On 7/13/12 fjrg76 asked, “I’m currently using CW 2.0 for developing, however I can’t find where the memory map is. What I want to do is to download the code into the external RAM while in develop. Besides all that external RAM seems to be used.It also seems that external FLASH is not being used, it’s a waste of memory!!”

(Follow up post)Answered:
Running code from external RAM is not recommend is it will incur a significant slow down in performance.
The memory map is found by right clicking on the project and selecting “View Memory Map (as text)”. The key areas are “Flash” and “SDRAM” only.
The external memory can be used, but the Crossworks compiler does not have a way to write directly to it. Usually custom code must be used to write to it via the Flash drivers.
