Hello everybody
I designed a multi Microblaze
processor system with four Microblaze processors using the board ML510. the four processors
connects to each other with an FSL busses and share the same console
"RS232" which is connected to the first processor "Microblaze_0" through
its "PLB_0" bus. I used three PLBv46-to_PLBv46 bridge to connect the
PLB_0 to the other three busses "PLB_1", "PLB_2" and "PLB_3" to let the remaining processors to see the adress of the perioheral "RS232". In order to synchronize the four processors I used the Xilinx mutex core with four SPLB port to connect the four PLB buses of the four processors.
The problem occured in the driver of the mutex core. The file xparameters.h for the first and second processors contains the definitions of the driver parameters of the mutex core, but the file xparameters.h for the third and fourth processors don't have.
1. xparameters.h for microblaze_0 wich connected to PLB_0

Could you help me to solve this problem?
