Hi all.

I have a program that writes code to flash memory in the DSP56303EVM, and I have proved with some programs involving SCI, ESSI, etc. and they worked fine.

 

The problem arrives when I write into the flash an application with DMA. the application has a data transfer with ESSI controlled with DMA. The application alone works fine, but running form the flash, it doesn´t work fine. The data transmited are different (way to different) from the data that is expected.

 

Is there any consideration that maybe I have not taken into account? Does it change in anything the fact that the code is running from the Flash memory rather than intern memory????

I´m using DSP56303EVM that comes withAtmel flash memory  AT29LV512 20JC and codec CD4215 from Crystal.

 

thanks
