non correctable error in SRAM

Hello,

using the SPC56EL70

I successfully injected correctable faults in RAM, but after injecting the uncorrectable one with following lines:

SPP_MCM.ECR.R=(0x20|0x02); //activate correctable and non-correctable reportings

SPP_MCM.EEGR.R= 0x0220; // inject uncorrectable error

*((uint32_t *) 0x40001000) = PATTERN;

SPP_MCM.EEGR.R= 0x0000;

When I access the location, I get trapped in

void osalSysHalt(const char *reason) {

osalSysHalt:

0x00002AB0: 18 21 06 F0 E_STWU R1,-0x10(R1)

0x00002AB4: 00 80 SE_MFLR R0

0x00002AB6: D5 01 SE_STW R0,0x14(R1)

0x00002AB8: D2 31 SE_STW R3,0x8(R1)

osalIsrDisable();

0x00002ABA: 79 FF FD F7 E_BL 0x000028B0

osal_halt_msg = reason;

0x00002ABE: 70 08 E0 00 E_LIS R0,0x4000

0x00002AC2: C2 71 SE_LWZ R7,0x8(R1)

0x00002AC4: 01 06 SE_MR R6,R0

0x00002AC6: 54 E6 08 B8 E_STW R7,0x8B8(R6)

while (1)

;

0x00002ACA: E8 00 SE_B 0x00002ACA

0x00002ACC: 00 00 SE_ILLEGAL

0x00002ACE: 00 00 SE_ILLEGAL

with reason 0x3340 -> clock failure.

What am I doing wrong?

Hello Simon ,

Could you check the stack ?

i think that when you inject a non-correctable error .. you are going to a SAFE mode.

are you resetting ?

Best Regards
