OMAP-L138: Debug UART configuration

sharmila d

Part Number: OMAP-L138

Hi,

I am using a custom board with OMAP-L138 processor. I am using the latest processor sdk. I have few queries regarding UART configuration. We are using UART2 pins for communication.

The dts file configuration is as below

chosen {
stdout-path = "serial2:115200n8";
};

My bootargument is as below

setenv bootargs 'console=ttyS2,115200n8 ${mtdparts} root=ubi0:rootfs rw ubi.mtd=filesystem,2048 rootfstype=ubifs rootwait=1 loglevel=7 noinitrd mem=128M'

--->With this I am getting garbage message in the console (teraterm-115200 baud).

So I changed my bootarg to use ttyS1.

setenv bootargs 'console=ttyS1,115200n8 ${mtdparts} root=ubi0:rootfs rw ubi.mtd=filesystem,2048 rootfstype=ubifs rootwait=1 loglevel=7 noinitrd mem=128M'

--->with this no prints are displaying after

Starting kernel ...

Uncompressing Linux... done, booting the kernel.

So I changed my bootargs to use earlyconsole and ttyS1

setenv bootargs 'console=ttyS1,115200n8 ${mtdparts} root=ubi0:rootfs rw ubi.mtd=filesystem,2048 rootfstype=ubifs rootwait=1 loglevel=7 noinitrd mem=128M earlycon'

Booting continued and I am getting debug prints.

So I am bit confused here. Which one is the proper port?

Please provide your input ASAP.

Thank you,

With Best Regards,

Sharmila D

Hi Sharmila,

Are you using the Processor SDK v6.03, which has kernel v4.19?

When you switched the console from ttyS2 to ttyS1, you only modified the bootargs, nothing else?

Can you please provide the kernel boot log while using ttyS1 as the console port?

Hi Bin Liu,

Thank you for the reply.

Yes I am using processor SDK v6.03 and which has kernel 4.19.94.

When switching console from ttyS2 to ttyS1 I have modified only bootargs nothing else.

Please find the requested boot log attached FYR.

Why ttyS2 is giving garbage value when booting?

Thank you,

With Best Regards,

Sharmila

Hi Sharmila,

Which UART port(s) is routed out on your board, UART1 or UART2?

Does your board DTS have serial aliases as this on the da850-evm.dts?

 22         aliases {                                                               
 23                 serial0 = &serial0;                                             
 24                 serial1 = &serial1;                                             
 25                 serial2 = &serial2;

Hi Liu,

Connection is over UART2.

Yes my board DTS have serial aliases as below

arch/arm/boot/dts/da850-lcdk.dts

aliases {
serial2 = &serial2;
ethernet0 = &eth0;
};

chosen {
stdout-path = "serial2:115200n8";
};

arch/arm/boot/dts/da850.dtsi

serial2: serial@10d000 {
compatible = "ti,da830-uart", "ns16550a";
reg = <0x10d000 0x100>;
reg-io-width = <4>;
reg-shift = <2>;
interrupts = <61>;
clocks = <&psc1 13>;
power-domains = <&psc1 13>;

};

Thank you,

Hi Sharmila,

This is strange. I am wondering if this has anything to do with systemd, if you noticed in the end of the kernel boot log you attached, systemd start getty onttyS1. But earlier in the kernel log it shows ttyS2 is probed.

1d0d000.serial: ttyS2 at MMIO 0x1d0d000 (irq = 61, base_baud = 11250000) is a TI DA8xx/66AK2x

Does you board have the Ethernet port? If so can you switch bootargs setting back to ttyS2, then telnet to the board to get the kernel boot log?

0 Bin Liu over 4 years ago in reply to Bin Liu

TI__Guru**** 168631 points

BTY, when the console generates garbage with ttyS2, is it all garbage or only partially after certain point during kernel boots? Can you please take a pic of the garbage console?

0 sharmila d over 4 years ago in reply to Bin Liu

Hi,

Yes I am not getting the login prompt when ttyS1 is set in bootargs, getty service is restarting . If I change the getty service to use ttyS2 then garbage is coming after the service starts. Attached a log FYR.

I tried flashing prebuilt kernel image. Same behavior I observed , garbage when using ttyS2.

Yes my board is having Ethernet port, but not configured yet. Can you please provide some document for telnet procedure.

Thank you,

Best regards,

Sharmila D

If you use the rootfs from the Processor SDK release, telnetd is already included.

- add 'ip=dhcp' in the U-Boot bootargs, so that the board get an ip address automatically from the dhcp server after linux booted

- boot with console as ttyS1 and note down the ip address (or from the dhcp server log), it normally doesn't change when switching to console = ttyS2

- boot with console as ttyS2, then run command 'telnet <board-ip-address>' on your PC, you should be able to login from there

Hi,

The above mentioned procedure requires login prompt?

How to check whether ethernet is up and IP is assigned to the board?

Thank you,

WBR,

Sharmila

Yes, you need to login to the board to run any command on it.

You can use either ifconfig or ip command on the board.
