Hello Rahul

First of all, thank you for your nice review from our FRDM-KL25Z board, it is nice to read that you appreciate our solution [View:/resized-image/__size/16x16/__key/commentfiles/f7d226abd59f475c9d224a79e3f0ec07-ed57753f-7145-44a1-b270-894686e36d5e/6138.contentimage_5F00_1.png:16:16]

I agree with you, MBed is a great evaluation tool, very confortable with its online format and ease of use with its existing libraries.

Unfortunately, MBed doesn't offer (yet) debug features so you will have to choose a classical IDE toolchain.

I recommend you Coocox, a free offline toolchain in the same community spirit than MBed or Aduino IDE.

Else you can choose either an ARM toolchain from Keil (MDK-ARM) or IAR (EWARM) or our home-made solution Codewarrior.

Concerning your issue to download Codewarrior 10.4, please try following links to start the download directly :

Special Edition means that the IDE toolchain will not time limited but code compiled limited (64KB Kinetis-L or E, 128KB Kinetis-K ...)

Online version means you will have to download a lighter installation package (650Mb) and you will have to download next the target package(s) (Kinetis, S12 ...)

Offline version means you will have to download a full installation package (1.2Gb) including all Freescale MCU targets

Special Edition: CodeWarrior for Microcontrollers 10.4 (Eclipse, Online)

Special Edition: CodeWarrior for Microcontrollers 10.4 (Eclipse, Offline)

About the headers, Freescale decided to remove them in order to reduce the board cost and make it accessible to the majority of the users.

Fortunately, Farnell/Element14 has launched a new bundle FRDM-KL25Z BASIC BUNDLEFRDM-KL25Z BASIC BUNDLE including all the headers and an USB cable for less than 1£ more compare to the FRDM-KL25Z

If you already received your FRDM-KL25Z and you want to acquire the headers, please find below their references and quantities:

With Gold contacts

1x Molex 15445812 = Samtec SSW-106-01-G-D

2x Molex 15445816 = Samtec SSW-108-01-G-D

1x Molex 15445120 = Samtec SSW-110-01-G-D

2x Molex 22284023 = Samtec TSW-102-07-G-S

With Tin contacts

1x Molex 15446812 = Samtec SSW-106-01-T-D

2x Molex 15446816 = Samtec SSW-108-01-T-D

Greetings from Pasig City, Philippines!

I have the FRDM-KL25Z board and have programmed it using GNU Tools for ARM Embedded in Linux CLI (command-line interface). I also program it using mbed.org online compiler. My latest project for this board is Speech Synthesis using SpeakJet, compiled using mbed.org online compiler.

Very nice board! I'm hoping to build a SpeakJet shield very soon.

Have a Nice Day!

Marcos

Greetings,

I agree, the headers should be included. I would rather pay a little more for the product with the header.

As it is, I had to drive 70+ miles to get them and, still had to cut them down to fit. I could have ordered them but...

I did not want to wait. I wanted to play now

I bought extra. Like Nico, just in case.

The problem I see is, if you are not careful at soldering you can destroy the board.

I like the option of using the IDE or MBED. if your prototyping or learning provides a lot of resources.

Rahul,

Good review.

Regards,

Steve

No I don't agree with you. As long as you where on point with the product you where ok. But then you talked about

(1) mini CDs, which I promptly disregarded; it's completely unnecessary.

Why did you even bother to load it and see what was on the CD??!!

(2) in order to download a trial version of the software, I had to create a full account with Freescale (giving out all sorts of details such as what the end product is), only to be presented with a message saying that my request will be processed, instead of a download link. Forget it!

To answer this problem takes a lot of restraint. I am a member of the TI E2E site. In the REAL WORLD that what they all do. If you want something for free you have to tell the man your details name, address, phone, etc. and they ask to tell them (a) your project, so they know what segment you fall in to; (b) your time frame; (c) how many of the thing are you likely to build...

I think maybe you should just grow up.

Nice review

I would agree with your comment about headers.

The very least is the ability to add them to the order.
