FYI - I just uploaded an msp430f1611 FlashBridge implementation to TinyOS 1.x CVS under /contrib/rincon/apps/FlashBridge. This will let your applications read, write, erase segments, and calculate CRC's on data stored in the msp430's internal flash. Similar to InternalFlashC in a way, but with more control over the flash and access to the full 256 bytes instead of 128 bytes.
A demo that lets you interact with various flash types from your computer is located in /contrib/rincon/apps/FlashBridge/apps/FlashBridgeViewer. You'll need parts of the /contrib/rincon directory to get this demo app to compile, so just download the whole /contrib/rincon directory. Make sure you edit the Makefile to select the flash type you want to interact with. I'll probably upload another implementation soon that provides the same interface to the avr's internal flash. -david -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Joe Polastre Sent: Tuesday, August 22, 2006 3:50 PM To: Chong Hui Kim Cc: tinyos-help@Millennium.Berkeley.EDU Subject: Re: [Tinyos-help] Howto use InternalFlash on Tmote Programs like Deluge allow you to upload new programs without completely erasing the internal flash. if you use the BSL, your only option is to erase all flash, including internal flash.
