DM814x DPLLLJ calculator

Andrea Scian

Dear All,

is there any tool to help in configuring DPLLLJ on DM814x?

I found something similar to what I need but they say it's for for TMS570 microcontrollers: http://e2e.ti.com/support/microcontrollers/hercules/f/312/p/36777/228306.aspx#228306

(BTW, I need to change DPLL Audio to use it as mcasp master clock on our design)

Best Regards,

Andrea

Hi Andrea,

Can you use the details in this wiki page and change the clock rates according to your needs

Thanks Anil,

I was looking for a standalone tool but linux clock infrastructure looks good for me.

I'll write some code and, if needed, I'll take a look at PLL parameters (M, M2, N) via JTAG or devmem2

Best Regards,

Andrea
