It seems that the address 0x4000e1b2 does not exist in Main.O as it ends on 0x4000b211... Anyone know any background details on how I can narrow down the root cause. Thank you!!
As for addtional detail, it seems in https://www.espressif.com/sites/default ... ses_en.pdf on page 3/4 that this may be more of a ROM issue?
Update: It seems that I found a feed of the obj dump on google.

I think my program is crashing within a memset call.. Maybe one of my alloc's is sliently failing cauing memset in my userland code to trigger this exception?
https://0x04.net/~mwk/doc/xtensa.pdf <-- I then found this and looked up s32i.n and found this on page 78/662
Code: Select all
Table 4–27. Code Density Option Instruction Additions
Instruction1 Format Definition
ADD.N RRRN Add two registers (same as ADD instruction but with a 16-bit encoding).
ADDI.N RRRN Add register and immediate (-1 and 1..15).
BEQZ.N RI16 Branch if register is zero with a 6-bit unsigned offset (forward only).
BNEZ.N RI16 Branch if register is non-zero with a 6-bit unsigned offset (forward only).
BREAK.N2 RRRN This instruction is the same as BREAK but with a 16-bit encoding.
L32I.N RRRN Load 32 bits, 4-bit offset
MOV.N RRRN Narrow move
MOVI.N RI7 Load register with immediate (-32..95).
NOP.N RRRN This instruction performs no operation. It is typically used for instruction alignment.
RET.N RRRN The same as RET but with a 16-bit encoding.
RETW.N3 RRRN The same as RETW but with a 16-bit encoding.
S32I.N RRRN Store 32 bits, 4-bit offsetif seems when executing S32I.N RRRN Store 32 bits, 4-bit offset it triggers the issue, This may be more information then I need but I think I have an idea of what is triggering it but I am uncertain on how to locate the calling function without laying a bunch of printf's everywhere. Anyone know how to get a callstack or get addtional details?
- Img of crash
Update2:
So I appended this check to each of my alloc's before the memset's got to them and it seemed to have resolved the issue.
Code: Select all
if (FormatedHTMLPage == 0x0)
{
os_printf("[%s][%s][%d] - Unable to Alloc memory, exiting\r\n", __FILE__ ,__func__, __LINE__);
return;
}
The larger issue is I only have about 25k of heap to have a client connect via WPA-PSK2 and then send it a detailed webpage.
The page itself is almost 8k in side. Anyone know of an easy way to send this waypage with dynamic configurations inside?
The way I have it now is its loaded in flash and it reads it into a GlobalVar at the start. Yes sadly this takes a var kinda like this
char webpage[8192] = SPiRead(WebpageInSPIRom)
Then I have to allocate another for sprintf to then change my variables before I shoot it off to the client.
Problem is thats 16k raw just to format the data in memory. Any pointers would be greatly appreciated!

System halt!Anyone know how to see the function call at address's greater then 0x40100000? With this new EPC1 value it seems its assigned to the mapping of IRAM1.. Am I on the right track, should I objdump the Main.o and review the offset 0x1074 within?
Any pointers in the right direciton would be greatly appreicated.
