AM2431: SBL OSPI HS device

Part Number: AM2431


Hello TI,

I have a question regarding HS variant of AM2431,

Device I am working with is custom board with HS version of AM2431, there was NO conversion to HS-SE via burning key to efuses.

With no changes to devconfig Two variant of the sbl are generated:

a) sbl_ospi.Debug.hs_fs.tiimage

b) and sbl_ospi_am243x-lp_r5fss0-0_nortos_ti-arm-clang.tiimage

When changing the device type in devconfig to HS only one binary is generated:

c) sbl_ospi.Debug.hs.tiimage

I have tried flashing all of the binaries and only with the sbl_ospi.Debug.hs_fs.tiimage a) I am able to debug the bootloader in CCS via debuger,
when using b) and c) the soc seems to be stuck in primary bootloader.

When I load the sbl_ospi.Debug.hs_fs.tiimage application image at 0x80000 there seems to be an issue with certification parsing. The condition on line 569
is equal to false and results in unsuccessful boot.

I have tried the application with both GP and HS device types in devconfig.
As mentioned in the sdk only the HS appimage is signed. However both of the cases do not work.

Could you describe what configuration needs to be done for HS-FS devices to successfuly sign/boot appimage.

BR,

Dominik
