TDA2PXEVM: About early boot based on TI visionSDK 03 05

Part Number: TDA2PXEVM

Hi Shravan,

It still  crashes.It may be caused by the memory we changed.Our maximum memory is 512M, so,we modified necessary memory address and size according to our memory configuration.Could you help to have a look? Please find the failed boot log in attachment.

Thanks a lot

Terence

  • Hi Terence,

    Can you please provide the DTB being used. Also which all cores are you trying to bootstrap from u-boot? 

    Are you accessing UART from the remote-cores? I notice a failure in UART from the logs provided.



    Regards

    Shravan

  • Hi Shravan,

    1.we want to boot the cores of "dsp1,dsp2,ipu1,ipu2" from u-boot, and then the ipu is used to bootstrap  eve1. But I can't find the EVE binary in  targetfs. 

    2.Yes,  I also notice a failure in UART, does it will  affect startup?  I deleted the ipu1 binary in boot partition, it could startup normal, there is still have a failure in UART. Please find the log  in attachment.

    3.Below is the dts file.

    Thanks a lot for your help

    Terence

  • Hi Terence,

    I notice you've modified the cma regions for IPU and DSP. You need to make this modification in Vision-SDK and in u-boot.

    In Vision-SDK please modify apps/build/tda2px/mem_segment_definition_linux.xs and in u-boot you need to modify board/ti/dra7xx/lateattach.c the macros DRA7_RPROC_CMA_BASE for each core.

    Please perform a clean build after making all these changes.


    Regards
    Shravan

  • Hi Shravan,

    1. Yes,we changed it, but I'm confirmed that we have modified the same memory regions in Vision-SDK(apps/build/tda2px/mem_segment_definition_linux.xs)and in u-boot(board/ti/dra7xx/lateattach.c ) before.  Now, We try it again, system crash  remains.Please find the early_boot.log in attachment.

    2. In boot partition of my SD card,there are seven binaries include uImage, single-stage-boot.dtb, MLO, dra7-ipu2-fw.lzop, dra7-ipu1-fw.lzop, dra7-dsp2-fw.lzop,  dra7-dsp1-fw.lzop.

    3.The other problem, I delete the dra7-ipu1-fw.lzop in my boot partition of sd card, it does’t crash,  but it may be failure, because I see the log said “SYSTEM: Attaching to [IPU1-0]”, when running the app.out to test. Please find the early_boot_no_ipu1_in_boot_partition.log in attachment.

    Thanks a lot for your support

    Terence

  • Hi Terence,

    Can you add the below line to your DTB and let us know if it works.

    &ipu1 {
    timers = <&timer9>, <&timer11>;
    };

    Regards
    Shravan
  • Hi Shravan,

    Bad news, it doesn't work. Please find the early_boot_12_17_2018.log in attachment. I'm not sure that if the value of IPU1_LOAD_ADDR changed  in "u-boot\include\configs\ti_omap5_common.h" will lead to the system crash. I changed it from 0xb0000000 to 0x86000000, Because  the size of DDR is only 512M in the borad.

    Thanks a lot for your support

    Terence

  • Hi Terence,

    If you have only 512MB then you need to modify your load address to be less than 0xA0000000. An address you can use is 0x90000000. Don't use 0x84000000 as first 96MB is reserved for kernel.

    As a debug step, before you load kernel please make sure all the remote-core firmware is loaded by halting in SPL/MLO. You can do this by attaching a debugger and connecting all cores through CCS. Once this is confirmed please load kernel.

    Regards
    Shravan
  • Hi Shravan,
    1.According to VisionSDK_UserGuide_MemoryMap, it said "DDR3_LINUX_MEM_OFFSET = 64*MB", so we use first 64M for kernel. We use this memory map more than one year, it is normal. We modify the load address to 0x86000000 now just for debugging early boot.
    2.For early boot/late attach, I think that the most important problem is IPU1 loading failure. Because, if no ipu1 in the boot partition, it's normal now. For visionSDK 03 05 from TI, Do you sure that it's support to load ipu1 itself? We need IPU1 in early boot, so,we really need your help.

    Thanks a lot for your support

  • Hi Terence,

    1. For TDA2PX, we reserve 96MB for Linux kernel. This is because, we enable LPAE for TDA2PX since we have 4GB DDR on our EVMS. So we reserve 96MB for kernel data-structures and page-tables. Please refer to apps/build/tda2px/mem_segment_definition_linux.xs for this change.
    2. Yes, we do support Early-boot of IPU-1 in Vision-SDK. This has been tested as well. As indicated in previous posts, please halt at MLO without loading SPL and check if the IPU-1 firmware has been successfully loaded (you should be able to connect IPU-1 using JTAG and CCS).

    Regards
    Shravan
  • Hi Shravan,
    I 'm sorry. I don't understand that how to halt at MLO without loading SPL, and how to check if the IPU-1 firmware has been successfully loaded? Is there any document for reference?

    Thanks a lot for your support.
    Terence
  • Hi Terence,

    Please add the below change to halt at SPL/MLO.

  • Hi Shravan,
    Refer to CCS_Debug_Trace.pdf,I'm now installing Code Composer Studio v5.5, but there is a issue when I run ccs_setup_5.5.0.xxxxx.bin.

    Thanks a lot for your support

  • Hi Shravan,
    For early boot/late attach, I don't understand the relationship between the address of DRA7_RPROC_CMA_BASE_IPU1 in "u-boot/u-boot/board/ti/dra7xx/lateattach.c" and IPU1_LOAD_ADDR in "/u-boot/u-boot/include/configs/ti_omap5_common.h". Do we need to set them the same?

    Thanks a lot
    Terence
  • Hi Terence,

    The IPU1_LOAD_ADDR is the address to which the compressed lzop firmware is loaded to DDR (from the boot media). From here the firmware is uncompressed to DRA7_RPROC_CMA_BASE_IPU1.


    Regarding the CCS issue, please refer the documents in Vision-SDK. There are also plenty of other E2E threads you may find helpful. If the issue still persists please raise another E2E ticket, an expert will be able to help you .


    Regards

    Shravan

  • Hi Shravan,
    For early boot/late attach, the ipu1 may be load failure, the log said " failed to get resource section header".Below is the log, Could you help to have a look?

  • Hi Terence,

    Are you building IPU-1 FW along with Vision-SDK Linux? The error couldn't find resource header implies, you've not built Vision-SDK with IPU1_0=yes. Where are you building the IPU-1 firwmare?
    If built with Vision-SDK Linux configuration (tda2px_evm_linux_all), then the resource headers are automatically added to the firmware. The absence of resource header indicates that the firmware wasn't built as part of Vision-SDK and/or for a Linux configuration.
    The resource header is necessary to setup the MMU for IPU, which is necessary for Linux builds.

    Regards
    Shravan
  • Hi Shravan,
    Yes, We are building IPU-1 FW along with Vision-SDK Linux. Now, it could startup. According to your suggest,I changed the code to halt at SPL/MLO.Below is the log, it seems IPU1 is loaded successfully. But, when it jumps to kernel, it still scrash.For the log, why are the core entry point of ipu1 and ipu2 the same?

    Thanks a lot
    Terence

    I had found the cause of kernel panic. Due to the additional serial port settings in our application code. Now, after early boot, and late attach is normal.

    Thanks a lot
