OpenOCD flash programming SAM7-P256 AT91S

Development Boards MicroMod
1

Hello. I have recently received an Olimex SAM7-P256 development board with an Atmel AT91SAM7S256. I have also received an OCD-USB-TINY which I would like to use with the YAGARTO (or similar) toolchain.I am powering the board from an external 5V DC supply. (WinXPSp2, I gave up on using my linux box a week ago)

I have managed to connect to the OCD-USB-TINY using openocd and a custom config file, but have been unable to program or even attempt to program by all accounts.

Any comments are appreciated.

Here’s the result, i see red flashing on the device, but the embeddedice_read_reg_w_check just runs forever.

Try to lower the JTAG speed in openocd_at91sam7s_flash_ftdi.cfg

jtag_speed 10 ( higher values are slower)

Regards,

Magnus

Increasing the jtag_speed seems to have no effect. Also I misspoke earlier I have a ARM-USB-TINY not a OCD-USB-TINY.

I wonder why nothing is happening?

It was the BDS jumper on the dev board. I thought I tried that, but this time it worked.

Hi all,

I have the same problem on Windows Vista. I’m using openOCD 204, ARM-USB-TINY. Here’s what I get:

Error: ft2232.c:1341 ft2232_init_ftd2xx(): unable to open ftdi device: 2

Error: ft2232.c:1356 ft2232_init_ftd2xx(): ListDevices: 2

Error: ft2232.c:1358 ft2232_init_ftd2xx(): 0: Olimex OpenOCD JTAG TINY B

Error: ft2232.c:1358 ft2232_init_ftd2xx(): 1: Xš:

This is the part of the config that matters:

#interface

interface ft2232

ft2232_device_desc “Olimex OpenOCD JTAG TINY A”

ft2232_layout “olimex-jtag”

ft2232_vid_pid 0x15BA 0x0004

jtag_speed 20

What is the solution?

Thanks,

Gil

jtag_speed 20

reset_config trst_and_srst separate

jtag_device 4 0x1 0xf 0xe

jtag_nsrst_delay 333

jtag_ntrst_delay 333

daemon_startup reset
