Hi

See:
http://www.utasker.com/docs/uTasker/uTaskerFileSystem.PDF
(also http://www.utasker.com/docs/uTasker/uTaskerFileSystemSPI_FLASH_002.PDF if you may be interested in saving larger amounts fo data to SPI based FLASH).

File system and parameter system support with open-source code is available in the uTasker project - this is completely free for non-commercial work and includes support at the uTasker forum: http://www.uTasker.com/forum/

Hi,

I sent you an e-mail, but just in case it takes you as long to notice you have a message as it took me :smileyhappy:, I thought I'd repeat the e-mail here...

I think you want to use 0x3fffc rather than 0x3ffff, to get a word-aligned address.

(I tried that with your code and it worked!)

Hope that helps!
