Part Number:OMAP-L137
Hello,
I'm using an OMAP-L137 and trying to boot from external NOR flash (Cypress PN: S29GL064N90TFI030) that is attached to EMIFA. My boot pins are set accordingly (verified on a scope as the OMAP comes out of reset):
BOOT0: 1
BOOT1: 0
BOOT2: 0
BOOT7: 0
We are giving the OMAP a 26MHz clock on its OSCIN pin (OSCOUT is floating), but when the OMAP comes out of reset, I do not see any traffic on any of the EMIFA lines. I have an OMAP-L137/TMS320C6747 Floating Point Starter Kit that I set the boot mode identically to my hardware, and I can see it toggle the nEMIFA_CS[2] a few times when it comes out of reset. This leads me to believe that it's more something going on in the firmware than the hardware... but I'm more a hardware designer than firmware, so I'm a bit lost on other things I can check to help narrow down the root cause of my issue.
Any help would be greatly appreciated!
