Thank you, my bad! Removed linking against libC and now it's ok.

Do you add -lc in your Makefile?
If yes, please delete it, don't use libc.a in RTOS SDK.
We have ported some frequently-used libc apis in SDK, you can refer to include/espressif/esp_libc.h.

Linking against RTOS SDK.

2014-12-11T11:04:49+08:00

Good day

If we don't add main lib to linking we get:
warning: cannot find entry symbol call_user_start; defaulting to 0000000040100000

If we add main lib to linking:
we get some conflicts like
In function `pvPortMalloc': (.text+0x18): multiple definition of `malloc'
In function `vPortFree': (.text+0xec): multiple definition of `free'
or more undefined references to `_sbrk_r' follow

Any help?

Thank you!
