Hi, Everyone

I have a question about AM335x of ISDK.

I saw GEL file on ISDK and CCSv6
ICEv2 board has 800MHz of AM3359.
but It is work on 600MHz.

Why AM335x's frequency is 600MHz on ISDK ?

Hiroyasu-san,

AM335x SOC has three operating points as you can see in section 5.4 of the datasheet. OPP100 , OPP120, OPP_turbo. The MPU voltage setting on the EVM is configured by default to support OPP_120 so the software has been configured to use 600Mhz (max frequency at OPP_120)

You can use 800Mhz, on the EVM but you will need to modify the PMIC settings before changing the clock setting to 720Mhz or 800Mhz.

Regards,
Rahul
