ElecLabWe upgraded the hardware to use T113-S4, which has built-in 256M DDR3 memory and added a 1GHz 64bit C906 RISC-V processor, which can run freertos/Nuttx.
We also upgraded the wifi module to the WIFI6 version of AIC8800D80, which greatly improved the wireless speed.
When the wifi6 signal quality is high, the speed of iperf3 -c is around 270M and the speed of iperf3 -s is around 300M.
Of course, a 512MB SD Nand storage chip is also installed for it, so that the system and programs can be solidified inside.

HI, our code is not yet organized, and we use the uboot of Tina5.0. We have used buildroot2024 and linux6.12 lts on T113-S3, but have not yet fully tested.

Hello I've already built a T113-S4 board, almost all works fine, but audio decoder doesn't work. I think that mainline u-boot doesn't configure well the clocks. Which u-boot are you using?
