We have a T2080 Custom board with T2080RDB as the reference design and we have selected the SerDes Protocol as 0xF8 and 0x36. A clock of 100 MHz is provided as the reference to the PLL2. On our SerDes2 Lane G, we have connected a 16Gb SATA NAND Flash (GreenLiant GLS85LS1016B-M-C-FZJE-ND102).
Once we boot the VxWorks and register the vxbFslSataStorage driver, no SATA device is detected and no device is created under devs.
I tried following the steps in 22.5.1 SATA controller initialization steps od Rev3,2016 T2080RM, there I'm getting status as
IPM : Device not present or communication not established
SPD : First-generation communication rate negotiated.
DET: Device presence detected but PHY communication not established
HS_ON : The SATA controller is operational.
HS_OFF : Host is not in process going offline
OP_MODE : The host controller is operating in legacy mode.
PR : Phy Not ready.
I'm new to SATA, I want to know whether there is a way to check the physical link between SerDes and SATA device is fine? Any Register read which will tell the Physical link status?
