OpenOCD AT91SAM7S256

[blan]

hi,

ich wollte jetzt endlich mal meine Olimex Entwicklerplatine mit einem
AT91SAM7S256 ausprobieren. Ich benutze für JTAG einen Wiggler und
OpenOCD. Ich hab mich an die Anleitung gehalten:
http://www.mikrocontroller.net/articles/AT91SAM7S_mit_OpenOCD_programmieren

Meine OpenOCD-Konfiguration:


#define our ports

telnet_port 4444

gdb_port 3333



#commands specific to the Amontec JTAGKey

interface parport

parport_port 0x378

parport_cable wiggler

jtag_speed 0

jtag_nsrst_delay 200

jtag_ntrst_delay 200



#reset_config <signals> [combination] [trst_type] [srst_type]

reset_config srst_only srst_pulls_trst



#jtag_device <IR length> <IR capture> <IR mask> <IDCODE instruction>

jtag_device 4 0x1 0xf 0xe



#daemon_startup <'attach'|'reset'>

daemon_startup reset



#target <type> <endianess> <reset_mode> <jtag#> [variant]

target arm7tdmi little run_and_init 0 arm7tdmi_r4



#run_and_halt_time <target#> <time_in_ms>

run_and_halt_time 0 30



# commands below are specific to AT91sam7 Flash Programming

# ---------------------------------------------------------



#target_script specifies the flash programming script file

#target_script 0 reset script.ocd



#working_area <target#> <address> <size> <'backup'|'nobackup'>

working_area 0 0x40000000 0x4000 nobackup



#flash bank at91sam7 0 0 0 0 <target#>

flash bank at91sam7 0 0 0 0 0


folgende Ausgabe bekomme ich:

> flash info 0
#0: at91sam7 at 0x00100000, size 0x00040000, buswidth 4, chipwidth 0
#0: 0x00000000 (0x40000 256kB) erase state unknown, protection state unknown

at91sam7 information: Chip is AT91SAM7S256
cidr: 0x270d0940, arch: 0x0070, eproc: ARM7TDMI, version:0x000, flashsize: 0x00040000
master clock(estimated): 19716kHz
pagesize: 256, lockbits: 16 0x0002, pages in lock region: 64
securitybit: 0, nvmbits: 0x0

was mich momentan noch wundert ist das "erase state unknown" und das
"protection state unknown".

außerdem funktionieren einige befehle einfach nicht - kann mir jemand
sagen warum?


> flash erase 0 0 15
Command erase not found
> flash write_binary 0 blink.elf
Command write_binary not found
> flash write 0 blink.elf
Command write not found

jemand eine idee?

Danke!
