FO 10:28 PM Feature #76: Merge down to trunk: Building the mcc216 with this latest firmware + plumbing changes. Realized the scandoubler will not fit in the memory at the same time as this larger firmware, arg! foft
FO 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

FO 08:00 PM 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 back to some other targets soon. foft
FO 07:59 PM Feature #80 (Closed): Read roms from spi flash on chameleon: foft
FO 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... foft

FO 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, just some plumbing. foft
FO 10:35 PM Feature #80: Read roms from spi flash on chameleon: Working on the backport now chameleon 2 is working well... foft
FO 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... foft

FO 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 probably discuss with Peter to see if there is a better fix. foft
FO 11:19 PM Feature #78: Get chameleon v2 working: I wonder if ba needs a synchronizer or something like that? foft
FO 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! foft
FO 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
FO 10:52 PM Feature #78: Get chameleon v2 working: Now behaving again, think Chaco had got confused and was doing weird stuff. foft
FO 10:41 PM Feature #78: Get chameleon v2 working: Getting some weird behaviour tonight - cores not starting etc. Unclear what the issue is... foft
FO 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

FO 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 might do that. foft
FO 10:09 PM Feature #78: Get chameleon v2 working: Of course one more important step: try it in a C64! foft
FO 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 a block (this board has 64kb but some might be 256kb...). Now loading and saving is working well.
Docs on the chamel... foft
FO 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. foft

FO 09:26 PM Feature #78: Get chameleon v2 working: OK, that works foft
FO 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. The firmware is currently hardcoded to 0x200000. Which is slot 2 (but wrong half of it!). Will just give that a spin to... foft
FO 09:18 PM Feature #78: Get chameleon v2 working: 1c7018, which is...
EN25QH128A
datasheet attached
So, 64k blocks (erase by d8 as currently used, sector also possible)
Should just work, once I change the addresses. foft

FO 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
FO 10:27 PM Feature #78: Get chameleon v2 working: + 3 byte header with binary length (when flashing rpd) foft
FO 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 roms etc. The standard eclaire settings saving takes 192KB.
I guess I can also allow the rpd flashing support.
So... ... foft
FO 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 joysticks in atari800 mode. Got them working but had to change/fix a few small things.
Want to try out flash chip next... foft

FO 10:51 PM 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 running as far as menus/drive emulation. Had a bit of difficulty at first because I was doing some binary editing to add... foft
FO 09:56 PM Feature #78: Get chameleon v2 working: Added back the 'return to menu' foft
FO 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 high level.
In any case solved the actual issue by adding a synchronizer on ir_data. Working just fine now. foft
FO 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 the expected rate. Its not clear why. foft

FO 04:54 PM 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
FO 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
FO 03:48 PM Feature #78: Get chameleon v2 working: Different sd card worked, think its a card re-initialization issue... foft

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

FO 10:29 PM More cases!: wt808 (of mini 5200 fame: http://atariage.com/forums/topic/185369-compact-5200-system/) has designed a selection of cases for the EclaireXL mini. Several people are still tweaking/adjusting them though they are already looking good. He h... foft
