Btw ... have never tried Energia , but have just build it from github (Linux Mint 17 / Ubuntu 14.04).
A 1.2GB "clone"
, but very fast build of whatever has to been build , certainly not the compilers (only took a few minutes)
It took me a few minutes to find the "executables" , that's placed in : Energia/build/linux/work
I didn't want to use "ant run" every time i wanted to start energia.

He..He - Syscall routines (newlib) in the startup ..... Nasty .....

bss/ebss errors "smells of" missing linker file definitions
Maybe try one of the energia linkerfiles (they seem to have bss/ebss)
https://github.com/energia/Energia/tree/master/hardware/lm4f/cores/lm4f
https://github.com/energia/Energia/blob/master/hardware/lm4f/cores/lm4f/lm4fcpp_blizzard.ld
https://github.com/energia/Energia/blob/master/hardware/lm4f/cores/lm4f/lm4fcpp_snowflake.ld
Ohh and i'd recommend to drop the Codesourcery compiler , and get the arm-gcc compiler from launchpad.

Thanx spirils , for the ansvers

You mention an IRC channel in the other post , could you come up with some more info ?
/Bingo

Thanx
Just found your nice explanation here
Is the TARGET_IS just used for the ROM functions ?
I have also used
MCU = TM4C1294NCPDT
And hope that's correct

Got my two EK-TM4C1294XL , with XM4C129 chips
Decided to skip the "Unknown connect" to the demosite , and build + load "blinky" - D1 is blinking green
I'm using GCC , and the nice template from here , and the lm4flash (as root)
https://github.com/uctools/tiva-templateConnect the debugport with the USB cable and fire away:
build $ sudo /home/bingo/bin/lm4flash main.bin
Found ICDI device with serial: 0F0006C6
ICDI version: 12245
I wonder what the makefile entry - really should be (seems like the new tivaware rel notes says they abandoned the BLIZZARD stuff)CFLAGS += -DTARGET_IS_BLIZZARD_RA1

Just saw this free book from Geoffrey Brown , a guy i have had some dialouge with, after i did the Versaloon port to the STM32-VL-Discovery board.
Looks like he did a nice work here

Hmmm ....
My "crystalball" is out of order right now.
So i cant look at your screen to see error messages etc ...
So ... Sorry i cant help
/Bingo

I'm to lazy to look it up , but i'm quite sure there is some kind of "register mask" that can be set , so that any writes will only affect the low half of the port

EA has released the source for theit demo (mbed code)
http://www.embeddedartists.com/sites/default/files/support/xpr/LPC812_max/LPC812MAXdemoTest_revPA1.zip
I just "tried" to port it to CMSIS , it is an ugly hack and the formatting is terrible.
I have no idea if i got the I2C right , but it responds to the button.
Edit: I just threw the source through indent , so the formatting is a bit nicer.

If anyone else got a 1$ LPC812 Max board.
http://www.embeddedartists.com/products/lpcxpresso/lpc812_max.php
And want to do a blinky with arm-gcc , i just completed one with help from the below repos.
https://github.com/sebseb7/lpc8xx
1: Get the base repos
git clone https://github.com/sebseb7/lpc8xx
2: Extract the attached sources into the newly cloned lpc8xx dir.
3: make
4: insert the lpc812 MAX Board into an USB slot on the pc (it'll open a new file-explorer window , like an usb-disk)
, pull the blinky.bin onto the "disk"
5: Press the Reset Key on the board , and your program is running.
I use linux , and arm-gcc from here https://launchpad.net/gcc-arm-embedded

Strange ...
And you made sure that the includes i mentioned was included before the "Cpu include"
/Bingo

Did you try to include stdint.h
I don't use CCS , but would expect it also have a stdint.h
The net suggests to include stdbool.h , for the bool definition
Both ought to be system defs meaning : #include <stdint.h> , and not #include "stdint.h"

Thanx BravoV (& TI)
Also got 2 Tiva's ....
Dropped LM4F-Launchpads , as i have 4 , and the silicon is prob still buggy
/Bingo
Edit:
I'm linux based ,and Firefox wont download the TI SW ...
I had to use Chromium ...
A Snip from TI's forum
Update 03-Sept-2013:
We discovered this week that the current release of Firefox (v23.0.1) contains some type of script that interferes with software downloads from TI.com. Of course, this impacts a good deal of Stellaris and Tiva software. We have tested downloads with both IExplorer and Chrome, and both of these browsers have no problems with downloads at all.
If you are having problems downloading TI software, please try the download using either Chrome or Internet Explorer.

Just saw this

Rather cool

Oops ... Double post .... Maybe a MOD can remove one of them

Buying anything like that in single quantities is annoyingly difficult here in Denmark as well. As a consequence I always wait until I need
alot of things and place orders at Mouser. I've also managed to order stuff together with a couple of collegues.
Mouser has free shipping for purchases over 100USD, and besides VAT (25% in Denmark), I have never paid any extra custom fees. But then again, in Denmark there are no custom duties to be paid for electronics components.
So, if you are interested in buying 39, I think the price would be around 100USD making the shipping from Mouser free.
Thanx for the tip.
I seem to remember they were a lot cheaper @Arrow , and wa shoping we could hit the 100 pcs price.
But else i'll have a loon at Mousers shipping again.
Thanx for the tip

I would love to get my hands on a few of those DIP's ....
But Shipping + customs Fee's are killing me (will be around 100$) ....
Wonder if we could make a "Group buy" us poor sods in EU ...
I'd be in for 39+ ... Afaik they come in tubes with 13 ...

Ok,.. I just went ahead and created an example. See below.
stellarisLaunchpad_floatingPoint_sprintf_usage.JPG
Hmmm
You got another board than i have ...
My board wouldn't print those floats if all there is in main is : return(0)
Ohh and return(0) in main() on an OS-less mcu wouldn't be my "first choice" unless i loved "HaraKiri" or some other nastyness

Nice
Is this code usable for the other stellaris arm's also, or is it 1294' specific ?
