AM623: AM62 Dev-boot mode

MASAKI OOTAKA

Part Number: AM623

Tool/software:

I have a question about boot mode of AM62.
According to the TRM, there is a description about Dev-boot Mode.

However, in the other E2E, it says that Dev-Mode cannot be used regardless of GP/HS-FS products.

https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1398156/am625-unlock-hs-fs-device-to-use-with-ccs/5425576?tisearch=e2e-sitesearch&keymatch=AM62%252520SBL%252520Initialization%252520HS-FS#5425576

How can I understand this?
・Is this a misstatement of TRM?
・Is it possible to use Dev-boot Mode in the future?

There is no mistake in the TRM, the SoC supports No boot/Dev boot mode, it's just that support for the same is not there in MCU+SDK, due to which you can not initialize the SoC in the Dev boot mode for AM62x devices. This is supported in AM64x: https://software-dl.ti.com/mcu-plus-sdk/esd/AM64X/10_01_00_32/exports/docs/api_guide_am64x/EVM_SETUP_PAGE.html#autotoc_md31

There is no plan to support Dev-boot mode for Am62x in the future, you can use SBL NULL for any initialization purpose.

Best regards,

Meet.

Thank you for the answer.
I am considering using AM62. (Cannot change to AM64)

I recognize that AM62 is not supported in MCU+SDK.
Nonetheless, does that mean it is mentioned in the TRM about No boot/Dev boot mode?

Also, let me check again, do you mean that No boot/Dev boot mode cannot be used with AM62 because it is not possible to execute GEL scripts?

Best regards,

The SoC supports this boot mode so TRM mentions the same.

Software support for this boot mode or initialization using GEL script in this boot mode is not there in AM62x MCU+SDK.
