cortex m23 execute function in ram result in hardfault

saxon mark

Hello everyone:

I'm trying to leverage the __attribute__((section(.ramfunc))) to execute function in RAM. However, a handfault error happened when it execute the instruction in the ram address.

My board is SAML11 Xplained Pro,Cortex-M23 core and the excution is  in secure world.

The code runs in Thumb mode and the bx address is odd.

Has anyone met the same problem?
