Is this older or newer than the "Ver2.01" I had preinstalled on mine?

I have a unit with firmware version 1.1, but people here seem to be talking about a version 2.01 - where would I get his upgrade? I havent found any links on the seed website or this forum for it. also, is there a changelog somewhere?

I tried compiling the codes provided above using IAR 5.40, it requested the workspace to be updated since it was created from an old version of EWARM. After which I was not able to continue with the compilation with the ff. errors:

Error[Li005]: no definition for "__program_start" [referenced from C:\DS0201_OpenSource\DS0201_DFU\project\EWARM\Debug_FLASH\Obj\
Error while running Linker

Comparing the provided sourcecode above with the codes provided by bure from the chinese forums, mostly the changes were the logo and the comments (which are very good). I would like to know if the updated source code will be released, since its tagged as an opensource device. Hopefully it will be compatible with the latest IAR IDE (v5.40)

I noticed that the latest f/w shows v1.1 in the logo, I believed the hardware that seeedstudio will release is a 1.3a and not a 1.1.
I also liked the v1.4 f/w from paul (only there was a few spelling errors).

I fixed the error by adding this code
# define __program_start __iar_program_start

It turns out that, IAR5.xx compilers have considerably changed from IAR4.xx the method for the entry procedure.

this code project is build by IAR 4.20 , the newest F/W is also in IAR 4.20

And the V1.1 in LOGO should be the hardware version , now the newest version is V1.3A , and the F/W version is V2.02.

the F/W of V1.X will be open source and everyone can use it as them wish , but the V2.X F/W will not release the source code , because there is some third party code in it and we don't have the authorization to public it.

and the H/W is all open source for all version.

I've a question. The firmware can be flashed through DFU FileManager. However is the bootloader protected. I.e can destroy the bootloader by flashing a wrong firmware thus bricking the device. Or can I always reflash the original firmware restoring the device to it's original state?
