When I try to build this demo from the download I get linker errors such as: mallocr.c:(.text+0x2c): undefined reference to `_sbrk_r’ mallocr.c:(.text+0x3c): undefined reference to `_sbrk_r’ mallocr.c:(.text+0x48): undefined reference to `_sbrk_r’ and stdio.c:(.text+0x6e): undefined reference to `_lseek_r’ stdio.c:(.text+0x86): undefined reference to `_write_r’ This seems to refer to problems with missing code in newlib. Can anyone point me to the resolution of this? I am using the WINARM (GCC compiler). Thanks

Looks like the GCC library is not defined. Dont know why it is trying to use read and write in any case. Maybe set configUSE_TRACE_FACILITY to 0 in FreeRTOSConfig.h. You need to define the library used. Best to download yagarto and use that instead of winarm.

OK, I’ll try that. Thanks.
