FO 11:21 PM Feature #76: Merge down to trunk: Released a first cut of them here http://www.64kib.com/autobuild/20190622/

FO 09:59 PM Feature #76: Merge down to trunk: That is really the main existing boards that worked well. Might do a release build with this state.
After which these remain...
# papilio duo - simple port. Since its xilinx will need to fix the fifo (using Intel IP...)
# fpgaarcade... foft
FO 09:50 PM Feature #76: Merge down to trunk: mist 800xl is working. Skipping mist 5200 since it has been converted into a zpu-free core by György foft
FO 09:06 PM Feature #76: Merge down to trunk: mcctv 800xl and 5200 working foft

FO 10:31 PM Feature #76: Merge down to trunk: mcc_5200 seems fine (minimal changes here). Next up mcctv... Tried to merge diff and quite a lot of failed hunks, will have to do manually. foft
FO 08:20 PM Feature #76: Merge down to trunk: Saved some memory in USB and also saved some memory by disabling flash. Now fits in 36K on MCC, with a little space. Will do for this board, can save the things I thought of above for later! foft

FO 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
FO 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), button offset. Then poll becomes just sending an in request and writing to this hardware buffer. init becomes initial... foft
FO 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 but its mostly for the MCC that I have memory issues so I want to support the official joypads!
Idea: Really USB pol... foft

FO 10:52 PM Feature #76: Merge down to trunk: Probably split into too many functions, adding function call overhead...
Anyway should probably target some of these big items:
nm --print-size --size-sort --radix=d ECLAIREXL.elf | less
0007457 00000527 T tfp_format
00012850 0... foft
FO 10:31 PM Feature #76: Merge down to trunk: Haha, working and much neater, but 300 bytes more foft

FO 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

FO 09:53 PM Feature #76: Merge down to trunk: -flto gets me to 33244 foft
FO 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

FO 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 reactivate the zpu->riscv plan... foft

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
