AM3359 ICE setting clock frequency

Other Parts Discussed in Thread: AM3359

Hi all.

I want to change the cpu clock speed of AM3359 ICE demoboard. The default value is 550MHz, as defined in "ti.platforms.evmAM3359".

I followed this procedure:

  1. edit a new custom platform based on "ti.platforms.evmAM3359", with 720MHz clock instead of 550MHz.
  2. selected this new platofrm definition in RTSC options.
  3. cleaned and built the example project (uartecho demo as provided with the sdk) with no error; the console output reflected the new platform selection.
Unfortunately no changes automatically occurred in sys/bios config file (uart_echo.cfg). I didn't find out where select a different platform!
Downloading the binary results in a stop caused by 32768Hz timer mismatch.
Is it possibile to update the cpu clock frequency in an existing project, or I have to create a brand new project?
