66AK2L06: Keystone II SERDES Ref clock configuration in Uboot

kheng sim yeoh

Part Number: 66AK2L06

Hi,

We have a custom board that using 125Mhz as SERDES reference clock which different from the EVM (156.25Mhz).

I need to change the setting in uboot but couldn't find where the file located. Found on this thread https://e2e.ti.com/support/dsp/c6000_multi-core_dsps/f/639/t/501793, but the file path u-boot/drivers/net/keystone_serdes.c is not valid.

Can you provide us where is the location?

Thanks,

Hi Yordan,

Thanks for your reply. I found it in the path drivers/soc/keystone/keystone_serdes.c.

In the PDK SERDES source code I only can see example to set 125Mhz_10bit_5Gps (/ti/pdk_keystone2_3_01_04_07/packages/ti/csl/src/ip/serdes_sb/V0/csl_wiz8_sb_refclk125MHz_10bit_5Gbps.c)

Do you have example code for 125Mhz_10bit_1p25Gps.

Thanks,

Hi,

Sorry I thought you were using linux SDK.
Anyway I've asked the RTOS team to help. Their feedback will be posted here.
