Hi,
I'm now using AM3352BZCED30(that is, 300Mhz) with EZSDK 5.5.
Since the CPU supports up to 300Mhz, I'd like to configure its cpu clock as 300Mhz. Currently, VDD_core is 1.1V. But clocks_am335x.h has only following configuration.
There is no setting value for 300Mhz and now MPUPLL_M_500 is being used. What should I do for 300Mhz support?
There will be no issue even though I use MPUPLL_M_500?
#ifndef _CLOCKS_AM335X_H_
#define _CLOCKS_AM335X_H_
/* Put the pll config values over here */
#define OSC 24
/* MAIN PLL Fdll = 1 GHZ, */
#define MPUPLL_M_500 500 /* 125 * n */
#define MPUPLL_M_550 550 /* 125 * n */
#define MPUPLL_M_600 600 /* 125 * n */
#define MPUPLL_M_720 720 /* 125 * n */
#define MPUPLL_N 23 /* (n -1 ) */
#define MPUPLL_M2 1
/* Core PLL Fdll = 1 GHZ, */
#define COREPLL_M 1000 /* 125 * n */
#define COREPLL_N 23 /* (n -1 ) */
#define COREPLL_M4 10 /* CORE_CLKOUTM4 = 200 MHZ */
#define COREPLL_M5 8 /* CORE_CLKOUTM5 = 250 MHZ */
#define COREPLL_M6 4 /* CORE_CLKOUTM6 = 500 MHZ */
/*

* frequency needs to be set to 960 MHZ. Hence,

*/
#define PERPLL_M 960
#define PERPLL_N 23
#define PERPLL_M2 5
/* DDR Freq is 266 MHZ for now*/
/* Set Fdll = 400 MHZ , Fdll = M * 2 * CLKINP/ N + 1; clkout = Fdll /(2 * M2) */
#define DDRPLL_M 266
#define DDRPLL_N 23
#define DDRPLL_M2 1
Thanks and BR,
