10:34 PM EclaireXL 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

10:28 PM EclaireXL Feature #76: Merge down to trunk: Building the mcc216 with this latest firmware + plumbing changes. Realized the scandoubler will not fit in the memory... foft
09:31 PM EclaireXL 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

08:00 PM EclaireXL Feature #76: Merge down to trunk: I think chameleon 1 and chameleon 2 are good. firmware_eclaire is running on them and also on the eclaire.
Heading... foft
07:59 PM EclaireXL Feature #80 (Closed): Read roms from spi flash on chameleon: foft
07:57 PM EclaireXL 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... foft

10:56 PM EclaireXL 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 EclaireXL Feature #80: Read roms from spi flash on chameleon: Working on the backport now chameleon 2 is working well... foft
10:34 PM EclaireXL 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... foft

11:31 PM EclaireXL 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... foft
11:19 PM EclaireXL Feature #78: Get chameleon v2 working: I wonder if ba needs a synchronizer or something like that? foft
11:16 PM EclaireXL 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! foft
11:13 PM EclaireXL 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 EclaireXL Feature #78: Get chameleon v2 working: Now behaving again, think Chaco had got confused and was doing weird stuff. foft
10:41 PM EclaireXL Feature #78: Get chameleon v2 working: Getting some weird behaviour tonight - cores not starting etc. Unclear what the issue is... foft
10:25 PM EclaireXL 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 EclaireXL 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 EclaireXL Feature #78: Get chameleon v2 working: Of course one more important step: try it in a C64! foft
09:54 PM EclaireXL 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 EclaireXL 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. foft

09:26 PM EclaireXL Feature #78: Get chameleon v2 working: OK, that works foft
09:21 PM EclaireXL 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
09:18 PM EclaireXL Feature #78: Get chameleon v2 working: 1c7018, which is...
EN25QH128A
datasheet attached
So, 64k blocks (erase by d8 as currently used, sector also possi... foft

10:33 PM EclaireXL 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 EclaireXL Feature #78: Get chameleon v2 working: + 3 byte header with binary length (when flashing rpd) foft
10:20 PM EclaireXL 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 EclaireXL 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... foft

10:51 PM EclaireXL Feature #78: Get chameleon v2 working: 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 EclaireXL Feature #78: Get chameleon v2 working: Added back the 'return to menu' foft
08:04 PM EclaireXL 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 EclaireXL 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

04:54 PM EclaireXL Feature #78: Get chameleon v2 working: Trying to get the ir remote working, should 'just work' since its enabled in chameleon io2 but ... it doesn't foft
04:53 PM EclaireXL 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 EclaireXL Feature #78: Get chameleon v2 working: Different sd card worked, think its a card re-initialization issue... foft

10:46 PM EclaireXL Feature #78: Get chameleon v2 working: Running NUMEN as a little test ;-) foft
10:46 PM EclaireXL Feature #78: Get chameleon v2 working: Fixed issue (i) foft
