I would like try to make run two different bare metal application on both cpus of the Zynq 7010.
In order to do this, I tryed to create a new fsbl with the default template in the SDK integrated in Vivado (Release version 2013.4). Then I create the two Helloword application for both core of the Zynq.
In the follow of this message I paste the code of the main procedures:
Cpu0:
#define sev() __asm__("sev")
#define CPU1STARTADR 0xfffffff0
#define COMM_VAL (*(volatile unsigned long *)(0xFFFF0000))
//void print(char *str);
int main()
{
// init_platform();
tprint("hello!
r");
//Disable cache on OCM
Xil_SetTlbAttributes(0xFFFF0000,0x14de2); // S=b1 TEX=b100 AP=b11, Domain=b1111, C=b0, B=b0
COMM_VAL = 0;
print("CPU0: writing startaddress for cpu1
r");
tXil_Out32(CPU1STARTADR, 0x00200000);
tdmb(); //waits until write has finished
tprint("CPU0: sending the SEV to wake up CPU1
r");
tsev();
tprint("CPU0: Hello World!
r");
tCOMM_VAL = 1;
return 0;
}
Cpu1:
#define COMM_VAL (*(volatile unsigned long *)(0xFFFF0000))
int main()
{
//Disable cache on OCM
tXil_SetTlbAttributes(0xFFFF0000,0x14de2); // S=b1 TEX=b100 AP=b11, Domain=b1111, C=b0, B=b0
// init_platform();
//
// print("Hello World
r");
twhile(COMM_VAL == 0){};
tprint("CPU1: Hello Word!
r");
tCOMM_VAL=0;
return 0;
}
After, a build of all projects, in order to create the "*.bit" (using the "Xilinx Tools" menus) to be loaded in the sd or flash, in both cases my project does not works.
Do I have to change something in the fsbl or in another part of this project?
Thank you so much for your support,
Claudio
