Other Parts Discussed in Thread: AM1808, PMP

Hi all,

We are using AM1808 based EVM. We have SATA support on our EVM. I have made the following the changes in the kernel configuration for SATA support.


Device Drivers --->
<*> Serial ATA and Parallel ATA drivers --->
                [*] SATA Port Multiplier support
                <*> AHCI SATA support

Then i got the following messages while booting,

ahci ahci: forcing PORTS_IMPL to 0x1                                            
ahci ahci: AHCI 0001.0100 32 slots 1 ports 3 Gbps 0x1 impl SATA mode            
ahci ahci: flags: ncq sntf pm led clo only pmp pio slum part ccc                
scsi0 : ahci                                                                    
ata1: SATA max UDMA/133 irq 67                                                  

But after sometime i got,

ata1: SATA link down (SStatus 0 SControl 300)

This is the first time iam working with SATA on our EVM. Can anybody help me to solve this problem...

Thanks in advance,

Vivek
