[U-Boot-Users] Problems accessing flash on OMAP 1510 Innovator
I'm trying to install and run u-boot in an OMAP Innovator 1510 board. I've downloaded the CVS version of u-boot, configured it with "make omap1510inn_config" and compiled it with no problem. It's installed in the flash and runs. The problem is the flash can't be found -- on startup up Flash: 0 kB is reported and I can't save anything. Other flash accesses are similar. Sample output follows where I've powered on the board, run "flinfo", and tried to do a "saveenv".
Any help would be appreciated.

Hm, I just did `cvs up; make omap1510inn_config; make`, installed latest binary and it works OK for me. Are your DIP switches set correctly (usually 1,2;4 OFF, 3 ON)? FWIW, here's console log for my board:

Perhaps you can try this to see what's wrong with your flash?:

I should point out that I've been using the board for about the last year and a half, but with rrload. I decided to switch over to u-boot and ran into these problems. A little investigating revealed that in the function get_flash_size() in the file board/omap1510inn/flash.c, the probe for manufacturer returns 0x12 and that doesn't match INTEL_MANUFACT which is what's on the board. After that things go downhill very rapidly. I think I'll look into what's going on in rrload to see if that will explain things.
Thanks for the help so far.
