SK-AM62B: can't boot SK-AM62B

Part Number: SK-AM62B


I received a SK-AM62B, make a boot SD card with SDK8.6 prebuild images, and ensured the tiboot3 is HS version, but no response in console after power up.

The same SD card with replaced GP tiboot3.bin, can boot on GP board. 

Change the boot mode on SK-62B to UART, also no response in console.

is the board dead?

    Hello Tony,
    I ran sanity test using SDK 8.6 package on SK-AM62B board, and SD boot works as expected.
    - AM62x Linux SDK 8.6 package

    - BOOTMODE pin setting for SD boot

    Hong,

    Thanks.

    #1. now I make the SD card with .wic file instead of ./bin/create-sdcard.sh. can boot up. 

    #2. There are 3 tiboot3(tiboot3.bin, tiboot3-am62x-gp-evm.bin, tiboot3-am62x-hs-evm.bin) file in the SD card made of step #1. rename the tiboot3-am62x-hs-evm.bin to tiboot3.bin, can't boot.

    Which source file is the secure version tiboot3.bin?

    Do you make the SD card with .wic image file or with ./create-sdcard.sh?

    Hello Tony,
    I was using the wic image for creating SD card in my testing..
    There is an issue in "create-sdcard.sh" in SDK 8.6, where "tiboot3.bin" is not copied to the SD card by the script.
    I verified SD card booting works on SK-AM62B after I copied "tiboot3.bin" from prebuilt-images folder to the SD card.

    In prebuilt-images folder:
    - tiboot3.bin: HS-FS
    - tiboot3-am62x-gp-evm.bin: GP
    - tiboot3-am62x-hs-evm.bin: HS-SE

    FYI, the "create-sdcard.sh" issue was also in Linux SDK 8.6 for AM64x and 62A.

    Best,
