I'm trying to use the UART1 of the HPS and route to an external connector, the peripheral is enabled in Qsys, its outputs exported and connected to external pins in the FPGA, the device tree updated.
In Linux:root@DE10_NANO:~# dmesg | grep tty
ffc02000.serial: ttyS0 at MMIO 0xffc02000 (irq = 24, base_baud = 6250000) is a 16550A
console enabled
ffc03000.serial: ttyS1 at MMIO 0xffc03000 (irq = 25, base_baud = 6250000) is a 16550A
If I send data to the ttyS0, I can see the information on a serial terminal. But If I send data to ttyS1, nothing is received in the connector pins connected to the FPGA. Does someone has had success using the ttyS1 on the DE10-Nano? Thank you. [Edit: Solved recompiling the preloader]
