AM620-Q1: DDR margin firmware for customized boad testing

Gibbs Shih
Expert 5665 points
Part Number: AM620-Q1


Tool/software:

Hello, Dear Expert

Because we suffer from thermal issues with LPDDR4 with customized board, so we consider to use "DDR margin firmware" to compare EYE diagram (T EYE) between high temperature and low temperature.

Here are some question

(1) Do we need to rebuild test app (AM62X_TEye_A53_write/read.out) when we change LPDDR4 size.

(2) This is a double check, if we use uart boot mode and run TEye test program, it does not need to flash this test app into any storage(ex:OSPI), isn't?

this uart boot test mode show an use case that download application to LPDDR, and run it directly, isn't?

Thank You Very Much

    Greetings Gibbs,

    1) You can use the same image provided for any DDR size.

    2) Correct, it does not need to be flashed into any external storage. The firmware uses the RAM on the device to test the DRAM.

    Sincerely,

    Lucas

    Hi, Lucas

    Follow read me, I use JTAG to load & execute DDR TEye application is ok

    But I have some problem to execute DDR TEye application w/ uart boot.

    error message,

    [STATUS] ERROR: Application load FAILED !!!ERROR:

    Could you help check it? Do I miss anything?

    Thank You,

    Gibbs

    Greetings Gibbs,

    Your board looks like an HS-FS device, which will require you to sign the application image. This is not unique to the tool, any application for an HS-FS device will need to be signed (and note that the images in the SDK are the "hs_fs" versions that are signed). You can do so with a command like this from the tools directory:

    python ./signing/appimage_x509_cert_gen.py --bin AM62X_TEye_A53_read_unsigned.appimage --authtype 0 --loadaddr 84000000 --key signing/app_degenerateKey.pem --keyversion 1.5 --output AM62X_TEye_A53_read_signed_authtype0.appimage

    On a customer board, this would have to be signed with the customer's key if they have made their part secure enabled. For reference, these details are in the documentation: https://software-dl.ti.com/mcu-plus-sdk/esd/AM62X/10_00_00_14/exports/docs/api_guide_am62x/TOOLS_BOOT.html#TOOLS_BOOT_SIGNING

    Sincerely,

    Lucas

    Hello, Lucas

    I already follow your comment to signed APP image with TI dummy key.

    It can download TEye program by uart, but we still face some error.

    QUESTION :

    (1) I think we do mot need to signed dummy key w/ "sbl_uart.release.hs_fs.tiimage" and "sbl_null.release.hs_fs.tiimage", sin't?

    (2) What reason caused "error_count reached 16" ? It seems the failed reason

    Thank You Very Much

    Greetings Gibbs,

    This is a problem with the UART scripting and not the eye tool itself from what I can see. I'd recommend trying it again or filing a ticket for the SDK folks to look into.

    Sincerely,

    This is feed back form customer

    record here for recording, it seems work

    I am not very sure the reason.
