TMDSSK3358: MPU frequency

Part Number: TMDSSK3358
Other Parts Discussed in Thread: AMIC110

Hi,

What is the frequency of instruction processing by default when executing the code (also what is its name CORE_CLKOUTM6?) ? There are several clocks in the documantation but I'm lost a bit.

Hi,

The AM335x ARM Cortex-A8 core functional clock is MPU_CLK, which comes from the MPU_PLL. You can find benchmarks here: processors.wiki.ti.com/.../Processor_SDK_Linux_Kernel_Performance_Guide

I'm reading:

AM335x and AMIC110 Sitara™ Processors
Technical Reference Manual

8.1.6 Clock Generation and Management

Which signal is that here?

You are looking at the Core PLL. You need to look at the MPU PLL (section 8.1.6.9):
