|
// Description: Standalone App for the zOS/ZPU test application.
|
|
// This program implements a loadable appliation which can be loaded from SD card by
|
|
// the zOS/ZPUTA application. The idea is that commands or programs can be stored on the
|
|
// SD card and executed by zOS/ZPUTA just like an OS such as Linux. The primary purpose
|
|
// is to be able to minimise the size of zOS/ZPUTA for applications where minimal ram is
|
|
// available.
|

|
|
// History: July 2019 - Initial framework creation.
|
|
// April 2020 - Updates to function with the K64F processor and zOS.
|
|

|
// Notes: See Makefile to enable/disable conditional components
