MPC5777M S32DS-2017R1
I have a shared-memory code of multcores, but it only works in debug mode. When power on again, I cann't work.
I transplant code from Example S32R274 multi-core shared memory - S32DS Power v1.2
Hi,
as I can see in your linker file and in startup code, you don't initialize shared SRAM. This is mandatory because the SRAM is in random state after power-on which leads to double bit ECC errors. If you then access such SRAM, machine check exception is triggered.
This is from startup.s:
You need to run this code also for shared memory.

int main(void)
{
int counter = 0;
SysClk_Init();
LINFlexD_1_Init();
TransmitCharacter(0x61);
Z4_busy_flag = 1;xcptn_xmpl (); /* Configure and Enable Interrupts */
/* Loop forever */
for(;;) {
TransmitCharacter(0x61);
counter++;
}
}
when I removed "Z4_busy_flag = 1;", the code works fine in both mode. It seems like that the program can't access the Z4_busy_flag, when power on again.
