|
* Purpose: This script provides a description of the Cmod S6 Zip CPU
|
| 8 |
|
|
* build for the purposes of where to place memory when linking.
|

|

|
|
* This script is different from the cmod.ld script in that this script
|
| 11 |
|
|
* places specific pieces of code into RAM rather than FLASH. This is to
|
| 12 |
|
|
* speed up those particular pieces of code. This script also depends
|
| 13 |
|
|
* upon a bootloader to load the RAM sections into RAM with their initial
|
| 14 |
|
|
* values.
