We built PCB's using the OMAP L138 chip following the design guides closely, however we are having issues with the OMAP chip talking the the memory. When we run the memory test it fails and gives this error message:
| "--- Test address and data bus ---addr/data bus test failed at address: 0xC0000000test_data: 0x00000001*test_addr: 0xFFFFFFFF" |
Any suggestions on troubleshooting this problem? We have looked through a lot of the material provided by TI on the website already and haven't had any luck yet.
