Sample project to test CppUTest for Keil MDK-ARM toolchain and LPC1768 chip.
Requirements:
1. CYGWIN (rm.exe, mkdir.exe, make.exe)
2. Keil MDK-ARM
3. JLink Flash (for programming chip) or FlashMagic
4. serial connection to UART0 or UART1 interface
5. 12 or 24 MHz quartz. If else, need to be adjusted in
$(CPPUTEST_HOME)/platforms_startup/armcc/LPC1768/system_LPC17xx.c
(for _clock_init() function working correctly and to set up 100 MHz core
clock).
Please check system_LPC17xx.c for correct quartz selection in function
SystemInit(), and rebuild startup library for any change.
Default is 12 MHz quartz.
6. eclipse + gdb server from JLink + arm-none-eabi-gdb from GNU ARM Tools Embedded
For debug only.
First, you need to compile CppUTest and target startup library:
make -C ../../../platforms/armcc CPU=Cortex-M3 all
make -C ../../../platforms_startup/armcc/LPC1768 all
Second, you need to write tests. As example, I use
$(CPPUTEST_HOME)/examples/AllTests/CircularBufferTest.cpp.
Third, you need to make executable:
make all
Fourth, you need to program executable on target chip:
make prog
Project use semihosting, so you may use standard printf() or std::cout << "Hello!"
If problems with heap or low memory, adjust heap size in
$(CPPUTEST_HOME)/platforms_startup/armcc/LPC1768/startup_LPC17xx.asm
and rebuild startup library.
