Tiny C Compiler in #WebAssembly supports <stdio.h> ... Thanks to the ROM FS Filesystem from Apache #NuttX RTOS

Here's how we boot #RISCV Milk-V Duo S over TFTP ... Thanks to U-Boot Bootloader 👍

#RustLang Apps run OK on #Ox64 BL808 #RISCV SBC ... With Apache #NuttX RTOS! 🎉

@Blort Thank you so much! :-)
#RISCV Sophgo SG2000 SoC: Reference Manual (T-Head C906 / Milk-V Duo S)
Try our demo of Tiny C Compiler in #WebAssembly ... Which will compile and run Apache #NuttX Apps!

By not having a Dual-Culturalist, like me, on the team.
When the twin towers in Kuala Lumpur was being built, I was friends with some guys on the project management team and some guys at Tyco (electrical subcontractor);
"We work hard. Easily 10 hours a day... but we can't keep up with the Japanese [one of the towers]...12 hours a day, six days a week, and let's not mention the Koreans, 14 hours a day, 7 days a week, and 1 day off per month."
There was a race to completion.
#RustLang Apps for #QEMU #RISCV ... We'll target riscv64gc (not riscv64i) on Apache #NuttX RTOS

An interesting clash of Western and Eastern work cultures.
But I wonder, how did this fall through the cracks?
Tiny C Compiler runs in #WebAssembly but it's missing C Header Files ... Let's add the ROM FS Filesystem from Apache #NuttX RTOS ... With a little help from #ZigLang Compiler
It's alive! Milk-V Duo S with #RISCV SG2000 ... USB UART Dongle must be CP2102, it doesn't like CH340G 😬

@Lup Yuen Lee 李立源 you know, I've been considering something like this with a Kindle 2nd generation which didn't come with WIFI but was one that used the 3G network. I've been thinking of ways to mate it with one of the very smallest #ESP32 on the market, to make that particular generation of Kindle Ereader, WIFI capable.
Because of USB Network hacks, the Kindle 2nd generation runs Linux on a MIPS processor and the front end is mostly Java code I think. Anyway, I'm going to plan carefully before I even attempt it but it would be a sweet little hack, I think.
