Freescale Freedom FRDM-K64F Development Platform

They actually contain more - in addition to the K64F - the kits contain a controller board which may be used in your projects.

You r Lucky Guys !! best part is qsg for ibm cloud integration I am hoping to learn a lot from these reviews.

Awesome, thank you for the update!  Do these have any significant difference between these and the original ones?

Thank you to everyone for your patience, there has been a severe shortage of FRDM-K64F's due to high demand.  In order to ameliorate the issue, we have been talking to IBM and ARM who have produced this FRDM-K64F based kit -

The first five of these have arrived and will be dispersed to the testers in whose countries the kits have been approved for use; we will need to check this before shipment, so I estimate the first shipments will be sent next week.

Thanks again.

Has anyone received their RoadTest package with this board yet?

Any Updates?

Ahh, I was hoping there was a delay somewhere because I was beginning to be worried the postal service would be my demise in further RoadTests.

Thank you for the update!

Christian,

     Thanks for your update! Please keep us informed...

We are experiencing shipping delays due to the recent holidays in the United States; thank you for your patience.

I have not received mine either.  My mailbox has been full of disappointment everyday I wait on the unit.

and you would be correct, strings in C are zero terminated automatically, if you had used a char[] instead then that would be a different story

Nada (out of stock!)

Has anyone received the unit yet?

I'm waiting impatiently to get started and review it, but I haven't received it yet.

Hello Clem Martins,

If I remember correctly (but it could be different with Codewarrior) that when you define something as a string it is automatically appended with a null terminator. But even if I am wrong the whole I2C communication happens before this point. therefore there should be some reply from the device before even reaching the infinite loop.

Thank you for the help though

@Kas Lewis I did notice that your character string does not have a "/0" or null value, yet you test for this value in your while loop...

1. char string[] = "My name is Bob C. Marley \r\n\r\n";
2. while(1) {    
3.     for (i = 0; string[i] != '\0'; i++){ 
4.     Uart_SendChar(string[i]); 
5.     }

Worst thing about Freescale is there LACK of support. I have been trying to get the I2C working on my KEA-64 board for THREE WEEKS and all they can do is send me more demo code that is bloated and overly complicated.

As you can see I have the I2C module mostly working, but nothing I try, including following what here myriad of examples shows, to do to get the clock KEA-64 to provide a clock for the device to send back data seems to work. I have tried this with TWO I2C devices and both give the exact same result so it must be the KEA-64. Their "help forums" are hardly any help so I am hoping someone here may have some REAL answers. I am including my code below, and hopefully someone can point to the error I have made in MY code.

Yes, yes Thankyou.. I was looking over some other roadtest and there I saw the t&c(as you already mentioned) and was going to edit the last comment but you already replied on that. Thank you anyways!!

Hi mudz, it starts from the moment you receive the kit.

Testers are required to produce a full, comprehensive and well thought out review within 2 months of receipt of the product

Frederick

Nope.. Still waiting.

Also, does this 2 months period (to submit review) has already been started or it will start when we recieve kit? I think it has already been started.

See anything yet @mudz? Not here!
