I’m trying to use a 3.5inch HDMI LCD, 480x320, IPS touchscreen on a jetson xavier nx.
I saw this post and followed it, and the spi1 was modified for Jetson Xavier NX (maybe I was wrong)
compatible = “ti,ads7846”;
reg = <0x1>; // CS1 of SPI
spi-max-frequency = <0x7a120>;
nvidia,rx-clk-tap-delay = <0x7>;
interrupt-parent = <0x13>; // phandle of "gpio@2200000"
interrupts = <0x42 0x1>;
pendown-gpio = <0x13 0x42 0x0>;
vcc-supply = <0x27>; // phandle of "regulator@101"
//ti,swap-xy = <0x1>; // uncomment to swap axes
ti,x-min = [00 00];
ti,x-max = [1f 40];
ti,y-min = [00 00];
ti,y-max = [12 c0];
ti,x-plate-ohms = [00 28];
ti,pressure-max = [00 ff];
nvidia,cs-setup-clk-count = <0x1e>;
nvidia,cs-hold-clk-count = <0x1e>;
nvidia,rx-clk-tap-delay = <0x1f>;
nvidia,tx-clk-tap-delay = <0x0>;
I rebooted and checked the error message from dmesg.
What is this error message?
What am I doing wrong?
