Hi,

This is described in the AM335X Technical Reference Manual Rev. K (http://www.ti.com/lit/ug/spruh73k/spruh73k.pdf ). Check "Connectivity Attributes" part in the section of the module of interest.

You can also download the AM335X Clock Tree Tool (http://www.ti.com/tool/clocktreetool )

hi biser
In trm-spruh73k table"8-29",is there a register called"CM_PER_L4FW_CLKCTRL" offset 0x64?
It is exsiting in the starterware code but not in the trm table"8-29".I need this reg to check the L4FW's clock status.

Registers that are not listed in the TRM are not available for user modification.

Just checked an older version of the TRM. The structure of the CM_PER_L4FW_CLKCTRL register is identical to the CM_PER_L4LS_CLKCTRL register.
