# Makefile for the OpenGD77 MD-UV380 / Retevis RT-3S firmware (MDUV380_FW config).
|
|
#
|
|
# This reproduces the STM32CubeIDE "MDUV380_FW" build configuration (extracted
|
|
# from MDUV380_firmware/.cproject) as a plain Makefile so the firmware can be
|
|
# built headlessly.
|
|
#
|
|
# It is intended to be invoked with the current working directory set to a
|
|
# build directory that is a *direct child* of MDUV380_firmware/ (so that "../"
|
|
# resolves to the project root), exactly like CubeIDE's generated makefiles.
|
|
# The .incbin path inside codec_bin.S ("../application/source/linkerdata/...")
|
|
# relies on this layout.
