OpenOCD scripts

OpenFacts, the Open Source Knowledge Database

This page will collect some script examples for different CPUs.

The configuration script can be divided in the following section:

• deamon configuration
• interface
• jtag scan chain
• target configuration
• flash configuration

Detailed information about each section can be found at OpenOCD configuration

Please indent every line of your sample script with a single space so OpenOCD will format it as script and wont try to interpret # chars and alike. Take a look at the STR710 example how to use it.

The following two scripts was used with an wiggler PP and and a TI OMAP5912 dual core processor (http://www.ti.com) on an OMAP5912 OSK board (http://www.spectrumdigital.com).
