Hi, We've mounted a 32kB external SRAM on an Eval ADUC 842 board (using U6 and U7 locations). Which configuration should we use in the startup file and SFRs? Has somebody a working example (with source code) so as to ensure that component are properly soldered? (I've tried today to code a litlle program to test that, allocating and reading a large array, but without success, so I want to isolate hardware and software problem) Thanks for your answers, Lionel
Read Michael Barr's article on memory testing: http://www.embedded.com/2000/0007/0007feat1.htm It both explains the types of faults that can occur in memory systems, and presents code to detect them!
