OMAPBootrom¶
Documentation¶
The droiddevelopers website has some information on trying to use bugs run free software on several Motorola devices.
That website has many information:
- It has documentation on the structure of signed MLOs
TODO:
- Read droiddevelopers more to understand restricted boot better.
- Also the OMAP wiki might have some information on OMAP restricted boot.
- Also look if there is substancial information in the Technical Reference Manual (TRM) about fuses but that's unlikely.
Code¶
- As march 2020, there are no fuses driver or code for any OMAP in either u-boot, Barebox, Linux, or crucible.
- U-boot documentation mention TI tools that have to be obtained after signing an NDA
- TODO: check if chipsec has infos on OMAP fuses
Possible attacks¶
- Even if it's unlikely, once we understand the OMAP restricted boot better, we could check if some devices are signed but not in enforcing mode.
