VIM3 Pro
ubuntu20.04 kernel 4.9
To control Robots, I need IMU sensor which communicates via UART.
Unfortunately, The UART3 in 40P-GPIO (Pin15, Pin16) is already used by SPI communications.
the debug serial port seems the only choice I have.
So,How to turn the debugging serial port into an ordinary serial port?
By the way, I connect IMU sensor RX and TX to Linux-Tx and Linux-RX. When powering is on. The IMU sensor immediately sends data to VIM3, But the VIM3 can’t correctly startup. It seems stuck on the autoboot.
I emulate the IMU data send to vim3. The output is like below:
[KM]Error:f[keymanage_dts_parse]L307:not a fdt at 0x0000000001000000
gpio: pin GPIOAO_7 (gpio 7) value is 1

How could I change something to make the VIM3 boot correctly?
Please help me! Thanks a lot!
