Tool/software: Linux
Hi All,
We are facing a serious issue with respect to TLK10232. We made a customized design with T4240 Processor along with the TLK10232. We are using U-Boot version - 2016.01 and kernel version - 4.1.8 . TLK10232 mdc and mdio are connected to the T4240 Processor. Input reference clock is 156.25MHz. Pins That are hardwired,
PRTAD[4:0] - 11011,
ST - 0 and
MODE_SEL - 0
We have followed the below steps for checking the 10G BASE-KR,
mdio write 0x1E.0x0 0x8610
mdio write 0x1E.0x001D 0x0000
mdio write 0x07.0x0 0x20000
mdio write 0x01.0x0096 0x0000
mdio write 0x1E.0x8020 0x03FF
mdio write 0x1E.0x0004 0x9500
mdio write 0x1E.0x0003 0xD500
mdio write 0x1E.0xE 0x0008
Then we read back the Link status,
mdio read 0x1E.0xF ==> 0x0 is showing. we have enabled the Linux and we tested the status of the particular port, It is detected as
ethtool fm1-mac9
Settings for fm1-mac9:
