MCU-PLUS-SDK-AM263X: Crypto Examples for am263x-lp

Wenkai
Prodigy 180 points

Part Number: MCU-PLUS-SDK-AM263X

Hello,

The latest SDK release 8.05 examples have included security/crypto drivers - but only for the board am263x-cc. Can these crypto examples also work for am263x-lp board? 

And how about HW accelerator for CRC driver examples / APIs? I didn't see any in this release.

Thanks,

Wenkai

    Of course. The crypto accelerators will work for AM263x-LP as well. For now the examples do not have support for the same. We will add those. If you require any help in porting the same, we can help on the same.

    We do have CRC supported in DTHE but the driver and example for the same is still under development.

    Hi Aakash,

    I tried to run this example on am263x-lp using sbl_qspi bootloader but it stuck at the beginning of the application like this:

    Starting QSPI Bootloader ... 
[BOOTLOADER_PROFILE] Boot Media       : NOR SPI FLASH 
[BOOTLOADER_PROFILE] Boot Media Clock : 80.000 MHz 
[BOOTLOADER_PROFILE] Boot Image Size  : 26 KB 
[BOOTLOADER_PROFILE] Cores present    :

[BOOTLOADER_PROFILE] SBL Total Time Taken             :       1950us 

Image loading done, switching to application ...
[CRYPTO] SHA example started ...

    Any idea what could be wrong?

    Thanks,

    Wenkai

    Hi Wenkai,

    Is that so ? Let me replicate the issue on my end as well. Which release are you using by the way ?

    I was using mcu_plus_sdk_am263x_08_05_00_24, which just has security/crypto drivers with it. And the example is: examples\security\crypto\dthe_sha\crypto_sha_256

    I suspect that HSM firmware couldn't bypass the firewalls to make crypto modules available.

    Thanks,

    Wenkai

    Hi Wenkai,

    I understand the problem. Can you check the device version as well ?

    You can use this FAQ for the same - https://e2e.ti.com/support/microcontrollers/arm-based-microcontrollers-group/arm-based-microcontrollers/f/arm-based-microcontrollers-forum/1170785/faq-mcu-plus-sdk-am243x-how-to-identify-if-the-device-is-gp-device-or-hs-device

    Make sure to follow the steps for AM263x.

    Hi Aakash,

    I checked device type and it is HS-FS. Can you find anything wrong from following detailed device info? I noticed Cust MPK Hash is all zeros - is it normal?

    Hi Wenkai,

    Security Examples for am263x is only expected to be functional on these version of device type.

    Make note of the PGVer, ROMVersion and the r5 ROM Version.

    Please request for the new PG of AM263x or an upgrade.

    Snippet for the same is here -

    Cust MPK Hash is normally zero. It is only available if the MPK is flashed with OTP key-writer tool.

    Hope this helps.

    How do I request for a new PG or an upgrade? Do I need to buy a new LaunchPad board?

    Thanks,

    Hi ,

    Can you reach out to Murphy, Sean <s-murphy1@ti.com> or Kumar, V C <vckumar@ti.com> based on your requirement ?

    They would be best supportive for such cases.
