OVERVIEW

This nn article to hold notes on NXP/LPCXpresso programming tools and methods. Expet tools to include LPCXpresso Integrated Development Environment and command line based gcc, g++, as, ld, objcopy and related tools. Programming methods expected to include FTDI cable based programming employed with FlashMagic and lpc21isp. More to come going forward . . .

Powering down, grounding pins P0.1 and P0.3, then powering up, ungrounding both those pins and issuing part signature read command:

$ sudo lpc21isp -detectonly /dev/ttyUSB0 9600 12000
lpc21isp version 1.97
Synchronizing (ESC to abort). OK
Read bootcode version: 1

STM32F microcontroller and dev board

This section of LPCXpresso is not very related to LPCXpresso but here to describe tools for compiling for, programming and debugging ST32F type processors and dev boards.

- STEP - Searching for tool chain components which provide gcc-arm-none-eabi compiler and related linking and library tools:

$ dpkg -c /var/cache/apt/archives/gcc-arm-none-eabi_4.8.4-1+11-1_i386.deb | grep gcc$
-rwxr-xr-x root/root    711032 2015-03-14 10:50 ./usr/bin/arm-none-eabi-gcc
hrwxr-xr-x root/root         0 2015-03-14 10:50 ./usr/bin/arm-none-eabi-gcc-4.8 link to ./usr/bin/arm-none-eabi-gcc

- STEP - building Texane's stlink programming utility for ST32F and related target processors:

Looks like there are a couple of extra steps to take to build developer or dev team Texane's stlink project. These steps include installing `cmake`, and then on Debian and Ubuntu systems invoking stlink's makefile as follows:

$ make clean && make release
