If fpu/audio is disabled, to access fpu/audio registers will cause exceptions.

So, we need to check if fpu/audio is enabled or not as target is halted. If fpu/audio is disabled, as users access fpu/audio registers, OpenOCD will return fake value 0 instead of accessing registers through DIM.

nds32_restore_context()

int nds32_restore_context

(

struct target *

target

)

Restore the processor context on an Andes target.

The full processor context is analyzed to see if any of the registers are dirty on this end, but have a valid new value. If this is the case, the processor is changed to the appropriate mode and the new register values are written out to the processor. If there happens to be a dirty register with an invalid value, an error will be logged.

Parameters

target

Pointer to the Andes target to have its context restored

Returns

Error status if the target is not halted.
