Hello,
I'm wondering what the correct way to mask non secure interrupts is, on entering secure world on an ARMv8-M processor, with Main and Security extensions. The scenario I have is as follows:
The SOC has 1 M33 core. I have a non secure OS that…
How to run TF-M on keil M23/M33 fvp?
I have noticed there are also M23/M33 fvps under Keil IDE related path. Whether there is some difference about the startup parameters to run TF-M on Keil fvps compared to DS-5 fvps?

Transition to secure monitor flow on ARMv8
Hi everyone,
Wherever I go on internet, the thing I read is that when SMC instruction is executed an exception is generated, it takes you to the highest exception level (EL3) where secure monitor is running.
In ARM v8 vector table, given on ARMv8-A architecture…

关于ARMv8中不同Security状态下异常向量表的问题
Hi，各位专家：
在ARMv7-A架构中，共有四张异常向量表，即Secure状态下的exception table, Non-Secure状态下的exception table，Monitor Mode下的exception table,以及hypervisor模式下的异常向量表，因为在不同Security状态下，VBAR寄存器是banked，所以它可将不同security状态的异常向量表分开,即Secure状态和Non-secure状态对应不同的exception table.…
