intel_vvp_usm_init
- Prototype
-
int intel_vvp_usm_init(intel_vvp_usm_instance* instance, intel_vvp_core_base base);
- Description
-
Initialize an IP instance. The initialization stops early if the vendor ID or product ID read at the base address are not a match or if the register map version is not supported. Otherwise, the function proceeds to read and store the IP compile-time parameterization. The instance is not fully initialized and the application should not use it further if returning a non-zero error code.
- Arguments
-
instance - pointer to the intel_vvp_usm_instance software driver instance structure
base - base address of the register map
- Returns
-
kIntelVvpCoreOk (0) in case of success, a negative error code in case of an error
kIntelVvpCoreInstanceErr if the instance is a null pointer
kIntelVvpCoreVidErr if the vendor id of the core is not the IntelFPGA vendor ID (0x6AF7)
kIntelVvpCorePidErr if the product_id does not match with the expected product ID (0x0246)
kIntelVvpUsmRegMapVersionErr if the register map is not supported
