Can we use a particular device in secure and non secure mode simultaneously without switching between modes?
Can it be done by by configuring/partitioning the address space of device ?
depends on the design of the peripheral
if it has already multiple registers then there is nothing to configure in the peripheral since those different addresses are mapped by the security regions
if the peripheral does not have distinct registers then it will most likely need to be configured in order to support this secure/non secure access
if not, then you would need support in the driver to handle this secure non secure access
Thanks a lot Diya,
