Hi OP-TEE experts,
I am working on to integrate OP-TEE secure OS with u-boot on ARMv7 and came across following question
that I need to clarify:
- It seems that optee-os doesn't save u-boot context at its entry point during its initialization.
o Like registers r0-r12, sp etc.
- Is it the responsibility of boot-loader (u-boot in my case) to save its context, pass
control to optee-os and then retrieve context after optee-os returns control back to boot-loader?
If someone can help clarify this it would be very much appreciated.
Thanks and regards,
Sumit
Hi,
With goal of understanding ARM TrustZone and security feature, I
started with trying to setup OP-TEE on ARM FVP,
I followed the steps:
https://github.com/OP-TEE/optee_os
After all build over linux is not booting on VP. It stuck with:
it show
PEI 886ms
DXE 84 ms
BDS 5ms
Total Time = 976 ms
<=== No more activity beyond that
Any pointer would be helpful.
Thanks,
Chetan Nanda
