Move mbed to my own hardware, possible?

After a lot of searching, I can not get a definitive answer on my thought...

What steps do I've to take to connect to the online mbed environment if I buy a single chip LPC1768FBD100 (e.g. from digikey) and built my own PCB board (including USB) for it?

Is there a sort of bootloader that I've to program in the LPC first?

It is absolutely possibly to use programs developed for your mbed device on a single chip on a custom PCB.

You may find this notebook page useful http://mbed.org/users/chris/notebook/prototype-to-hardware/

The interface chip itself is not currently available apart from as part of an LPC1768 or LPC11U24, however there will soon be an announcement that will interest people that want to use the interface chip in their own designs.

Thanks for your reply. But this is not what I mend. My mbed now mounts as a mass storage device where I can drop the image in. Is there a place where I can get that IC that does the trick as a "USB MSD programmer" to flash it inside my new LPC chip? So I can get it working exactly like an mbed?

I don't think so yet but watch this space as I'm working on this exact problem!

Willem, the interface chip is not currently available on its own. However in the next few weeks there will be an important announcement that you will find very interesting.

If you use the LPC11U24, Then you can envoke the USB Bootloader, Which you save the bin file to (as pen - drive)

Search for some of my posts !!!

There is no simple way around programming LPC1768, Other than flash magik

But somewhere, I have seen someones program, Which takes a re - named bin file, converts it to a hex file, Then you could push that file into LPC1768.

Might of been coded for it??

Hope that was helpfull.

Thank you so much for the reply's.

I can't get away with the LPC11u24 since I need Ethernet.

I was having doubt choosing for a Raspberry Pi or Mbed. In my case the mbed only wins the game if i build more than 50 units. But on of my headlights are the ease of (re) programming of the product. This will allow non-elektro-technical users to change the source code more easily.

Looks like the mbed will not do the job for my project since a seperate mbed module will be more expensive than the Rpi
