Linux/TDA2: change log output uart 1 to uart3

Widic Jane

Part Number: TDA2
Other Parts Discussed in Thread: DRA742, PCF8575, PMP, DRA752

Tool/software: Linux

in u-boot modified board/ti/dra7xx/mux_data.h and u-boot/arch/arm/dts/dra7-evm-common.dtsi
1 in file board/ti/dra7xx/mux_data.h
change /*{UART2_CTSN, (M3 | PIN_INPUT_PULLUP)},    /*uart2_ctsn.mmc4_dat2*/
    /*{UART2_RTSN, (M3 | PIN_INPUT_PULLUP)},    /*uart2_rtsn.mmc4_dat3*/
     to
{UART2_CTSN, (M2 | PIN_INPUT_PULLUP| SLEWCONTROL)
        {UART2_RTSN, (M1 | PIN_INPUT_PULLUP| SLEWCONTROL)

2 u-boot/arch/arm/dts/dra7-evm-common.dtsi:14:
change stdout-path = &uart1;
to
stdout-path = &uart3;

uart3 already has log output but kernel stopped

In addtition£¬I modified /kernel/omap/arch/arm/boot/dts dra72-evm-common.dtsi
stdout-path = &uart1;
{
    aliases {
        display0 = &hdmi0;
        sound0 = &sound0;
        sound1 = &hdmi;
    };

    chosen {
        stdout-path = &uart3;
    };
Block some code in dra72-evm.dts about MMC4's part.

what is the reason of the question?

I found that board-support/linux/arch/arm/configs/ti_sdk_dra7x_release_defconfig changed CONFIG_DEBUG_OMAP2UART1=y 1modfied to 3.
make linux£¬CONFIG_DEBUG_OMAP2UART3=y can auto reback CONFIG_DEBUG_OMAP2UART1=y

How to fixed it?

Linux ： how to change kernel log output port?

how to change the .config uart1 to uart3 ?

Hi Widic,

I merged your threads into one.

Can you clarify what exactly is your problem - if I understand correctly you have successfully enabled uart3 logs for both u-boot and kernel, but the kernel stops for some other reason (mmc)? Can you also attach full boot log?

Regards,
Yordan

Hi,Yordan,

We has the same problem for TDA2x, and I can offer you the full boot log as follows:

Hi Yuting,

UART is not the issue as you are able to see both u-boot and kernel logs on console.

What board is this? your own board or TI EVM?
Which SDK and release are you using?

According to the u-boot log this is a different part number.
dra72-evm-common.dtsi file is not the right one, you have to look at dra7-evm.dts and dra7-evm-common.dtsi file for this board.

Hi Vishal,
1.This board is TI TDA2X EVM ,and CPU is DRA752.
2.We are using PROCESSOR_SDK_VISION_03_03_00_00 at linux.
In order to change log output uart 1 to uart3, we changed the u-boot and kernel which caused this problem. And log output is normal using uart1, but uart3 has caugth the problem above. Then I will tell you what I have done.
First, we modified the u-boot：menuconfig：uart3 used for console , and modified files of board/ti/dra7xx/mux_data.h and u-boot/arch/arm/dts/dra7-evm-common.dtsi，
1、board/ti/dra7xx/mux_data.h
modified
{UART2_CTSN, (M3 | PIN_INPUT_PULLUP)}, /*uart2_ctsn.mmc4_dat2*/
{UART2_RTSN, (M3 | PIN_INPUT_PULLUP)}, /*uart2_rtsn.mmc4_dat3*/
as
{UART2_CTSN, (M2 | PIN_INPUT_PULLUP| SLEWCONTROL)
{UART2_RTSN, (M1 | PIN_INPUT_PULLUP| SLEWCONTROL)

2、u-boot/arch/arm/dts/dra7-evm-common.dtsi:
modified
stdout-path = &uart1;
as
stdout-path = &uart3;

Then we modified the kernel： menuconfig：uart3 used for console ，and modified the files of
/arch/arm/configs/ti_sdk_dra7x_release_defconfig， dra7-evm-common.dtsi and dra7-evm.dts.
1、ti_sdk_dra7x_release_defconfig
modified CONFIG_DEBUG_OMAP2UART1=y as CONFIG_DEBUG_OMAP2UART3=y
2、dra7-evm-common.dtsi
modified
stdout-path = &uart1;
as
stdout-path = &uart3;
3、dra7-evm.dts
modified
0x3f8 (PIN_INPUT_PULLUP | MANUAL_MODE | MUX_MODE3) /*uart2_ctsn.mmc4_dat2 */
0x3fC (PIN_INPUT_PULLUP | MANUAL_MODE | MUX_MODE3) /* uart2_rtsn.mmc4_dat3 */
as
0x3f8 (PIN_INPUT_PULLUP | MANUAL_MODE | MUX_MODE2)
0x3fc (PIN_INPUT_PULLUP | MANUAL_MODE | MUX_MODE1)

Finally，we modified the uenv.txt
args_mmc=part uuid mmc 0:2 uuid; setenv bootargs "console=ttyO0,115200n8 elevator=noop root=PARTUUID=${uuid} rw rootwait earlyprintk fixrtc omapdrm.num_crtc=2 consoleblank=0 cma=128M@0xB0000000 rootfstype=ext4 snd.slots_reserved=1,1"

modified
console=ttyO0
as
console=ttyS2

After that，the problem is showing out.

Hi,

If this is a TI EVM why are you changing the console from UART1 to UART3?

Also, since you are changing pinmux of mmc4 to be used as uart3 pins, try disabling mmc4 from dra7-evm.dts
Change status of mmc4 to disabled and test.

&mmc4 {
status = "okay";

&mmc4 {
status = "disabled";

Vishal

Hi,Vishal,
we want to use UART1 as another function,so we have done some changes for the TI EVM.

And I have tried disabling mmc4 from dra7-evm.dts, also, Change status of mmc4 to disabled .But the problem is the same.

Yuting

Hi Yuting,

-1-

Do the below changes to Kernel and share the logs,
-- Enable CONFIG_MMC_DEBUG option in Kernel config
-- Append "loglevel=9" to args_mmc of uenv.txt

-2-
Check the H/W modifications and make sure you have not done any unwanted changes to board other than UART.

Vishal

Hi Yuting,

We haven't heard back from you, I'm assuming you were able to resolve your issue.
If not, just post a reply below (or create a new thread if the thread has locked due to time-out).
