AM4372: VBAR CP15 c12 register

Part Number: AM4372

Hi all,

I'd like to prepare multiple vector tables and create a mechanism to switch the tables according to the mode.

Is it possible by using VBAR(CP15 c12 register) above?

I designed it based on the following starterware.

C:\ti\pdk_am437x_1_0_6\packages\ti\starterware

Best regards,

Hi,

We will implement three modes in the application program.
These modes may change during program execution.
I would like to prepare a dedicated vector table for each mode.
For example, when using GPIO interrupt, I want to change the jump destination for each mode.

Best regards,
Sasaki

I have asked the RTOS team to comment. They will respond here.

Sasaki,

I'm unsure on how this can be implemented. Will need to check and post back here if multiple vector tables can be prompted based on the mode selected on the A9.

Sasaki-san,

To help out further, please see this link stackoverflow.com/.../relocate-the-arm-exception-vectors I think it has information that will be useful for your implementation.
