Other Parts Discussed in Thread: AM3517

What is the clock speed for the GPMC Clock in the current PSP released on the TI website? GPMC_FCLK or CORE_L3_ICLK frequency would tell me this info.

Thanks

The clock tree is represented in the “arch/arm/mach-omap2/clock3xxx_data.c”. You can determine at run time the clock rate for specific modules from the debugfs filesystem.

Specifically in this case on AM3517 – CORE_L3_ICLK should be set to 166Mhz.

There is another clock divider at the GPMC module so the GPMC FCLK should be half the L3 clock or 83MHz.
