pb installing RedBoot on AT91EB40

Hello all,

	following the Redboot user guide, I'm trying the
rdi mode with gdb, using a KeySpan USB to Serial converter;

(gdb) imac:~ kalou$ ls -l /dev/*Key*
crw-rw-rw-   1 root  wheel    9,   5 Dec 11 01:42 /dev/cu.KeySerial1
crw-rw-rw-   1 root  wheel    9,   4 Dec 11 01:34 /dev/tty.KeySerial1

imac:~ kalou$ /usr/local/bin/arm-elf-gdb Desktop/redboot_RAM.elf

(gdb) tar rdi s=/dev/tty.KeySerial1
Could not open device "s=/dev/tty.KeySerial1"
(gdb) tar rdi s=/dev/cu.KeySerial1
Could not open device "s=/dev/cu.KeySerial1"

Am I doing something obviously wrong ? I checked that the Serial is ok, using zTerm, I get the Angel debug monitor fine;

xxAngel Debug Monitor (serial) 1.04 (Advanced RISC Machines SDT 2.11a) for AT91 EB0x (1.01)
Angel Debug Monitor rebuilt on Sep 14 1998 at 14:52:22


9600 8N1

When I open gdb, zTerm has been closed first.

Any tips ?
