Hi I'm starting with ecos and LPC2124 ARM7. I've downloaded ecos as stated on the website for cygwin, choose template "Keil eveluation board MCB2100" as compatible with my set, package default (but checked also kernel and minimal), have my own program, trying to build and got errors:
'rm-elf-gcc: unrecognized option `-nostdlib /cygdrive/d/apps/gnuarm/bin/../lib/gcc/arm-elf/3.4.3/../../../../arm-elf/lib/crt0.o(.text+0x0):../../../../../../newlib-1.12.0/newlib/libc/sys/arm/crt0.S:36: multiple definition of `start' first_install/lib/vectors.o(.text+0xc4):/home/xpurogo/ecos/ecos-3.0/packages/hal/arm/arch/v3_0/src/vectors.S:353: first defined here /cygdrive/d/apps/gnuarm/bin/../lib/gcc/arm-elf/3.4.3/../../../../arm-elf/bin/ld: address 0xc548 of a.out section .bss is not within region ram /cygdrive/d/apps/gnuarm/bin/../lib/gcc/arm-elf/3.4.3/../../../../arm-elf/bin/ld: section .bss [00007cb4 -> 0000c547] overlaps section .text [00000040 -> 0000c303] /cygdrive/d/apps/gnuarm/bin/../lib/gcc/arm-elf/3.4.3/../../../../arm-elf/lib/crt0.o(.text+0xf4):../../../../../../newlib-1.12.0/newlib/libc/sys/arm/crt0.S:206: undefined reference to `__bss_start__' /cygdrive/d/apps/gnuarm/bin/../lib/gcc/arm-elf/3.4.3/../../../../arm-elf/lib/crt0.o(.text+0xf8):../../../../../../newlib-1.12.0/newlib/libc/sys/arm/crt0.S:206: undefined reference to `__bss_end__' collect2: ld returned 1 exit status arm-elf-objcopy: 'a.out': No such file arm-elf-objdump: 'a.out': No such file ./m: line 4: $'arm-elf-size\r': command not found ./m: line 5: $'\r': command not found ./m: line 6: $'\r': command not found Using different toolchains from gnuarm i've got few similar errors from linker. My program i'm trying to build using script: arm-elf-gcc -g -Os -Ifirst_install/include test1.c -Lfirst_install/lib -Ttarget.ld -nostdlib arm-elf-objcopy -O ihex a.out a.hex arm-elf-objdump -D a.out > a.lst arm-elf-size where "first_install" is directory created by ecos config tool, target.ld linker script is generated as well. Program is very simple. -- Before posting, please read the FAQ: http://ecos.sourceware.org/fom/ecos and search the list archive: http://ecos.sourceware.org/ml/ecos-discuss
