@cindex translation |
|
|
|
If you have a configuration file for another hardware debugger(Abatron, |
|
|
|
BDI2000, BDI3000, Lauterbach, Segger, MacRaigor, etc.), translating |
|
|
|
it into OpenOCD syntax is often quite straightforward. The most tricky |
|
|
|
part of creating a configuration script is oftentimes the reset init |
|
|
|
sequence where e.g. PLLs, DRAM and the like is set up. |
|
|
|
|
|
|
|
One trick that you can use when translating is to write small |
|
|
|
Tcl proc's to translate the syntax into OpenOCD syntax. This |
|
|
|
can avoid manual translation errors and make it easier to |
|
|
|
convert other scripts later on. |
|
|
|
|
|
|
|
Example of transforming quirky arguments to a simple search and |
|
|
|
replace job: |

|
