OVERVIEW
This nn article to hold notes on LPCXpresso Integrated Development Environment and NXP microcontroller programming methods. Author Ted expects the IDE to include or call on tools such as gcc, g++, as, ld, objcopy and related others. Programming methods expected to include FTDI cable based programming employed with FlashMagic and lpc21isp.
As of 2018 Q2 article contributor Ted using LPCXpresso v8.2.2 [Build 650] [2016-09-09].
In addition to some initial notes on NXP parts, also this article contains some notes and references on STMicro's STM32F100 family micro-controllers. This controller is different enough that it deserves an STM32F100 article of its own . . .

^ LPCXpresso 1114 board and FreeRTOS
In order to get started with the FreeRTOS port demo project to the LPC1114 board, a batch file (or shell script) need be run to create a particular directory structure and copy files into some project-expected places. There is mention on the ported NXP project page on FreeRTOS site that LPCXpresso IDE can provide makefile based projects, and "managed make" projects. The managed make projects require all sources on which a given project depends to be located within given project's top level directory.
There is mention of a batch file which on our Linux box appears to be ~/Downloads/freertos/FreeRTOSv10.0.1/FreeRTOS/Demo/CORTEX_M0_LPC1114_LPCXpresso/RTOSDemo/CreateProjectDirectoryStructure.bat.

^ Copying FreeRTOS Demo Project To Begin New Project
- 2018-06-13 TUE -
Today's goal is to copy the FreeRTOS demo which runs on an LPCXpresso development board, and to bring this copy of the project up as a second or additional project in LPC IDE's workspace. From here then next step is to add one-way then bidirectional UART communications to the project.
A separate second goal is to craft a GNU makefile to build this same demo project.
Looking at project properties by means of right clicking the top level folder in LPCXpresso's project navigation pane, the project's location on the file system is:
localhost:/home/user/Downloads/freertos/FreeRTOSv10.0.1/FreeRTOS/Demo/CORTEX_M0_LPC1114_LPCXpresso/RTOSDemo
The readily visible, top level contents of this directory are:
~/Downloads/freertos/FreeRTOSv10.0.1/FreeRTOS/Demo/CORTEX_M0_LPC1114_LPCXpresso/RTOSDemo$ ls CreateProjectDirectoryStructure.bat Source z--002--create-project-structure.txt Debug create-project-directory-structure.sh z--create-project-structure.txt
There are a couple of hidden project files here, created and or used by LPCXpresso:
$ ls -a . .cproject .settings Debug create-project-directory-structure.sh z--create-project-structure.txt .. .project CreateProjectDirectoryStructure.bat Source z--002--create-project-structure.txt
Note: in the LPCXpresso managed product directory there are hidden files named .cproject and .project . . .
Both files .cproject and .project are XML files. The file .cproject is longer among these two files and includes details of the compiler used in a given project, plus options passed to this compiler, plus at least one project include path. The file named .project contains in the first few lines a line expressing the project name as LPCXpresso IDE knows it. This project name must be unique within the projects imported to a given LPCXpresso workspace. This workspace on Unix and Linux-like systems defaults to the directory ${HOME}/LPCXpresso.
The name of the project we're attempting to copy and start as a new and editable project is 'RTOSDemo', a patterm which appears several times in file .cproject:
Figure x -
$ grep -n RTOSDemo ../.cproject
23: <builder arguments="-r" buildPath="${workspace_loc:/RTOSDemo/Debug}" command="make" id="com.crt.advproject.builder.exe.debug.1260101970" keepEnvironmentInBuildfile="true" managedBuildOn="true" name="Gnu Make Builder" superClass="com.crt.advproject.builder.exe.debug"/>
40: <listOptionValue builtIn="false" value=""${workspace_loc:/FreeRTOS/Demo/CORTEX_M0_LPC1114_LPCXpresso/RTOSDemo/Source}""/>
61: <option id="com.crt.advproject.link.script.1758870530" name="Linker script" superClass="com.crt.advproject.link.script" value=""RTOSDemo_Debug.ld"" valueType="string"/>
118: <builder buildPath="${workspace_loc:/RTOSDemo/Release}" id="com.crt.advproject.builder.exe.release.1281961847" keepEnvironmentInBuildfile="false" managedBuildOn="true" name="Gnu Make Builder" superClass="com.crt.advproject.builder.exe.release"/>
149: <option id="com.crt.advproject.link.script.1856833348" name="Linker script" superClass="com.crt.advproject.link.script" value=""RTOSDemo_Release.ld"" valueType="string"/>
182: <project id="RTOSDemo.com.crt.advproject.projecttype.exe.777175218" name="Executable" projectType="com.crt.advproject.projecttype.exe"/>
343: <resource resourceType="PROJECT" workspacePath="/RTOSDemo"/>
346: <resource resourceType="PROJECT" workspacePath="/RTOSDemo"/>
$
Unfortunately the LPC1114 FreeRTOS demo project name is used in two or three different ways in the file named .cproject. Most of the time it is used as the project's name, but a couple of times this text pattern or name appears in the filenames of linker scripts. In another instance it's part of a host system directory path to the project. The places where pattern 'RTOSDemo' most closely relates to LPCXpresso project are where it appears on lines which refer to ${workspace_loc}. Given this it looks like we want to change the project name RTOSDemo to a new project name on lines 23, 118, 343 and 346, where this name stands for a project name, rather than part of a path or part of a linker script filename.
LPCXpresso file .project contains two references to the pattern RTOSDemo:
$ grep -n RTOSDemo ../.project
3: <name>RTOSDemo</name>
35: <value>${workspace_loc:/RTOSDemo/Debug}</value>
^ edit point - create directory structure script
A file worth noting here is a shell script which Ted adapted from a DOS batch file which ships with the RTOS demo. The original batch file and the adapted shell script create a directory structure and copy FreeRTOS header and source files to these directories, placing all sources in the local copy of the project. While the following script does the copying job for a project in one particular path relative to the FreeRTOS download path, Ted amended this script further to put relative source path elements into variables. This makes the script more adjustable to be executed in different locations. As of 2018-07-09 Monday that improved script not posted here on this wiki article yet . . .

