Honored ContributorI really appreciate your help slacker. Thanks.
Hopefully I can pick your (or anyone elses) brain for one last issue. I've loaded the mem test program onto my development board but adjusted it so that I'm running out of the ext_ram (SRAM) and am trying to exercise the test routine on the SDRAM. I'm running into an issue where I get data corruption (the program 'crashes') if I run the test on addresses starting at 0x0100.0000 (which is SDRAM_BASE). However, I have no issues running the test at 0x0100.01c8 (VMA + LMA as reported in the objdump) and beyond. Am I understanding it correctly that my SDRAM addresses are simply adjusted during the compile? Therefore, when I run the test at SDRAM_BASE, I'm in fact really adjusting some other memory in the system space? If so, is there any way to dynamically hard code in what the SDRAM addresses will be? Or am I just way off and have a seperate issue at hand. Thanks again, Keivn
