Creating a new Algorithm
|
||
------------------------
|
||
|
||
Flash programming algorithms are defined with functions to erase and program
|
||
the Flash device. Special compiler and linker settings are required. Follow
|
||
these steps to create and configure a new Flash programming algorithm:
|
||
- From the toolbar, use the drop-down Select Target to define the processor
|
||
architecture. Cortex-M fits for all Arm Cortex-M0/M0+/M3/M4/M7 devices.
|
||
The configuration assumes a little-endian microcontroller. In case of a
|
||
big-endian microcontroller, select the correct processor core with
|
||
Project - Options for Target - Device.
|
||
- Open the dialog Project - Options for Target - Output and change the content
|
||
of the field Name of Executable to represent the device, for example
|
||
MyDevice.
|
||
- Adapt the programming algorithms in the file FlashPrg.c
|
||
- Adapt the device parameters in the file FlashDev.c
|
||
- Use Project - Build Target to generate the new Flash programming algorithm.
|
||
The output file (for example MyDevice.FLM) has to be added to the DFP.
|
||
|
||
Note
|
||
----
|
||
- Creating a Flash programming algorithm with MDK-Lite is not supported.
|
||
- Flash programming algorithms use Read-Only Position Independent and
|
||
Read-Write Position Independent program code. These options are set in the
|
||
dialogs Project - Options for Target - C/C++ and
|
||
Project - Options for Target - Asm.
|
||
- The dialog Project - Options for Target - Linker defines the linker scatter
|
||
file Target.lin. The error L6305 is disabled with –diag_suppress L6305.
