hi again… even tried to get a connection via JTAG… but that was not successful, too. Seems like the board got damaged, maybe by plugging and unplugging the USB… Now next thing I’ll do is to mount a new SAM7S.

Hi! I’ve got the same problem with my Olimex board. However I started using Wiggler JTAG Interface and it let’s me program the board without problems. I also realised that on some occasions SAM-BA seems to recognize the board when I use DBGU connection - but it happens at random… I think You couldn’t have damadged the board - it’s something else, maybe an error at developement stage in Olimex…
Cheers
Hi,
I am new to the ARM world and microcontrollers. :oops:
I have a SAM7-P64 board and a Linux box. The sam7utils-0.0.3 with the Blinking_LED.BIN worked fine, thus the board is o.k.
I have the GNU-ARM compiler set, and I try testing on the Blinking_LED source project. However, the resulted file is different in size from the Blinking_LED.BIN and also does not work.
I used:
arm-elf-gcc -mcpu=arm7tdmi -c -O3 -Wall -o test.o main.c system.c
arm-elf-ld -A arm7tdmi -b binary -o test.elf test.o
arm-elf-objcopy test.elf -O binary test.bin
Anyone with some ideas?
