##
## Name: Makefile
## Created: July 2019
## Author(s): Philip Smart
## Description: App Makefile - Build an App for the ZPU Test Application (zputa)
## This makefile builds an app which is stored on an SD card and called by the ZPUTA
## test application. The app generally is for testing some component where the code is
## not built into ZPUTA or memory restrictions prohibit it being built in.
##
## Credits:
## Copyright: (c) 2019 Philip Smart <philip.smart@net2net.org>
##
## History: July 2019 - Initial Makefile created for template use.
##
## Notes: Optional component enables:
## USELOADB - The Byte write command is implemented in hw#sw so use it.
## USE_BOOT_ROM - The target is ROM so dont use initialised data.
## MINIMUM_FUNTIONALITY - Minimise functionality to limit code size.
## COREMARK_TEST - Add the CoreMark test suite.
## DHYRSTONE_TEST - Add the Dhrystone test suite.
## USE_SDCARD - Add the SDCard logic.

// Name: bwrite.c
// Created: July 2019
// Author(s): Philip Smart
// Description: Standalone App for the ZPU test application.
// This program implements a loadable appliation which can be loaded from SD card by
// the ZPUTA application. The idea is that commands or programs can be stored on the
// SD card and executed by ZPUTA just like an OS such as Linux. The primary purpose
// is to be able to minimise the size of ZPUTA for applications where minimal ram is
// available.