The above figure is a verbose way of showing approximate size of combined build time files such as object files. But this snippet also shows project directories and directory structure. This structure is largely created by the DOS batch file on Windows hosts, and in this case created by the shell script which mimics those same steps. Manually copying this project with these directories then, there should be no need to run the batch file . . .

^ Makefile Clues - Deriving A Working Makefile From LPCXpresso Projects
It's really frustrating to understand how LPCXpresso builds software projects. LPCXpresso automatically generates a makefile, and child makefiles in additional subdirectories of its imported and created projects. For example, LPCXpresso creates child makefiles in each directory which contains project sources. These child makefiles are read by the `make` utility recursively, as LPCXpresso calls its choice of `make` with the -r option.
Some options which would normally be encapsulated in the makefile are held in some other settings space or stored files of LPCXpresso and passed to the call to make at build time. This makes it harder to see all the details of the project build recipe, because they're spread out over multiple files, and some options do not even appear to be stored in files.
According to an NXP Community thread, LPCXpresso supports command line based project builds . . .
Despite possible command line based builds we have not yet learned how to set this up, and are presently stuck with LPCXpresso's default build process. This build process includes a utility or option called CDT builder, which appears next to a checkbox in one of the dialog boxes under a given project's properties:
Properties --> Builders
A couple of supporting lpcxpresso project makefiles include makefile.init and subdir.mk. These files contain respectively:

^ Build Issues While Developing Makefile
2018-06-15 - One of the first issues we encounter while creating a makefile for the FreeRTOS demo targeting LPC1114 processor is gcc's complaint of not finding the specifications file named redlib.specs. Gcc.gnu.org talks about specs files at this page:

We've solved a couple of simple vpath and -I include path problems, but are running into something maybe more subtle or obscure. Gcc is getting an assembly file and does not know how to compile this assembly:

Ok a lot going on here. Also noting that when gcc given -v option for more verbose output, there are some non-existent paths which gcc mentions, which are expressed in the redlib.specs file. These don't look like a source of problems. Also notice there are two identical but differently named instances of the cross-assembler gnu-none-eabi-as:

^ edit point - gcc 6.3 or newer may be needed
An obscure error appears now with our call to the GNU assembler, which gives a complaint about width suffixes in one of FreeRTOS demo assembly files. Per https://sourceforge.net/p/freertos/discussion/382005/thread/8041642a/ we may need a newer version of gcc, e.g. 6.3 over 4.x in order to get past the error:

Link time issues can come up before all sources have been built. The linker `ld` or similar needs to know where project-related libraries are on the local file system. Here in the next figure / build excerpt are messages showing the linker not finding certain library function definitions:

^ edit point - finding and pointing make to .a library files
On Thursday, yesterday, we found a makefile created by LPCXpresso or one of its called tools, in the Debug directory of our RTOSDemo project instance. Working now with a copy of that makefile in a project we did not import, nor unzip from a zip archive, but started out as a general C/C++ project. TO DO: Contributor Ted notes here that we must retrace those project creation steps so we know thoroughly how to get a project off the ground in the LPCXpresso IDE.
There are different types of library files in C and C++ projects, library files which can be linked in to a binary at compile time or loaded at run time. On the Linux and GCC side it may be necessary to point `make` to dot a archive type library files, by using the -L option . . .

So one thing we see is that symbol ResetISR appears in linker files of type .ld, in .map files and in .c files. Symbol ResetISR does not appear in any header files of this project. Where in our rtos-demo-with-mods project makefile do we touch or change references to any .map files? . . .

46 * block for 200 milliseconds, before sending the value 100 to the queue that
47 * was created within main_blinky(). Once the value is sent, the task loops
48 * back around to block for another 200 milliseconds.
This time period is puond defined on about line 79 in main-blinky.c:
#define mainQUEUE_SEND_FREQUENCY_MS ( 200 / portTICK_PERIOD_MS )
