- Thu Aug 20, 2015 10:43 pm #26640 This exception means an attempt was made to read from an address space that is invalid. The program counter where the exception occurred was 0x4000deed and the address it tried to read was 0x0000000f. Without knowing your application, this is about all we can tell from the exception posted.

Thank for response.
I use [Ubuntu 14.04 LTS 64bit] and [pfalcon/esp-open-sdk] . I made exactly all the steps in https://github.com/Spritetm/esphttpd

When build the code run: make. I see a warning that appears in the last compile:
-------------------
LD build/httpd.out
/home/sunny/esp-open-sdk/xtensa-lx106-elf/lib/gcc/xtensa-lx106-elf/4.8.2/../../../../xtensa-lx106-elf/bin/ld:ldscript_memspecific.ld:1: warning: redeclaration of memory region `irom0_0_seg'
FW firmware
-------------------
Is this error related to the Error: Fatal exception (28) ?
