I'm trying debug the board ECB_AT91, that have a AT91RM9200 arm.

I can´t probe an 8MB sdram, MT48LC4M16A2 from micron.

At Telnet client:

Open On-Chip Debugger
>flash probe 0
Could not probe bank
probing failed for flash '#0' at 0x00000000

My config file:

telnet_port 4444
gdb_port 3333
interface ft2232
ft2232_device_desc "Amontec JTAGkey A"
ft2232_layout jtagkey
ft2232_vid_pid 0x0403 0xcff8
jtag_speed 2
reset_config trst_and_srst
jtag_device 4 0x1 0xf 0xe
jtag_nsrst_delay 250
jtag_ntrst_delay 250
daemon_startup reset
target arm920t little run_and_init 0 arm920t
run_and_halt_time 0 5000
target_script 0 reset temp.ocd
working_area 0 0x20000000 0x40000 nobackup
flash bank cfi 0x00000000 0x800000 2 2 0

I need help, can't guess what's the problem.
