Hello
I want to set secondary clock CLOCK GEN2 in EVMK2H. I want to set a SRIO clock to 100Mhz
BMC command has PCIE clock mux command. but BMC command has not SRIO clock mux command.
How to change a SRIO clock 156.25Mhz to 100Mhz?
My board is EVMK2H Rev 4.0. and BMC ver is 1.0.2.6
Regards.
Shin.
Hi,
There is no MUX selection for SRIO reference clock. MUX selection is only for PCIe reference clock for more information refer section "2.4 Clock Domains" on EVM technical reference manual.
The MCU is control the MUX selection for internal and external PCIe reference clock to SOC. By-default MCU is configured as internal PCIe reference clock, If you using external clock means you need to change the MCU MUX section.
For SRIO, you cannot configure the SRIO reference clock for 100MHz. This is not a valid frequency for the SRIO reference clock. Only 156.25MHz, 250MHz or 312.5MHz can be used as a reference clock for the SRIO.
