    Hi,

    We have refered below mentioned ti-community link to flash using DFU, seems like it is flashing and observed in bootprints when booting from emmc
    URL : e2e.ti.com/.../faq-tda4vm-j721e-j7200-enabling-dfu-boot-on-8-0-linux-sdk
    URL : software-dl.ti.com/.../UG-DFU.html

    We are using SDK09.02

    Please check on the above request

    Regards,

    Hi Kaushal 

    Please go through the appnote to understand the flashing technique on TDA4  devices.

    TDA4 Flashing Techniques (ti.com)

    Let us know if you still have further question on this.

    HI Kaushal 

    DFU and UMS are two different things.

    Are you able to flash the emmc using DFU ?

    Hi Diwakar,

    We are able to flash using DFU Tool, but only tiboot3.bin and tispl.bin binaries are flashing but while trying to send u-boot.img we are facing below error

    ####MMC: block number 0x2110 exceeds max(0x2000)

    Also in flashing documentation it is mentioned to flash tiboot3.bin and sysfw.itb bins separately, but as per i understood sysfw.itb is embedded in tiboot3.bin, so is there any updates need to do while flashing this (like mmc write command block count)

    UMS is also a feature important to us to validate usb peripheral mode in uboot.

    Kindly do the needful

    Regards,
    Kaushal

    Are you testing it on EVM or on the custom board ? We have validated the steps so far we haven't came across any issue with the DFU.

    Help share the full  logs as well.

    The documentation was created a while ago based on TDA4VM device which follow legacy boot flow you are using DRA821 which uses combined boot flow no need to send sysfw.itb . TIFS will get packaged with the tiboot3.bin only.

    HI Kaushal 

    What is the size of the UBOOT image you are using ?

    Base on that you need to calculate the Block numbers and modify it in the k3_dfu.h

    Dear Diwakar,


    image size are mentioned below
    tiboot3.bin - 530666 bytes
    tispl.bin - 1018479 bytes
    u-boot.img - 1187547 bytes

    We tried to convert u-boot.img size to block (updated in dfu args) and write to emmc, still we are facing same issue

    HI Kaushal 

    What is the block numbers you kept and what was the error have you tried printing the dfu_alt_info_emmc in UBOOT 

    Regards
    Diwakar

    Intellectual 470 points

    Hi Diwakar,

    we have kept block size as 0x910
    In the DFU settings the uboot.img try to write from 0x1800 and block count of 0x910 which will exceeds (0x2000), but we are not sure how this limit(0x2000) is set..?

    it seems we are not able/allowed to change the starting address of the images in emmc (ex: tiboot3.bin - 0, tispl.bin - 0x800, uboot.img - 0x1800) because sourcecode will expect the binaries from this address.

    Regards,

    Hi Kaushal 

    Please go through my earlier response on how to set the number of blocks

    https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1393440/dra821u-emmc-flashing-using-dfu/5341516#5341516

    After making above changes you need to build the UBOOT using command "make u-boot".

    Dear Diwakar,

    We are able to flash and boot in emmc using DFU, but when kernel is loading we observed gpt partition table is created during flashing procedure
    gpt write mmc 0 ${partitions}
    and we flashed rootfs using dfu as mentioned below
    sudo dfu-util -a rootfs -D rootfs.wic

    we suspect gpt partition is causing the issue, while loading kernel from uboot is unable to read this partition and also time took for flashing is more(nearly 1hr).
    So is there any method to avoid gpt partition and flash with fat and ext4 partition

    Regards

    HI Kaushal 

    Please go through the section "3.3 Generating the eMMC tisdk-tiny-image.img" of https://www.ti.com/lit/an/spracy5/spracy5.pdf 

    Kaushal C said:
    d also time took for flashing is more(nearly 1hr).

    The flashing time depends on the size of the image the restriction is from the dfu tool., There are various factor involved for a slow transfer speed, involvement of usb driver stack ,class driver stack and also in DFU only one end point is getting used which is end point 0.

    Hi Diwakar,

    We are using same DFU tool version for AM62A7 processor and there 7GB of file takes 15mins to flash, but here in DRA821U processor it takes around 1hour. How do we reduce this flashing time.

    What is the SDK you are using for AM62A7?

    Afaik they both use different usb host controller.

    Hi Diwakar

    In AM62A7while flashing .wic image using dfu tool, emmc will automatically formated to vfat and ext4 partition(even if there is no partition table present in emmc), but with DRA821 if there is no partition table exists in emmc we are not able to mount emmc using dfu 0 mmc 0 command.

    This is critical for us, kindly support in this.

    HI Kaushal,

    As said earlier AM62 and DRA821 are using different controller so it is not a ideal comparison.  

    You need to follow the steps mentioned in the TDA4 flashing document.
