Any plans to use rk3399 for a 2nd revision of the eoma68 standard? or any alternative arm processor? Since risc-v is maybe 3+ years out of the way?
yes. bear in mind it's around USD $5k-10k per design effort. i *may* be able to recover the RK3288 PCB i did. the RK3399 would be nicer.
Although it's not a 64-bit CPU and is MIPS-based not ARM-based, wasn't the JZ4775 board almost done?
pretty much - i just couldn't get beyond u-boot, as i had put a 24mhz XTAL in rather than a 48mhz, and i couldn't get the PLLs right to get beyond the SPL loader.
And didn't it have 2GB RAM already, before the A20 2GB RAM (and HDMI) rework effort?
yes.
Of course there is the software distribution issue (if you want FSF endorsement), but there seems to be some demand for similar products.
I follow the Dingoonity scene at a distance and although there is plenty of gadget chasing - people seem to throw themselves at random handhelds with poor screens and obsolete JZ variants - there are some that still wonder about successors to the GCW-Zero handheld or even getting one of the original ones, particularly as it seems that not everyone managed to receive one in that campaign. The enthusiasm is presumably something to do with MIPS-based stuff being used in various consoles of a certain era.
ok - well, i've still got 2 of the cards around somewhere, and i can order some 48mhz XTALs: i have a heat gun so should be ok to put them in.
i have no idea what kinds of volumes to expect.
