sys bios: cpu clock frequency in BIOS->platform settings

Hi NewBee,

When using SYS/BIOS, the easiest way to configure the PLL is to pull in the Boot module in the *.cfg script and program the PLL input clock freq and DIV & DIVSEL ratios. Boot module will accordingly compute the CPU freq and set BIOS.cpuFreq.lo/hi fields in BIOS.

Here's a screenshot showing how to add Boot module to your config:

I tried to set frequency but I get error in BIOS block showing set frequncy becomes 0.

Also not able to see frquency=100MHz in Boot block.

What is the problem.

Newbee,

Did you try adding the Boot module and selecting "Configure PLL" ? Can you share your *.cfg file and the error message you are getting ?

I am frustrated here.

When I try to do: Configure PLL with  PLL input clk (Osc)= 20

PLL control register-DIV= 10

PLL status register -DIVSEL= 2

It shows frequncy 0 and also at boot section CPU clk frequency becomes 0.

It is leeting me to set 100Mhz when configure PLL is selected.

PLL configuration is available for TMS320F2808 ???

NewBee,

I have the same problem, I did not see the resolution the this case also it marked as answered

Thanks,

David.
