Dear All ,
I am using F2812 for long time and my product works fine.
For some new feature developments, I changed memory allocation. Previouly I was fitting most of my PAGE 1 section in internal RAM, though my hardware is having external SRAM. Now because of size limitation I need to shift my some PAGE 1 sections to external RAM. With this chage my system started behaving erractically. The immediate effect is key board fuction. Say out of 20 keys few are working others are not responding. If I check in those keys in Single step , I get proper response.
This problem I could locate after doing similar changes on my working version but I do not under stand reason behind. Does any any one know why this can happen? my extenal SRAM IC is 256K cypress SRAM with 15ns timing.
I will appreciate if some one gives me correct reasoning.
regards
Abhijit Kelkar
