[FreeRTOS Home] [Live FreeRTOS Forum] [FAQ] [Archive Top] [May 2009 Threads] OpenOCD and AT91SAM7 flash programmingPosted by Adam Turowski on May 17, 2009 I am trying to get OpenOCD working and I've managed to connect it with GDB and AT91SAM7X256. Debugging seems to work fine. Unfortunately I've tried to use OpenOCD to program MCU internal flash, but without success. Can you please provide me example of OpenOCD/GDB configuration file/commands which allows you to program internal flash?
Thanks, Adam
RE: OpenOCD and AT91SAM7 flash programmingPosted by Richard on May 17, 2009 There are some example scripts in the FreeRTOS download - with documentation provided on the FreeRTOS.org WEB site. However the version in the download is rather old and the commands are different if you are using a newer version of OpenOCD.
You can also use the Atmel provided SAM-BA program to program the flash rather than using OpenOCD for this.
Regards.
RE: OpenOCD and AT91SAM7 flash programmingPosted by Joel cote on June 30, 2009 I already use SAM-BA to program the flash and it's work, but I need to program the flash with the JTAGkey_tiny Amontec. I want a know if someone have some cfg file with the new command who work with open ocd 0.1.0. when I try to program the flash with open ocd with the external tool of eclipse i have this error :
OLD SYNTAX: DEPRECATED - translating to new syntax jtag newtap CHIP TAP -irlen 4 -ircapture 0x1 -irvalue 0xf Example: STM32 has 2 taps, the cortexM3(len4) + boundryscan(len5) jtag newtap stm32 cortexm3 ....., thus creating the tap: "stm32.cortexm3" jtag newtap stm32 boundry ....., and the tap: "stm32.boundery" And then refer to the taps by the dotted name. NEW COMMAND: Runtime error, file "C:\0Data\SAM7_flash.cfg", line 23: bad option "arm7tdmi": must be one of count, create, current, names, number, or types
Can someone help me?, I really don't know what to do.
thank
Joël

RE: OpenOCD and AT91SAM7 flash programmingPosted by Stefano Oliveri on July 3, 2009 Hi all,
I received a working configuration file for AT91SAM7x / OpenOCD 0.1.0 / Amontec JTAGkey-Tiny. It uses only one big .cfg file. I can't test it because I have not board based on that MCU! But people are reporting that this file work fine, and... you can quickly try it!
Regards, Stefano
