Part Number: AM623
Other Parts Discussed in Thread: SK-AM62

Hello TI

   The version of SDK I use:ti-processor-sdk-linux-rt-am62xx-evm-08.06.00.42.

   Using the CPU model of HS-FS, it is found that the CPU startup process into uboot will fail probabilistically, and the probability of the problem is 1%.

   The following screenshot shows the error:

    

   I hope you can help me.

    Before factory team reply, you can try SDK8.6 with TIFS 9.1.08. 

    Then SDK9.1.08 is released on line, you can also copy TIFS and DMSC firmware from there.

    Let's build SDK 8.x u-boot with FW bin (TIFS + DM) from the FW tag 9.1.0.8 (=> SDK 9.1).
    1/. pick up FW binaries (TIFS + DM) from the tag 9.1.0.8
    - TIFS binary
    git.ti.com/gitweb
    - DM binary
    git.ti.com/gitweb

    2/. rebuild u-boot (SDK 8.6) with the TIFS and DM binary from the tag 9.1.0.8

    I'm attaching sample logs I built with Linux SDK 8.6 + FW 9.1.0.8 on SK-AM62 (HS-SE)
    - am62x_8.6_boot_fw-9.1.0.8.log: u-boot/linux boot log
    - am62x_8.6_dm_fw-9.1.0.8.log: dm log
