Responses:
Part Number: TDA2 Tool/software: Linux 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: U-Boot SPL 2016.05-00009-gac1d50feef-dirty (Jun 14 2018 - 16:56:55) DRA752-GP ES1.1 no pinctrl for ddr_1_8v Card did not respond to voltage select! *** Warning - MMC init failed, using default environment Trying to boot from MMC1 reading dra7-ipu2-fw.lzop spl_load_file_fat: error reading file dra7-ipu2-fw.lzop, err - -1 spl: error reading image dra7-ipu2-fw.lzop, err - -1 Error loading remotecore IPU2!,Continuing with boot ... reading dra7-dsp1-fw.lzop spl_load_file_fat: error reading file dra7-dsp1-fw.lzop, err - -1 spl: error reading image dra7-dsp1-fw.lzop, err - -1 Error loading remotecore DSP1!,Continuing with boot ... reading dra7-dsp2-fw.lzop spl_load_file_fat: error reading file dra7-dsp2-fw.lzop, err - -1 spl: error reading image dra7-dsp2-fw.lzop, err - -1 Error loading remotecore DSP2!,Continuing with boot ... reading dra7-ipu1-fw.lzop spl_load_file_fat: error reading file dra7-ipu1-fw.lzop, err - -1 spl: error reading image dra7-ipu1-fw.lzop, err - -1 Error loading remotecore IPU1!,Continuing with boot ...

Hi Yuting, I have pinged mmc experts. Regards, Yordan

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. U-Boot SPL 2016.05-00009-gac1d50feef-dirty (Jun 14 2018 - 16:56:55) DRA752-GP ES1.1 Regards, Vishal

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"; Regards, 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. Regards, 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. Regards, 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). Regards, Yordan
