Is there a command-line (non-GUI) equivalent for SecureHexAIS_OMAP-L138.exe?
I had written a really nice expect script that called out to slh_OMAP-L138.exe for the initial serial-load of the part, and from there used minicom to issue commands to u-boot and then the Linux command line. All told, it wrapped everything to take a board from completely virgin, all the way through code loaded, production tested, and ready to ship, into one command. Just attach the board, start the script, go have a coffee, come back later to a pass or fail indicator. I can't automate a GUI loader. It's actually quite a bit less convenient to use because of this.
A command-line version of the secure HexAIS serial loader that works just like slh_OMAP-L138.exe did would be a tremendous improvement in my production line workflow.
