Hi,
I am wanting to have the boot image for a L138 device encrypted to AES-128. I understand that using AIS boot mode supports encryption, and we are currently booting fine with unencrypted AIS boot images. From my understanding, I need a "High Security" device, and the SecureHexAIS tool in order to implement encryption (Processor Security User Guide SPRUGQ9, Page 27). I have installed the program, but there is very little documentation describing what to do in order to implement the encryption. Additionally, the only files I see in the directory after installation are:
C674x_OMAPL1x_Generic_Security_Flash_Boot_Utils.tar.gz
Manifest_Secure_C674x_OMAP-L1x Flash and Boot Utils.pdf
OMAPL138_C6748_Generic_Security_Users_Guide_v1.0.2.pdf
And uninstall.exe
I unpacked the tar.gz (What kind of installer doesn't unpack files anyways?) and was able to find the tool, but when using the SecureHexAIS_OMAP-L138.exe with the example ini. I receive an error stating that the program could not find key_hdr_sha256_enc.bin.
I feel like somehow I downloaded a incomplete/broken toolset, especially since I had to unpack the files. Any thoughts/ideas? I am new, so it may be entirely my fault.
Thanks,
Joe
