8-bit IO

The TS-SER4 supports 4 UARTs as RS-232, RS-485, or RS-422.

Refer to the TS-SER4 manual for hardware documentation.

The TS-SER4 implements 16550A based UARTs which require a kernel driver.

Under Linux this requires a device tree change. See the Kernel compile section for more details about getting set up the compile the kernel.

Open the device tree at arch/arm/boot/dts/imx6ul-ts7250v3.dts:

pc104bus: fpgaisa@50 {
	compatible = "technologic,pc104-bus";
	reg = <0x50 0x4>;
	ranges = <0 0 0x1000>;
	reset-gpio = <&gpio3 7 0>;
	#address-cells = <0x1>;
	#size-cells = <0x1>;

	status = "okay";

	/* For TS-SER1 set IRQ6+COM3 jumpers on: */
	ts16550@3e8 {
		compatible = "technologic,ts16550";

		reg = <0x3e8 8>;
		interrupt-parent = <&fpga_intc>;
