[beagleboard] GPMC Parallel NOR boot using BeagleBone Black.

Hi, Can I do GPMC XIP parallel NOR boot using Beagle Bone by using the expansion headers of the beagle bone and making my own custom board for NOR / OTP Flash and check it. What can be the probable issues which I can face in doing this as most of the header signals are shared on BBB? When

Because you are not "assigning" a speed. You are setting a "maximum" speed, and the system is free to generate any standard available frequency slower than the maximum. Because of the clock divider chains feeding the SPI, it is not possible to generate any arbitrary speed. You may be able to

emmc card can't be removed. Did you mean SD card has to be removed? Sysboot will ensure that BOOT-ROM will setup the peripheral/pinmux rightly to boot from that medium. But after the OS starts it might have its own set of pinmux which needs to be set rightly to access that medium. cheers, -ro
