T113-S4 1080P RGB_MIPI_LVDS_8080 LCD

Compile the Audio mixer of lvgl demo. The GT9xx touch screen runs normally and displays normally. The UI uses the hardware rotation function of G2D and does not burden the CPU.

The PCB has been manufactured and is ready for components to be soldered.

Completed the PCB design of the stamp hole core board.
Found a newly launched 32Gbits=4GBytes industrial temperature SD Nand, used it to load the Linux system, and integrated the RTL8211 1000M phy chip on the back of the PCB.

We 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.
