Stack error
stack_protect.c:65 Stack Check Failed
It's a stack overflow issue. Usually local array overflow will cause this crash. If you have added
-fstack-protector during compilation, the stack checker will report this crash which shows that some of the functions may have stack overflow or stack corruption.
When a stack is corrupted/overwritten by other tasks, it can also cause other exceptions if -fstack-protector is not added.
1.&&&&&& V.f, check the call stack
2.&&&&&& D.dump SP, check the stack
3.&&&&&& Check assembly in detail to see which value is wrong, and whether the content on stack is corrupted.
4.&&&&&& Check whether 128 padding 0xF8 is corrupted in stack.

Read code to find the error fatal reason, check call stack and input variables to see why error fatal happened.
Normally a SW bug.
Error fatal in protocol stack modules
The error fatal in protocol are handled by modem team. E.g:

General flow:
1.&&&&&&&& Decode the route ID per the decomposition table of a specific NoC to get values for the InitFlow, TargFlow, TargSubRange, SrcId.PID, SrcId.BID, SrcId.MID, and SeqId parameters.
2.&&&&&&&& Look up master information (route ID composition of a specific NoC) from the InitFlow value.
3.&&&&&&&& Look up slave information (route ID composition of a specific NoC) from the TargFlow value.
4.&&&&&&&& Look up the source bus, port, and master by using SrcId.BID, SrcId.PID, and SrcId.MID values, respectively.
CNOC Error: 0x Source: 0x05 Destination: 0x29 MID: 0x0F BID: 0x02 PID: 0x03
InitFlow qxm_snoc/l/0
TargetFlow qhs7/T/mss_cfg
Master ID A53 cluster
BID: 0x02 //BIMC
PID: 0x03 //A53 cluster
For the mss_cfg, check from CNOC HDD, its base address is 0xfc800000
qhm0_rpm_M2 [0xfdxfc800000]& qhs7_mss_cfg& WR& 1 bytes& Req 81.3 ns
And the offset is 0x80040 from ERRLOG3.
CNOC ERROR: ERRLOG3 = 0x
So the final address is 0xfc800000 &#43; 0x80040 = 0xFC880040
Check from ipcat, this address is MSS_QDSP6SS_NMI.
MSS_QDSP6SS_NMI
<span style="color:#xFC880040
Need check why APPS access MSS_QDSP6SS_NMI and cause the NOC error.

4.&&&&&& Run rpm_parse_faults.cmm
5.&&&&&& v.f, check call stack
6.&&&&&& d.l PC
7.&&&&&& Check why it tries to access this AHB bus
Bus error occurs when AHB
receives an error response from a bus slave – RPM does not have access permission.

<span style="color:#.602256: rpm_error_fatal (lr: 0x0010c7b) (ipsr: 0x) – “unknown interrupt 73”
RPM receives the notification interrupt from HW when a NON secure WD bite occurs within APPS to preserve RPM states. This is not a RPM error. Need to check the non-secure WD from AP.
Not an error in RPM.

Waiting for GCC_BIMC_DDR_CPLL_CMD_RCGR bit0 to clear when APPS requested new BIMC freq from 547.2MHz to 777.6MHz.
Mostly it’s a HW issue. Check with HW together.

3.&&&&&& Check railway.txt
Follow Railway.rail_state[n].voter_list_head to walk through the voters.
Mostly it’s SW reasons make RPM can’t enter vdd_min.
