft

Building the mcc216 with this latest firmware + plumbing changes. Realized the scandoubler will not fit in the memory... foft
09:31 PM Feature #79: SDHC and SDXC support
Tested my 32GB card from the Pandora and its working. This is the maximum supported by the Chameleon menu right now. foft

I think chameleon 1 and chameleon 2 are good. firmware_eclaire is running on them and also on the eclaire.

07:57 PM Feature #80: Read roms from spi flash on chameleon
Jens confirmed that they are all using the same flash chip.
Backport looking good to me...

10:56 PM Feature #80: Read roms from spi flash on chameleon
Same flash chip as I'd used on the Eclaire... Pretty luck! Anyway the backport seemed to work without issue so far, j... foft
10:35 PM Feature #80: Read roms from spi flash on chameleon
Working on the backport now chameleon 2 is working well... foft
10:34 PM Feature #78 (Closed): Get chameleon v2 working
Chameleon 2 is working pretty well.
Moving onto Chameleon 1 backport then will check all other cores work...

11:31 PM Feature #78: Get chameleon v2 working
Well added a synchronizer on ba and also added a when others clause to put it back into a proper state.
Should pro...

11:19 PM Feature #78: Get chameleon v2 working
I wonder if ba needs a synchronizer or something like that? foft
11:16 PM Feature #78: Get chameleon v2 working
Got a state capture when its working, goes through states as normal.
When it stops, no states are active!

11:13 PM Feature #78: Get chameleon v2 working
Re c64 keyboard, the state machine reading it appears to get stuck and just reads DC01 repeatedly?? foft
10:52 PM Feature #78: Get chameleon v2 working
Now behaving again, think Chaco had got confused and was doing weird stuff. foft
10:41 PM Feature #78: Get chameleon v2 working
Getting some weird behaviour tonight - cores not starting etc. Unclear what the issue is... foft
10:25 PM Feature #78: Get chameleon v2 working
Tried it in the c64. Keyboard works, but only sometimes! Need to work out why. foft

10:29 PM Feature #78: Get chameleon v2 working
Did the keyboard plumbing. Seems to work - okish. Though can save some bytes by doing this part in vhdl I think, so m... foft
10:09 PM Feature #78: Get chameleon v2 working
Of course one more important step: try it in a C64! foft
09:54 PM Feature #78: Get chameleon v2 working
Picked up the slot from the micro. Computed the location of the rom. I added 256kb of blank space first to aligned to... foft
09:49 PM Feature #80: Read roms from spi flash on chameleon
Got this working as part of the port on chameleon 2.
Need to apply the same updates to chameleon 1.

09:26 PM Feature #78: Get chameleon v2 working
OK, that works foft
09:21 PM Feature #78: Get chameleon v2 working
I should be passed the slot by the microcontroller, but since I'm using sof at the moment that clearly isn't working.... foft

10:33 PM Feature #78: Get chameleon v2 working
I can't see which flash chip is used, guess I'll just wire it up and try reading the id! foft
10:27 PM Feature #78: Get chameleon v2 working
+ 3 byte header with binary length (when flashing rpd) foft
10:20 PM Feature #78: Get chameleon v2 working
I have a 1MB slot. The core itself takes about 350KB compressed. So lets say we have 1/2 MB conservatively to store r... foft
10:09 PM Feature #78: Get chameleon v2 working
Testing video mode setting (only basic stuff, rgb/vga, no pll reprogramming) and looking ok.
Tested 3rd/4th joystick...

Now trying to plumb in eclaire firmware 'properly'. e.g. settings/os load/save, video settings, 800 mode etc. Got it ... foft
09:56 PM Feature #78: Get chameleon v2 working
Added back the 'return to menu' foft
08:04 PM Feature #78: Get chameleon v2 working
Still don't understand what the logic analyzer tells me, I'm guessing its an optimization since the hdl is pretty hig... foft
07:45 PM Feature #78: Get chameleon v2 working
Weird thing in chameleon_cdtv_remote, the timer counts when ena_1mhz is high AND halfway between. So is running at 2x... foft

Trying to get the ir remote working, should 'just work' since its enabled in chameleon io2 but ... it doesn't foft
04:53 PM Feature #78: Get chameleon v2 working
Haha, this was a known issue on the old version of the chameleon (in many cores) and this one too... foft
03:48 PM Feature #78: Get chameleon v2 working
Different sd card worked, think its a card re-initialization issue... foft
