How to add particular interface (I2C or SPI) to the trustzone from software in qualcomm MSM8909 platform.

sourabhdas

We are using qualcomm MSM8909 platform. We want to add any of the interface (I2C or SPI) to the trustzone, so that non-secure world couldn't access it. It should only be accessed by the QSAPP apps.

    Hi,

    That platform uses ARMv7-A so the readers of this community might not be the best people to ask.

    In general what you want to do will need the I2C interface hardware to be switchable and then you would also need to be able to provision software into the TEE to control and configure that.

    I don't know if the platform has the necessary hardware and access to the TEE would require support from the device manufacturer.
