11:31 PM Feature #76: Merge down to trunk: Experimenting with replacing the menu with a simple structure/code approach, should cut code size somewhat. foft

09:53 PM Feature #76: Merge down to trunk: -flto gets me to 33244 foft
09:39 PM Feature #76: Merge down to trunk: That was with 64-bit riscv, switched to the 32-bit version and its bigger: 39512 foft

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

10:45 PM Feature #76: Merge down to trunk: freezer 1024 1
antic 1536 1
scandoubler1 14600 2
scandoubler2 14600 2
zpu rom 327680 40
zpu ram ... foft
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... 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

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... foft
07:59 PM Feature #80 (Closed): Read roms from spi flash on chameleon: foft
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

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... foft

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... foft
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! foft
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. foft

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
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 possi... 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... foft
