How to enable TZASC (TrustZone) on N1SDP?

icegrave0391

Hi,

I'm facing an issue that makes me very confused: I would like to enable TZASC on N1SDP. However, I found that Trusted-Firmware does not include such code to configure secure memory in the file n1sdp_security.c (https://github.com/ARM-software/arm-trusted-firmware/blob/master/plat/arm/board/n1sdp/n1sdp_security.c):


/*
 * TZC programming is currently not done.
 */
void plat_arm_security_setup(void)
{
}

Therefore, I want to know whether N1SDP supports TZASC hardware extensions such as TZC-400. If so, I want to know how to enable it.

Thanks in advance for your help,

Regards,

    According to me to enable TZASC (TrustZone) on N1SDP, follow these steps:
    >>Access the system's secure boot firmware settings.
    >>Please allow the TZASC feature to be enabled.
    >>You can configure the TZASC registries according to your security requirements.
    >>Reboot the system by saving your settings.
