The rk27xx does not use ZSP400 ?
According to the datasheet of rk7xx, the DSP has a eight stages pipeline.
This is not ZSP400 which employs a five stages pipeline.
The eight stages pipeline corresponds to the ZSP 500
And there is a place in the code where i saw a comment saying "initialize ZSP500" or something .....
Now, i am not sure the opcodes for ZSP500 are the same as the ones for ZSP400.
They say they are compatible at the assembly level, but it is still possible that the opcodes are different...
