DSPPLL_CLKCTRL register value of AM3874

Other Parts Discussed in Thread: AM3874

Hi,

I have one question regarding DSPPLL_CLKCTRL register of AM3874.

According to the TRM(SPRUGZ7B) 2.10.1.18 DSPLL_CLKCTRL , the register value is 914824h after reset.

But according to our customer's analysis by emulator,  the register value is 09910812h. And also other CLKCTRL registers are same value.

Is reset value of registers in TRM correct? Please let me know.

Best regards,

Michi

    Hi Michi,

    The reset value of the DSPDPLL_CLKCTRL that I read on my DM814x/AM387x EVM (TI8148-GP rev 2.1) is 0x08110811. Definitely we have an issue with this value. I will check with our design engineers and let you know if/when I have something more.

    P.S. Please note this DSPDPLL_CLKCTRL register is not used in our u-boot or  linux kernel when configuring the DSP_DPLL.

    Regards,

    Pavel
