On T1040 base board we are using serdes protocol -0x69 ;we have sgmii interfaces on:
X1 on Lane1-FMmac3
X1 on Lane6-FMmac4
the above sgmii links are connected directly to SFPs without any PHYs as in RDB.
Do we have to program SerDes_SGMIICCR1, SerDes_SGMIIDCR1 registers to set the dummy phy device addresses?
I added the following lines in u-boot in int misc_init_r(void) function to initialise phy addresses as 0xc and 0xd to lane1-sgmii and lane6-sgmii respectively:
u-boot prompt is not coming, after adding above lines.It hangs after executing above lines
please let me know what is the issue.
Thanks in advance,
