All right! Primitives using HCLK (OSER4/8/10/VIDEO IDES4/8/10/VIDEO) worked on #tangnano20k Himbaechel-#gowin. On the picture, just testing the last IVIDEO :)

so for today - deal with the high-speed clock for IO #tangnano20k.

If #riscv works on #tangnano20k, then simpler things will probably work. But I can't rely on luck, so I check everything. Here is the ELVDS 😃

Ladies and gentlemen, Himbaechel-#gowin supports #tangnano20k to the extent necessary for #riscv to function correctly (example attosoc). Hooray!

Oh! The #Tangnano20k board, kindly donated by SipeedIO, has arrived in the big city!😀
It will be necessary to go to the city and pick it up in the coming days.
Truly a good day.🎇

IVIDEO primitive started working and with that I close the topic of small serialization primitives and move on to large OSER16 / IDES16.
These monsters take up two cells each. It's a bit unfortunate that #tangnano20k and the company don't have such primitives, so the main work will be to accurately implement the GW1N series.
