can we change rcw[127-135]=0xA7 while using t1040rdb for baremetal board?

[loliyana_jay199]

hello 

i have doubt i am using t1040rdb so we require RCW for that in that we have serders protocol what it means ?

in rcw we declared 127-135 = 0X66 can we change that value to 0XA7 ? and other thing is what that 0x66 is exact for?

how we will get that value ?

Have a great day,

You should set RCW[128-135] (SRDS_PRTCL_S1) in accordance to the serdes lanes using on the board. You can see required values in the T1040 reference manual Figure 31-1 "Supported SerDes Options". You can find that SRDS_PRTCL_S1=0x66 sets the corresponding lanes to support QSGMII and SATA interfaces used on the T1040RDB, while SRDS_PRTCL_S1=0XA7 does not.
