Other Parts Discussed in Thread: TDA4VM
Tool/software:
Hi
I'm working on a safety project on TDA4VM. I would like to know if the firewall can restrict the bootstrap modules from read/writing?
My concern is the following. Our module deals with write/ read actions in some safety critical areas:
- Region in memory to store the three verifier signatures
- Page Tables
- System Page: The smp->start_addr
If a firewall is set up by the customer bootloader and prohibits our module from writing to these regions, the system will be able to function properly.
Has the firewall an impact on page table or memory?
Thanks for your support
