Hi there.
I want to program my str710 ARM processor in flash.
I have read a bit on how James P. Lynch have used make to program a AT91SAM7S.
My problem is that exept from within eclipse I don’t know how to communicate whit openocd, and I have not enough understanding yet to know what is going on when he uses the makefile.
No offend, He’s tutorial is great!!! it is my knowledge that is not there yet.
How would we normally attatch to openocd. how do I establish an telnet interface with it?

I am trying to use a target_script with the following commands:
erase sector 0 - 2 of bank 0
flash erase 0 0 2
program test.bin to bank 0, offset 0
flash write 0 test.bin 0x0
It does not seams to work, the old program is still in the flash.
My program is based on STR7Test from the “YAGARTO” sites.
I have commented out the lines in the startupfile that tells the cpu to map ram down to the bootsector
/////////////////////////////////////
ldr r0, =PRCCU_BASE
ldr r1, =0x01C2
str r1, [r0, #PCU_BOOTCR]
/////////////////////////////////////
I don’t know if that is enough and since it is based on STR7Test, there might be more things I have overlooked.
I am using a hitex str7 evaluation board.
As you might guess I am a newbie

Hi Raymond.
I’m using the STR7 with the STR710-eval board from ST and an Amontec USB JTag Key. Here is my config file:

I don’t know your eval board nor with what JTAG probe you flash the device. I think that you first should try to flash part of your STR7 flash memory with some binary data, and then read it back. Once this is working, you can focus on demo code to run, and how to run it (the STR7 has pins that tells it to boot from internal RAM or FLASH, or external memory)

I finaly did it. 
I have programmed my STR7 in FLASH.
Now I only have to understand what happend.
For a newbie like me (I have been programmed come c, c++ and a littlebit assambler for atmel 8 bit avr processors before), the hardest thing to understand the makefile with all the flags.
By the way. I was clicking on the link that “Potedbas8” was posted.
It seems to somewhat contain spyware.
