It's a bit easier to just use something like a W5500 chip directly via SPI (Scott already has code working for this).
With FlexiHAL we have a small add-on module in the works so that people aren't reliant on a Pi even though they are getting easier to find - we have not yet found another SBC that has adequate GPU driver support for Probe Basic.
Currently working on DMA transfers (even just using IRQ is a reasonable improvement), again just following on from the work that Scotta has already done.
The Milk-V Duo is a small RISC-V embedded platform capable of running Linux and RTOS. The low-cost device features up to 26x GPIOs, optional 10/100Mbps Ethernet support and integrated with a H.264/H.265 video compression encoder and ISP.
The product page indicates that his Milk-V Duo is based on the SOPHGO CVITEK CV1800B (C906 @1Ghz + C906 @700MHz) System-on-Chip with up to 64MB DDR2 memory. The company indicates that the Duo integrates CVITEK TPU for smart detection and supports H.264/H.265 video encoding, up to 2880×1620 @20fps.
They have something going on with with remora comp and an stm32f103 bluepill board, but i didnt see any firmware posted. I sent them an email a few weeks ago but no reply
Greetings dev,
I have NucleoF446ZE board and tried to flash relevant firmware along with config.txt.
I have also connected SPI pins as suggested in docs.
Starting linuxcnc, axis screen lives but doesn't comes out of e-stop.
When I run in terminal I got error
Bad SPI payload =0
Hey virencq, can you show me which firmware/docs you were using?
I have a nucleo specific set of documents and firmware, but its specific to the Nucleo64 STM32F446RE. I havent tested it with the 446ZE, I have to check some pin compatibility between the RE and ZE. I will test with my special nucleo firmware , but I made some changes regarding (lack of) pins for the 446re, so it may need some minor changes. The firmware might work with ZE but I doubt it compile properly
In the meantime, if you want to fool around with it, here are the nucleo repos ive been working on
