Hi Titus/Other TI guru
I am trying to do secure boot on the C6748 LCDK without success. Here are the steps that I follow:
1. Use the SecureHexAIS_OMAP-L138.exe file to convert the app.out to encrypted bin
2. the command line I use is: SecureHexAIS_OMAP-L138 -ini omapL138.ini -o app.bin app.out
This step reports success and the app.bin is produced
3. I then use the command(to flash onto NAND flash) sfh_OMAP-L138.exe -targettype C6748_LCDK -flashtype NAND -p COM3 -flash_noubl app.bin
to flash onto the NAND flash. This step also goes through successfully.
4. I change the dip switches to NAND boot and reboot...no success. I don't see the boot screen
I can flash the non-secure app and it works.
Can you please have a look at the attached .ini file to see if it is correct? I am not using a key header file.
However the app should boot with a non-secure key header to my understanding.
Next I am not sure if the DSP C6748 is a secure part on the LCDK. I have got the C6748 LCDK rev A5. Are all DSPs fitted onto
LCDKs secure version of the DSP?
I look forward to an early reply.
Thanks and regardsomapL138.ini
