Ticket Name: How to burn the sd card file to emmc Tda2ex-17 (SDK V03.08)

Query Text:
Other Parts Discussed in Thread: TDA2, SYSBIOS Dear all, I'm just a beginner As shown in the title! Currently only use sd card to boot I’m not sure about the creation process and other settings like uenv-emmc.txt May I ask which document is talking about how to burn the emmc part? I don’t know the first thing to know and what to do at the beginning Although there are many related issues But is there a detailed document for reference? The part about burning into emmc! Can anyone give me some suggestions on the above issues ===================================================================== And how to enter terminal like => root@dra7xx-evm:~# Beacuse I put sd card into board and starting My log starts directly here ------------------------------------------------ TDA2Ex SBL Boot DPLL Configuration Completed Clock Domain Configuration Completed Module Enable Configuration Completed TI EVM PAD Config Completed DDR Config Completed App Image Download Begins SD Boot - file open completed successfully MPU CPU0 Image Load Completed IPU1 CPU0 Image Load Completed IPU1 CPU1 Image Load Completed IPU2 CPU0 and CPU1 Image Load Completed .....................etc -------------------------------------------------------------- I’m not sure how to get in root@dra7xx-evm:~# Which paragraph may I have missed The above are some of my questions. Please help me . VERY THANKS!!

Dear all, Please tell me if there is something unclear Thanks!

Dear all, By the way , when I was in Bulid The different settings are MAKECONFIG=tda2xx_evm_linux_all => MAKECONFIG=tda2ex_evm_bios_all

Dear all, Is it because we are a custom board? Because some related settings are not done and directly with your EV setting to run, so there is no way to run to => root@dra7xx-evm:~# Is it? What can I do about those related settings? Are there other documents or suggestions?

Dear all, 【Supplement】 And my VisionSDK_Linux_UserGuide.pdf did 4 .3 steps But the log does not show anything Next However I did VisionSDK_UserGuide_TDA2Ex.pdf
Some later steps gmake -s sbl and gmake -s appimage
Generate MLO and appimage to overwrite the original MLO (without apimage) Have Log ------------------------------------------------ TDA2Ex SBL Boot DPLL Configuration Completed Clock Domain Configuration Completed Module Enable Configuration Completed etc.... --------------------------------------------- But VisionSDK_Linux_UserGuide.pdf did 4 .3 steps Why is there no system log?? Is there a problem? Because we are a custom board, what should I pay attention to and set?  

If you set MAKECONFIG=tda2ex_evm_bios_all and build "gmake -s sbl", the MLO is for the baremetal bootloader for TI-RTOS (SYSBIOS). For Linux, you should set MAKECONFIG=tda2xx_evm_linux_all. However, sbl build is only for RTOS, not Linux. To build the bootloader (spl/u-boot) for Linux, you have to build from linux u-boot on Ubuntu PC. VisionSDK_Linux_UserGuide.pdf has all the steps documented. You have to follow the steps from the beginning to set up Linux build environment. Regards, Stanley

Dear Stanley, Step1 !!! I did the steps above in the document (VisionSDK_Linux_UserGuide.pdf) And my MAKECONFIG is tda2ex_evm_linux_all I have done step 4.2,Then burn it into the SD card When I put it in our coustom board, """ there is no log """ =================================================================== Step2 !!! Then I did another thing I will overwrite the MLO and put in appimage built by the window => tda2ex_evm_bios_all  (These two files are completed under the window ) But there is a log out Like this ------------------------------------------------ TDA2Ex SBL Boot DPLL Configuration Completed Clock Domain Configuration Completed Module Enable Configuration Completed etc.... --------------------------------------------- ============================================================================== The key problem is!! when I was in step 1!!! Why did I complete 4.2 and put the sd card into our costom board and there is no log display???? Why did I do the second experiment but it works like this(Step2 !!!) ? Is there something wrong?? I have followed VisionSDK_Linux_UserGuide.pdf, but the 4.3 step is still unsuccessful Thanks!!!!!

One possibility is that Linux u-boot SPL (MLO) got stuck since you were booting the MLO for EVM on the custom board. Do you have JTAG to connect the device and check what is going on with debugger? You can use Lauterbach JTAG with Trace32 or XDS560v2 JTAG with CCS to debug. Regards, Stanley

Dear, Q1. So it may be the relationship of the custom board? Because it doesn’t match with MLO?? =============================================================== Q2.in addition ,If Q1 is right I want to ask, is it because some need to be set according to our board? Is there any direction to tell me what needs to be modified? ============================================================= I will learn about the debug method and try it out Please tell me these two answers Thanks!!

Q1: Yes Q2: You have to identify what is different between your board and EVM. For example, if DDR is different, you have to update EMIF configuration or the access to DDR may not work. There are other things like Pin mux, PMIC, and etic. Regards, Stanley

Thank you!!

Dear Stanley, I want to check some places Please help me with these problems ================================================================ Q1 : Would like to ask how to determine if MLO has been executed? Q2: Where is the TDA uart port set? I also suspect that the port may be wrong, so I want to check Q3: Where is the MLO log printed? And where is the MLO source code ?? And where it started to run?? Q4: Where is the ROM code??, I want to know how the process of booting to MLO to display log is Q5: Is there any clear information about the boot process (part of the program)? ================================================================= If there is something wrong with the question I asked, please let me know Thank you !

Dear Stanley, But the DDR of my RTOS is the same as LINUX DDR RTOS can see log but LINUX does not Just changed MLO, any other suggestions? Thanks!

Dear Stanley, Can you help me this issue? Thanks!

Dear Stanley, But the DDR of my RTOS is the same as LINUX DDR RTOS can see log but LINUX does not Just changed MLO, have any other suggestions? and I I opened another thread e2e.ti.com/.../3799935 Thanks!

Could you download the pre-built binaries from the below link? http://software-dl.ti.com/infotainment/esd/jacinto6/processor-sdk-linux-automotive/latest/index_FDS.html boot-dra7xx-evm.tar.gz will include the MLO and u-boot. Can you try this on your board first?
