Thank you kind man.

Sorry, not planned. In the near future, an I2C(TWI) driver and examples of working with TS NS2009, RTC PCF8563, FM Radio RDA5807, HDMI IT66121 will be added.

Bare metal:
USB Device & Mass Storage Class
USB Host & Mass Storage Class
USB Host & USB-Ethernet adapter (RTL8152B & lwIP)

I used this board to check the power consumption of the processor. This board has two layers. I am currently using f1c_dbc board

F1C100S CoreMark @ 768MHz: 1729
But do not forget that in addition to processor performance, memory performance is also important.

Example of using USB-Ethernet adapter and lwIP-library.
Adapters based on the RTL8152B chip are supported. The driver from u-boot was taken as the base. This program runs on bare metal and depends on the lwIP TCP/IP stack. In this example, the available services are ping, iperf, and http server. At the same time, iperf demonstrated the use of a bandwidth of more than 90Mbits/sec.

Now I have too little time. Because of the war, I had to leave my city and now I settle down with my family in a new place. At the moment I have an MPEG1/2 decoder implementation. I'll try to put it out as soon as possible in my repository: https://github.com/minilogic/f1c_nonos

Register TCON->T0_IO_CTRL[0] allows you to set the polarity of the signals.

Can anyone share this file here?

Yes. See makefile:
run:    all
    $(FEL) -p spl $(BOOT).bin
    $(FEL) -p write 0x80000000 $(NAME).bin
    $(FEL) exec 0x80000000
flash:    all
    $(FEL) -p spiflash-write 0 $(BOOT).bin
    $(FEL) -p spiflash-write 32768 $(NAME).bin

Why?

This project is based on CEDRUS sources.
JPEG decoding is fast. YUV2RGB converting in the first sources is slow (~60mS), so in the mjpeg demo I did a table conversion (~24mS).

Thank you!
There are fights near my city.
We will win!
