Hi, there,
I am working on a SAM7X project with yagarto.
gcc generates all the obj files without problem. but it complains when it comes to link, compile msg says a few file IO function missing from the libs. here's the detail,
make all
arm-elf-gcc -g -Os -v -lgcc -nostartfiles -Wl,--gc-sections -T"./flash.lds" -o bin/MINIBOT_CCB-at91sam7x256-flash.elf obj/flash_cpu_a.o obj/flash_os_cpu_a.o obj/flash_cstartup.o obj/flash_bsp.o obj/flash_lib_mem.o obj/flash_lib_str.o obj/flash_os_cpu_c.o obj/flash_os_dbg.o obj/flash_os_dcc.o obj/flash_os_core.o obj/flash_os_flag.o obj/flash_os_mbox.o obj/flash_os_mem.o obj/flash_os_mutex.o obj/flash_os_q.o obj/flash_os_sem.o obj/flash_os_task.o obj/flash_os_time.o obj/flash_os_tmr.o obj/flash_app.o obj/flash_Console.o obj/flash_flashdev.o obj/flash_fpga.o obj/flash_misc.o obj/flash_motor.o obj/flash_Protocol.o obj/flash_xmodem.o obj/flash_MiniIp.o obj/flash_can.o obj/flash_emac.o obj/flash_dm9161.o obj/flash_pio_it.o obj/flash_pio.o obj/flash_rstc.o obj/flash_tfs.o obj/flash_tfsapi.o obj/flash_tfsclean.o
Using built-in specs.
