DSP56F807 Programming flash - Lionel Degoutte - Oct 14 8:57:00 2003



Hello,

In metrowerks codewarrior 5.2.1177, (with DSP56F807 demo board, and SDK 3.0)
what is the difference between using or not using the option "use flash
config file" in "flash setting -> M56800 Target setting".
When i use it, the transfert into target is very slow, and it works.
When i don't use it, the transfert is fast, and it doen't works : the conter
program jump directely in "asm void configUnhandledInterruptISR (void)".
Why ?

Thank you.

You need to use the flash configuration file when programming and running from flash. The codewarrior tool uses this file to determine how to program the flash in the part. When it is not specified CodeWarrior defaults to something that is not correct for the part you are using and hence it does not properly program the flash. Thanks.
