10:29 AM Feature #76: Merge down to trunk
Perhaps a state machine to do the in request too, then I do not even need to call poll. foft
10:28 AM Feature #76: Merge down to trunk
Perhaps I could even write byte stream to a hardware buffer and have regs for axis offset, axis type (signed/unsigned... foft
10:26 AM Feature #76: Merge down to trunk
Need to save 6k. Lots of complexity in the USB, largely for supporting the custom mcc joysticks. I could comment them... foft

Probably split into too many functions, adding function call overhead...
Anyway should probably target some of th...

Experimenting with replacing the menu with a simple structure/code approach, should cut code size somewhat. foft

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

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.

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

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!

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

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

Got this working as part of the port on chameleon 2.
Need to apply the same updates to chameleon 1.
