Tool/software: Linux
I have been evaluating the AM4378 HS EVM. Using the TI Linux SDK I have to securely build and load UBoot via the UART to perform boot up to UBoot. However I don't see that the subsequent step of booting into Linux is secure. I would have expected UBoot to check a signature of the Linux image prior to execution.
For the UBoot I had to alter the Rules.make to use the HS variant and tell it where I had placed the TI_SEC_DEV_PKG. I can't see any options like this for Linux.
So my question is, does the SDK secure the bootloader to Linux kernel step? If so, how?
Many thanks,
Daniel
