Added scu driver file scu.c. Modified Makefile/Makefile.include to generate .map file and use -O2 as optimization. Modified hackrf-jellybean miniblink.c to enable 1V8 and blink LED1,2&3 with configuration of PinMux and GPIO. --- lib/lpc43xx/Makefile | 5 +++-- lib/lpc43xx/scu.c | 30 ++++++++++++++++++++++++++++++ 2 files changed, 33 insertions(+), 2 deletions(-) create mode 100644 lib/lpc43xx/scu.c (limited to 'lib/lpc43xx') diff --git a/lib/lpc43xx/Makefile b/lib/lpc43xx/Makefile index 4b8eae4..dd6f1cd 100644 --- a/lib/lpc43xx/Makefile +++ b/lib/lpc43xx/Makefile @@ -3,6 +3,7 @@ ## ## Copyright (C) 2009 Uwe Hermann ## Copyright (C) 2012 Michael Ossmann +## Copyright (C) 2012 Benjamin Vernoux ## ## This library is free software: you can redistribute it and/or modify ## it under the terms of the GNU Lesser General Public License as published by @@ -24,13 +25,13 @@ PREFIX ?= arm-none-eabi #PREFIX ?= arm-elf CC = $(PREFIX)-gcc AR = $(PREFIX)-ar -CFLAGS = -O0 -g -Wall -Wextra -I../../include -fno-common \ +CFLAGS = -O2 -g -Wall -Wextra -I../../include -fno-common \ -mcpu=cortex-m4 -mthumb -Wstrict-prototypes \ -ffunction-sections -fdata-sections -MD \ -mfloat-abi=hard -mfpu=fpv4-sp-d16 # ARFLAGS = rcsv ARFLAGS = rcs -OBJS = gpio.o vector.o +OBJS = gpio.o vector.o scu.o # VPATH += ../usb diff --git a/lib/lpc43xx/scu.c b/lib/lpc43xx/scu.c new file mode 100644 index 0000000..bc495cd --- /dev/null +++ b/lib/lpc43xx/scu.c @@ -0,0 +1,30 @@ +/* + * This file is part of the libopencm3 project. + * + * Copyright (C) 2012 Benjamin Vernoux + * + * This library is free software: you can redistribute it and/or modify + * it under the terms of the GNU Lesser General Public License as published by + * the Free Software Foundation, either version 3 of the License, or + * (at your option) any later version. + * + * This library is distributed in the hope that it will be useful, + * but WITHOUT ANY WARRANTY; without even the implied warranty of + * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
