P2020 1.33Ghz problem

Hi All,


P2020 1.2Ghz board is designed and used well.

On a good board, we changed the CPU to 1.33Ghz(P2020NSN2NHC) as shown below.

SYSCLK : 66.66MHz

cfg_sys_pll[0:2] : 011 (8:1) - 533MHz

cfg_core0_pll[0:2] : 101 (5:2 (2.5:1)) - 1333MHz

cfg_core1_pll[0:2] : 101 (5:2 (2.5:1)) - 1333MHz

I am using SD-Card booting but I do not see SDHC_CLK output.

I do not seem to have any problems with the settings, but I do not work.

Is there any hardware difference between 1.2GHz(P2020NSN2MHC) and 1.33GHz(P2020NSN2NHC) models?


What is more updated than P2020RM rev2? There is no content for 1.33GHz.


Thank you.
Best regards,
