串口收发问题

我使用 Jetson Orin Nano模组,定制的底板,串口不能正常使用
UART0和UART1是对应的/dev/ttyTHS1和/dev/ttyTHS2吗?
我往/dev/ttyTHS1接口发数据时,用示波器测量UART0_TXD引脚没有电平变化
是不是要使用串口还需要修改什么配置?

Hi qiaowei,

What’s your Jetpack version in use?

You can refer to Jetson/L4T/peripheral/ - eLinux.org for the mapping.

Please share dmesg for further check.

我使用 Loopback test ,不能正常收发,是需要外部TX和RX也接线吗?

下面是dmesg

我把这4个引脚:UART0_RTS,UART0_CTS,UART1_RTS,UART1_CTS 在设备树中改成普通IO了,有影响吗?

It seems you are using Jetpack6.0GA(R36.3).

[    3.624163] 3100000.serial: ttyTHS1 at MMIO 0x3100000 (irq = 112, base_baud = 0) is a TEGRA_UART

It is UART1 from 40-pin expansion header.

Yes, you need to short TX/RX externally for loopback test.
(i.e. PIN8(UART1_TX) and PIN10(UART1_RX) on 40-pin expansion header)

Do you mean the pinmux spreadsheet? If so, you should configure them as UART instead of GPIO.
You can refer to the following:

是的,我是用pinmux spreadsheet配置的,我们的定制载板已经把这4个引脚UART0_RTS,UART0_CTS,UART1_RTS,UART1_CTS做为其他GPIO使用了,串口只使用UART0_TXD,UART0_TXD,UART1_TXD,UART1_RXD这4个引脚可以吗?RTS和CTS是硬件流控功能,我不需要使用硬件流控应该怎么配置?

Okay, 如果你不需要使用RTS/CTS,那應該維持預設的設定就可以了


記得使用串口應用開啟UART時要關閉HW flow control

請問你把TX/RX從外部short後,UART loopback test可以成功嗎?

请问如何关闭HW flow control?

TX/RX从外部短接后还是不行,不确定是不是HW flow control没有关闭的原因

是通过stty命令就可以关闭吗?我是这样操作的:
image
下面是pinmux的配置

這根據你使用的Serial application

你現在是short 40-pins expansion header 上的PIN8和PIN10嗎?
請測試以下command:

$ sudo su
# stty -F /dev/ttyTHS1 115200 raw -echo
# cat /dev/ttyTHS1 &
# echo "Hello World" > /dev/ttyTHS1

我在DevKit上面测试UART1通了,UART1对应的设备是/dev/ttyTHS1,那UART0是/dev/ttyTHS2吗?因为没有/dev/ttyTHS0这个节点
我的定制载板还需要使用UART0,我把UART0的RX和TX短接,然后使用这个命令测试不通
image

不是。

UART0對應的是uartb@3110000,它在M.2 Key E
從你的log看起來目前device tree裡這個node還沒開啟

我的载板上UART0没有用于M.2 Key E,请问怎么开启UART0,我在设备树文件中没有找到uartb@3110000
是这个吗?我看到已经是开启了

我指的是在devkit上面從M.2 Key E接出來,你要根據自己的載板去找從module出來的訊號接到哪

你圖中的是serial@3100000, 不是serial@3110000

我在设备树中添加了uartb:


然后也启用了:

但是我查看状态还是禁用的:
image

Could you share the steps how you modify device tree?
Do you recompile the kernel image and dtb and reflash the board to apply the change?

我找到原因了,是在tegra234-soc-overlay.dtsi文件中覆盖了我的修改

Cool, can the loopback test working with UART0 on your board?

环回测试成功了,UART0对应的设备是/dev/ttyS0
感谢支持

這決定於你compatible那邊怎麼設定的,8250是另個serial driver

现在虽然环回测试成功了,但是时钟不对,19200波特率时,每个bit长度应为为52us;UART1就是这样的。
而UART0在19200波特率时,每个bit长度实测为0.5us。
我看到Linux_for_Tegra\source\hardware\nvidia\t23x\nv-public\nv-soc\tegra234-soc-overlay.dtsi里面是这样定义的,请问在怎么改UART0的时钟?

serial@3110000 {
			compatible = "nvidia,tegra234-uart", "nvidia,tegra20-uart";
			reg = <0x0 0x03110000 0x0 0x10000>;
			interrupts = <GIC_SPI TEGRA234_IRQ_UARTB IRQ_TYPE_LEVEL_HIGH>;
			clocks = <&bpmp TEGRA234_CLK_UARTB>;
			resets = <&bpmp TEGRA234_RESET_UARTB>;
			status = "disabled";
