Hi.
I wrote a program which consists of 1 interrupt (by PWM) and UARTs.
However, I don't use Serial1 or other libraries for Arduino. I wrote my own UART library which uses polling mode instead of interrupt (polling inside pwm interrupt).
The codes works well with SOM-128. However, it doesn't work on 1G version. I have checked pwm interrupt and it still runs, however, no UART comes out of the board.

My hypothesis is that writing my own library does something with memery, and the address may not be the same for 1G version.
I tried to observe my UART library, and it seems that for TX1 & RX1, uartConfigBaseAddress is 3072 and uartBaseAddress is 1016.
