Tool/software:

Hi,

I'm using MCU-PLUS-SDK-AM263X v10.0.0.35.

I'm having some issue while trying to load and run an application code on my HF-SE board.

The problem is present only when I decide to enable the encryption of the application code, while is all ok when I try to load just a signed application code (with no encryption enabled).

Please, can you confirm that the application code encryption is supported by this MCU-PLUS-SDK version?

Thanks.

Hi Vanni,

Could you please share the issue screenshot or the console log text, meanwhile I will look into the encryption support in SDK.

Hi Nilabh,

the image above is a screenshot of the debug session. The highlited row is the failure point. This is the code of the library function 'Bootloader_parseAndLoadMultiCoreELF'. The application code in Flash is encrypted, but the library function seems to ignore this.

Regards,

Vanni

Sorry, I checked the application code format and it was incorrect. Now I've flashed the code in ELF format but the SBL is still not able to load it. The following image shows where the code retuens an error.
