Problem with ARM 7 and Eclipse

Posted by Lukas Alves on September 15, 2010
I'm using Eclipse to compile FreeRTOS demo application for ARM7 and Eclipse (ARM7_AT91SAM7X256_Eclipse) but when I build it one error occur:

cc1.exe: error: unrecognized command line option "-fno-dwarf2-cfi-asm"

I tried to comment the -fno-dwarf2-cfi-asm CFLAGS and it works, compile without errors. But I don't know if I can do this. When I try Run the demo using the OpenOCD Programmer a message appears saying:

terminate, exit value: -1073741515

Can any one help me with configuring the eclipse. I tried to follow the FreeRTOS instructions but it doesn't work.

The instructions on the main FreeRTOS pages are out of date, Eclipse and OpenOCD have moved on since. You could try http://interactive.freertos.org/entries/206059-windows-eclipse-arm-toolchain-tutorial-for-beginners-in-german-based-on-stm32f103-cortex-m3 if you speak German or use Google translation.

edwards3 I tried to use google translator and it works well. But I'm using OLIMEX AMR-USB-OCD and SAM7-EX256 Olimex development board (AT91SAM7X256 ARM7TDMI-S MICROCONTROLLER) that is different from the Cortex M4 that you use, and the tollchain seems to be different.
I need the FreeRTOS to complete one school project, that I need the arm board connected to internet via ethernet, and FreeRTOS.

Can anybody help me configuring eclipse for FreeRTOS and OLIMEX development board?
