Siped Tang Console is an FPGA dev board that can also be used as a retro console with downloadable NES, SNES, Game Boy, and Amiga cores, among others. It sells for $69 and up ($99 and up for a higher-performance version). #Sipeed #FPGA #RetroGaming #SipeedTangConsole https://www.cnx-software.com/2025/05/27/sipeed-tang-console-a-gowin-gw5ast-gw5at-board-with-60k-or-138k-lut-for-fpga-development-and-retro-gaming/

Has anyone out there in Fedi-world ever used the #Sipeed M1s DOCK (I don't know why it's in all-caps but it is) dev board?

I bought a couple of them because they were cheap, and now naturally I need to decide what to do with them.

They are orders of magnitude more powerful than my usual go-to, the #ESP8266. Supposedly, they will even run 'real' Linux.

They use the Bouffalo Labs BL808, so it looks like this is the SDK?

Any tips, ideas, success stories?

So. Zork didn't fit into memory - even on RT-11 it took 500K and required a disk drive, so we demonstrate the work of Cortex-M3 with UART built into #Tangnano4k on another text game:).

#Apicula has learned how to use the ARM processor built into the #Tangnano4k!

I thought that to demo a whole processor of a simple LED would be kinda uncool, so this bitbang SPI to E-inc display!!!

The Sipeed Lichee Console 4A is the first RISC-V mini laptop available, and while it's not particularly useful as a general-purpose computer, it's a fairly affordable option for those looking for a RISC-V development and testing platform. https://www.cnx-software.com/2024/01/29/lichee-console-4a-risc-v-devkit-testing-benchmarks-features-debian-12/ #RiscV #MiniLaptop #Sipeed #SipeedLicheeConsole4a #SipeedLM4A

Now that it’s clear to me how these primitives work, let’s proceed to the funniest stage: we check the functionality of the primitive on a specific board - cross out the entries in the table, move on to the next combination. When correcting code, we check everything from the very beginning

Yey! The Dual Port BSRAM primitive began to work in #apicula.
What is happening: the video memory is a BSRAM with two ports, most of the time the picture is changed by writing to port A, displayed on the screen by reading through port B, but when you press the button, the entire video memory is written to zeros through port B. That is, everything is cool!

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

Here I am a fool - I did not explicitly connect two of the three IDES16 primitive calibration inputs and could not achieve normal decryption all day!

But in the end we have the final required primitive for the Himbaechel-#gowin architecture working properly!
#sipeed #apicula #fpga

The massive Himbaechel-gowin backbone is already in decent condition and works on boards from #tangnano GW1N-1 already out of stock to the last one I have #tangprimer20k
It remains for me to implement a large piece of IO / IOLOGIC. Unfortunately it won't be photogenic - sort of like this TBUF check on the GW1NZ-1 Himbaechel-gowin. So I won't bother with the same blinking LEDs, but know that work is in full swing
#fpga #apicula #sipeed #gowin

But let's not forget the youngest models - #tangnano has its own troubles - instead of special IOs on the bottom edge of the chip, there are non-standard IOs on the side edges.
I implement the Himbaechel architecture on all the boards I have. Someday I'll save money for tangnano20k
#fpga #sipeed #apicula #gowin

Himbaechel P&R architecture for #gowin chips has learned how to handle the part of the IO needed to run a VGA display. The frequencies are generated using a PLL.

So, pll ran on tangnano9k with Himbaechel-gowin neatly changing the frequency when pressing the button :) That is, completely repeating the examples for legacy nextpnr-gowin. Now it is necessary to make changes in the clock router again so that PLL outputs go through the global network. And also make PLL for GW2A-18, there are 4 of them there

yay! I've been looking for a bug for a week and here it is finally - Himbaechel gowin compiles this attosoc thingy and it works!
It looks for prime numbers properly: 3, 7, 11, 13, 17, 19, 23, 29, 31

3 didn't fit in the movie.
