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 doesnt 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????
Im using DSP56303EVM that comes withAtmel flash memory
AT29LV512 20JC and codec CD4215 from Crystal.
thanks
