Flash bin on at91sam7s64 using olimex arm usb

Postby RiccardoF » Thu May 11, 2017 8:22 am

Hi all!
I'm a newbie of this topic,
I have a bricked jlink clone wit an atmel at91sam7s64 where i have to flash the firmware.
I also have a olimex arm-usb-tiny to connect via jtag to the at91sam7s64.
I've already stetted up the environment, a pc wit linux mint, open ocd installed and a openocd cgf for the olimex.
thecfg is the following:
Code: Select all
interface ftdi
ftdi_device_desc "Olimex OpenOCD JTAG TINY"
ftdi_vid_pid 0x0403 0x6010

ftdi_layout_init 0x0808 0x0a1b
ftdi_layout_signal nSRST -oe 0x0200
ftdi_layout_signal nTRST -data 0x0100 -oe 0x0100
ftdi_layout_signal LED -data 0x0800
adapter_khz 18432

at the moment i can connect to the at91sam7s64 using
Code: Select all
sudo openocd -f /home/riccardo/Desktop/olimex-arm-usb-tiny-h.cfg -f/usr/local/share/openocd/scripts/target/at91sam7sx.cfg

and the response is:
Code: Select all

Info : Embedded ICE version 0
Error: unknown EmbeddedICE version (comms ctrl: 0x00000000)
Info : at91sam7s.cpu: hardware has 2 breakpoint/watchpoint units
