This directory holds the *.emp files generated by the EM Micro tools (e.g. EM9304 Configuration Editor) or EM Micro developers (code patches).
|
||
|
|
|
||
|
|
All *.emp files contained in this directory will result in the generation of a patch or patches to be
|
||
|
|
applied to the EM9304.
|
||
|
|
|
||
|
|
The script emp2include.py has the following usage:
|
||
|
|
|
||
|
|
$ ./emp2include.py --help
|
||
|
|
usage: emp2include.py [-h] [-o MEMORY]
|
||
|
|
|
||
|
|
Convert multiple EM9304 *.emp files to the em9304_patches.* files.
|
||
|
|
|
||
|
|
optional arguments:
|
||
|
|
-h, --help show this help message and exit
|
||
|
|
-o MEMORY Destination memory (IRAM or OTP)
|
||
|
|
|
||
|
|
Patches can be applied temporarily to IRAM and then permanently applied to OTP (one-time programable) memory
|
||
|
|
as needed. The default is IRAM.
|
||
|
|
|
||
|
|
