AM62A3: After flashing KeyWriter binary, no output logs

Part Number: AM62A3

Dear TI,

I refer to below link to generate tiboot3.bin, and flash it to EVM borad, but no any R5 logs output.

https://dev.ti.com/tirex/explore/node?devtools=SK-AM62A-LP&node=A__AckwZeWUyRjXoljXV4PQJw__AM62A-ACADEMY__WeZ9SsL__LATEST&placeholder=true

And I checked the device state through socid.txt, the device is still HSFS.

And I upload the logs of generate keywriter process. Please help to check.

Thanks.

    您好！ 请仅将 Keywriter v09.00与相应的 MCU+ SDK v09_00_00_19一起使用、因为未测试 Keywriter 与每个 SDK 版本的兼容性。 如果您使用正确的 MCU+ SDK 版本后仍然遇到问题、请告诉我。

    Dear TI,

    非常感谢您的支持。

    使用 mcu_plus_sdk_am62ax_09_00_00_19 版本，以上问题可以解决，tiboot3烧写之后，设备变成HSSE的了。

    有一个问题还想请教：

    EVM设备变成HSSE之后，改为正常的emmc启动，没有任何log出来了，现在如何让evm设备能正常启动呢？

    我尝试进入dfu，烧写 hs 的镜像：

    识别到 BootLoader 设备，tiboot3.bin 可以烧写；

    lutao@ubuntu:/home/tony/Work/DSSAD/dfu_flash-2G/DFU_flash_2G/bin/am62axx-evm/hs$ sudo dfu-util -l

    Found DFU: [0451:6165] ver=0200, devnum=27, cfg=1, intf=0, path="3-4.1", alt=1, name="SocId", serial="01.00.00.00"
    Found DFU: [0451:6165] ver=0200, devnum=27, cfg=1, intf=0, path="3-4.1", alt=0, name="bootloader", serial="01.00.00.00"

    然后烧写完，执行" sudo dfu-util -l" 就没有任何设备了，后面的tispl和u-boot镜像就无法烧写，这和之前hsfs的板子不一样，此前都可以烧写的。

    不知问题在哪里，还请帮忙再看下，谢谢。

    Thanls.

    Hi Links,

    上次使用 mcu_plus_sdk_am62ax_09_00_00_19 版本，tiboot3烧写之后，设备变成HSSE的了。

    下一步需要从emmc启动，该如何烧写镜像到emmc里？我这边遇到设备进入dfu无法烧写的问题。

    详细操作如下：

    1.evm板子进入dfu模式

    2.pc烧写镜像，log如下：

    3.tiboot3.bin烧录完，pc执行"sudo dfu-util -l"无设备，无法烧写其他镜像（tispl.bin和u-boot.img）

    EVM设备在HSFS的时候，以上1和2操作完，第3步，pc执行"sudo dfu-util -l"，会出现类似如下的设备：

    这样就可以继续做tispl.bin和u-boot.img烧写，现在无设备，无法进行下一步烧写。

    请问以上问题该如何解决？

    Thanks.
