Forth Co-Processor<a href="https://mastodon.social/@olimex" class="u-url mention" rel="nofollow noopener noreferrer" target="_blank">@olimex</a> I think that both your board and the <a href="https://mastodon.social/tags/picoice" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#picoice</a> are fantastic. The combination of an <a href="https://mastodon.social/tags/RP2040" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#RP2040</a> and an <a href="https://mastodon.social/tags/FPGA" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#FPGA</a> is both powerful and inexpensive. I think I prefer your <a href="https://mastodon.social/tags/gatemate" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#gatemate</a> fpga, but I prefer their sdk. <a href="https://github.com/tinyvision-ai-inc/pico-ice-sdk" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://github.com/tinyvision-ai-inc/pico-ice-sdk</a> I like your ps2 and vga ports but I would prefer 2 usb host ports. Which pico-ice also does not have. I like that they have two flash memories, one for the rp2040, and one for the fpga. All we can do is to choose between the boards that are available to us.

Forth Co-ProcessorKonilo looks really interesting. A big brother to <a href="https://mastodon.social/tags/uxn" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#uxn</a>. UXN had 8bit memory cells. Like the discontinued z80. 32 bit memory makes much more sense to me.

Getting the initial J!Sc running on a non supported board looks quie difficult because of all of its additional features.

TicktokIf anyone is playing with the new <a href="https://fosstodon.org/tags/picoice" class="mention hashtag" rel="tag">#picoice</a> fpga devboard. There might be a bug in the firmware for transferring uf2 bitstream to the ice40. I was unable to use apio upload or dragging a uf2 into the pico-ice drive. only use `dfu-utils -d 1209:b1c0 -a 1 -D firmware.bin` worked for me. Or using the ice-makefile-blinky example, which automates the same command.<a href="https://discord.com/channels/644405956494753803/985342148884987934/1158433617299652798" target="_blank" rel="nofollow noopener noreferrer" translate="no">https://discord.com/channels/644405956494753803/985342148884987934/1158433617299652798</a><a href="https://fosstodon.org/tags/fpga" class="mention hashtag" rel="tag">#fpga</a> <a href="https://fosstodon.org/tags/ice40" class="mention hashtag" rel="tag">#ice40</a> <a href="https://fosstodon.org/tags/rp2040" class="mention hashtag" rel="tag">#rp2040</a>

Forth Co-ProcessorHere is my best estimate as to when the Hana processor will ship. Maybe the word guess is more accurate than estimate.

Forth Co-ProcessorSo although it uses the <a href="https://mastodon.social/tags/ICE40" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#ICE40</a>, it is by a different manufacturer than the <a href="https://mastodon.social/tags/picoice" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#picoice</a>, so the pins that connect the USB chip to the FPGA chip may be different, in which case it will need a different bitstream.
