Hi, I started playing with Nano board (SPI flash version). I’m trying to put there u-boot via UART0 pins. I have a problem with finding them. I tried to connect to pins probably marked as UART’s RX/TX, but I cannot communicate through them. Silk screen marking are a little bit confusing, to I tried to find a pinout diagram.
I have found this one (lichee_nano_new.pdf): https://pan.baidu.com/s/1smzuGS9#list/path=%2Fsharelink3658413294-628283680456500%2FLichee%20Nano%2FSCH%20%26%20Lib&parentPath=%2Fsharelink3658413294-628283680456500
But now I’m even more confused. Maybe I’m reading it wrong, but for me looks like the UART0 is located on opposite side than marked on PCB.
Where I need to connect to access UART0 TX/RX pins?
And also - does someone have “nice&clean” Lichee Pi Nano pinout diagram?
