The tbasic, kilo, and ed apps unconditionally overrode HEAPADDR/HEAPSIZE with ZPU BRAM addresses (0x1FFF5000+0x33000=0x20028000) that exceed the K64F app CODE region. Wrapped overrides in ifeq ($(__ZPU__),1) so K64F builds use the default heap/stack calculated by build.sh. Also disabled mbasic K64F build (heap overrides + code size exceed CODE region) — mbasic was already disabled for ZPU. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

## Name: Makefile
|
|
## Created: July 2019
|
|
## Author(s): Philip Smart
|
|
## Description: App Makefile - Build an App for the ZPU Test Application (zputa) or the zOS
|
|
## operating system.
|
|
## This makefile builds an app which is stored on an SD card and called by ZPUTA/zOS
|
|
## The app is for testing some component where the code is not built into ZPUTA or
|
|
## a user application for zOS.

|
|
## History: July 2019 - Initial Makefile created for template use.
|
|
## April 2020 - Added K64F as an additional target and resplit ZPUTA into zOS.
|
|
## 23/4/2020 - Updated to merge mini basic, ed and command processor.
|
|
##
|
|
## 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.
