PROCESSOR-SDK-AM62P: UART (RS485) DTS configuration

YuYuan Wang

Part Number: PROCESSOR-SDK-AM62P
Other Parts Discussed in Thread: AM62P

Tool/software:

My project uses the AM62P with SDK version 10.00.07.04 (Kernel 6.6) and requires 5 UARTs, some of which need to be configured as RS485.

My question is:

In the EVM's DTS, main_uart0 has an additional interrupts-extended setting. Is this necessary?

if this setting is necessary, how should the other UARTs be configured? I also need to enable mcu_uart0, wkup_uart0, main_uart1, and main_uart6

Configure the UART port to RS485
My schematic as below

I'm not sure how to configure it for RS485. Could someone help me verify this?

&mcu_pmx0 {
	// UART3 - RS485
	wkup_uart0_pins_default: wkup-uart0-default-pins {
		pinctrl-single,pins = <
			AM62PX_MCU_IOPAD(0x0024, PIN_INPUT, 0) /* (D8) WKUP_UART0_RXD */
			AM62PX_MCU_IOPAD(0x0028, PIN_OUTPUT, 0) /* (D7) WKUP_UART0_TXD */
			AM62PX_MCU_IOPAD(0x0030, PIN_OUTPUT, 0) /* (C6) WKUP_UART0_RTSn */
		>;
	};
};

// wkup_uart0 | UART3 | /dev/ttyS1 | RS485
&wkup_uart0 {
	pinctrl-names = "default";
	pinctrl-0 = <&wkup_uart0_pins_default>;
	status = "okay";
	rs485-rts-active-high;
	rs485-rts-delay = <0 0>;
	linux,rs485-enabled-at-boot-time;
	bootph-all;
};

I looked at some examples, and it seems that the enable pin needs to be set as a GPIO, then passed in through rts-gpios

&mcu_pmx0 {
	// UART3 - RS485
	wkup_uart0_pins_default: wkup-uart0-default-pins {
		pinctrl-single,pins = <
			AM62PX_MCU_IOPAD(0x0024, PIN_INPUT, 0) /* (D8) WKUP_UART0_RXD */
			AM62PX_MCU_IOPAD(0x0028, PIN_OUTPUT, 0) /* (D7) WKUP_UART0_TXD */
			
		>;
	};
	// UART3 - RS485-Enable-pin
	UART3EN_pins_default: UART3EN_pins_default {
		pinctrl-single,pins = <
			AM62PX_MCU_IOPAD(0x0030, PIN_OUTPUT, 7) /* (C6) WKUP_UART0_RTSn.MCU_GPIO0_12 */
		>;
	};
};

// wkup_uart0 | UART3 | /dev/ttyS1 | RS485
&wkup_uart0 {
	pinctrl-names = "default";
	pinctrl-0 = <&wkup_uart0_pins_default &UART3EN_pins_default>;
	rs485-rts-active-high;
	rs485-rts-delay = <0 0>;
	rts-gpios = <&mcu_gpio0 12 GPIO_ACTIVE_HIGH>;
	linux,rs485-enabled-at-boot-time;
	status = "okay";
	bootph-all;
};

is this correct?

Hi YuYuan,

YuYuan Wang said:

This is for using UART0 to wake up the AM62Px device from Low Power mode. You don't need this if your project doesn't use any Low Power mode or don't use UART as the wakeup source.

YuYuan Wang said:

The kernel driver supports both native RTS or gpio based (rts-gpios DT setting) RTS pin for RS-485 direction control. So technically you can use either way.

However, the AM62Px UART controller supports RTS pin RS-485 mode, in which the controller manipulate the RTS pin for RS-485 direction control without software involvement. If you want to use this hardware feature, you would have to set the RTS pinmux to RTS mode, not GPIO mode, and don't set 'rts-gpios' in devicetree.

Hi Bin,

Thanks, but do you know why "wkup_uart0" failed in my system (TI's EVM SK-AM62P-LP)?

I tried this DTS in my kernel (I removed the other peripheral settings and kept only the UART settings that I need.)

Hi Bin,

This is a bit odd. The same modification doesn't cause any issues when applied to the full Yocto build.

My Yocto env was created by the following command

$ git clone https://git.ti.com/git/arago-project/oe-layersetup.git ${tmp_folder} && cd ${tmp_folder}
$ git checkout 8c2145fdb5c2d1196468350dcd6c54c72935459a
$ ./oe-layertool-setup.sh -f configs/processor-sdk/processor-sdk-scarthgap-chromium-10.00.07.04-config.txt

I updated the kernel from the "makefile SDK" using the following commands. Is there anything wrong with this process?

MYSD="/dev/sda"
rm -rf rootfs
make linux_clean
make linux
make linux_stage
mkdir rootfs && \
sudo mount ${MYSD}2 rootfs && \
sudo DESTDIR=rootfs make linux_install && sync && \
sudo umount rootfs && rm -r rootfs

Hi YuYuan,

The kernel boot log doesn't show the wkup_uart related messages.

dev@ula:tmp$ grep 'serial: ttyS' 20240907.log 
[    1.077635] 4a00000.serial: ttyS4 at MMIO 0x4a00000 (irq = 249, base_baud = 3000000) is a 8250

Then I checked the kernel devicetree which you posted on last Friday, it doesn't show wkup_uart0 is enabled.

Hi Bin,

Does this not indicate that wkup_uart0 is enabled? If not, could you guide me on how to enable it?

Thanks!

0 Bin Liu 11 months ago in reply to YuYuan Wang

TI__Guru**** 167581 points

Hi YuYuan,

Yes, it should be enabled based on this devicetree settings. I missed it earlier when searching for it.

What is the output of the following command on your board?

# zcat /proc/config.gz |grep UARTS

Hi YuYuan,

Thanks for providing the dtb file, it doesn't seem to have anything wrong either.

Now I am not sure what else could cause the wkup uart not enabled during kernel boot. I will have to test this on my SK-AM62P EVM tomorrow.

TI__Guru**** 167581 points

Hi YuYuan,

Okay here is the problem - your wkup uart device tree used rts-gpios, which points to a gpio pin in the mcu gpio module. However the mcu gpio module is disabled in device tree by default. This causes kernel failed to enable the wkup uart.

Please apply the following kernel device tree patch to enable the mcu gpio module.

Hi Bin,

I tried your solution, but it did not work.

If you look at my DTS, I had already commented out those lines before.

0 Bin Liu 11 months ago in reply to YuYuan Wang

TI__Guru**** 167581 points

Hi YuYuan,

For debugging, can you please try to remove the following line from the &wkup_uart0 node in the kernel device tree to see if kernel can initialize the wkup uart?

rts-gpios = <&mcu_gpio0 12 GPIO_ACTIVE_HIGH>;

0 YuYuan Wang 11 months ago in reply to Bin Liu

Hi Bin,

I removed the rts-gpio, but the result is still the same.

Hi YuYuan,

This is really strange. When I build the entire image using Yocto, everything works fine. However, this issue occurs when I use the legacy SDK(Makefile) to update only the kernel and U-Boot.

Please show the details (command & logs) about how exactly you did in using the SDK Makefile to update the kernel and U-Boot.
