How can I get additional mbed accounts

You can signup without access to an mbed platform. Then you can add platforms to your mbed Compiler by finding the appropriate platform on the platforms page and clicking "Add to mbed Compiler", this will allow you to compile for that platform.

We do have some sponsored units that we can send to the coolest/most interesting projects, but as always demand is far greater than supply.

I am getting an error "Fatal Application Error: Resource object failed to load" when I click on the "Compiler" link. A new window opens, but this error apprears and asks me to contact support.

I was using the compiler earlier in the day and it was working fine.

Hi Ali,

If you are having this problem, it was perhaps related to switching between beta mode and normal mode? May be your browser cache has somehow got mixed up. If you are still having problems, try clearing your browser cache and try again.

If you continue to have problems, give us an email at and we'll investigate further.

Thanks, Simon

I'm using an Acer Aspire One Net Book with Ubuntu 11.10. At the top of the mbed page, I see "Beta test the new". This sign is right on top of 2 headings. All I see to right is "book", which I believe is Cookbook. I see the rest of the headings OK to the right of "book".

I wonder if the Webmaster could slide this announcement down a bit? Maybe, on the next line starting with the word Handbook. Everything looks normal on my Desktop using the same OS.

Thanks, donde

Hello to all I have a big problem with my mbed. when I go on the mbed record(disk) and when I make proprieté he indicates me that 566ko sound occupied on the dique while he(it) not it in nothing on the record(disk). I cannot schedule(program) him(it) any more because when I put the binary file on the record(disk) and when I make a reset nothing takes place. Thank you for your coach I know more what to make, I have try to format but impossible.


28 Feb 2012

Hello, I makes for what you asked me and the program does not dash when I make a reset. on the other hand it there540 Kb of occupied on the mbed disk while that this just contains a page html. The problem comes from there probabely. I possess another mbed and on its record disk a file schedules(programs) of 23ko and the disk indeed indicates 23ko occupied. Thank you for giving me solution.
