Does the TWR board support SATA?

[hwei]

I get an ls1021a TWR board, and there is "SATA basic support" in SDK 1.2 RN, but how to enable this SATA support?

I have tried to change SW3[6], but the result is still the same:

SATA link 0 timeout.

AHCI 0001.0300 1 slots 1 ports ? Gbps 0x1 impl SATA mode

flags: 64bit ncq pm clo only pmp fbss pio slum part ccc

scanning bus for devices...

Found 0 device(s).

Besides that, I cannot access any SATA devices in kernel too.

Does the TWR board come with SATA support? If so, how to enable it in u-boot and kernel?

Thanks

I just took a look at what comes with SDK images. On the SDK

use one of the images in ls1021atwr/rcw/RSR_PPS_70. In that

directory name 70 refers to Serdes Protocol 0x70 and it enables

SATA1 on Lane B. Use one of these images as your RCW and boot

your board with it. You should be able to see SATA enabled.

Hi Sinan,

Thanks for your reply.

I have tried to set Serdes Protocol to 0x70, but I still get the same result:

Hi H Wei

OK, I have to debug this and see what that SDK uboot has implemented.

Meanwhile, I am just curious, are you getting similar results with Linux

kernel as well ?

Hi Sinan,

No matter what I try, the result in kernel is still:

root@ls1021atwr:~# ls /dev/sd*

ls: /dev/sd*: No such file or directory

Thanks

Hello H Wei,

In the recent LS1021A Linux SDK(1.2), only Sata disk detecting is supported in u-boot, SATA Linux driver is under developing now.

Have a great day,
Yiping

Hi Yiping,

Does the SATA drive get supported in SDK 1.7?

I find it still doesn't work on my board.

Thanks

[yipingwang]

Hello H Wei,

SATA 3.0 doesn't get support in SDK 1.7, it is still under investigation.

Thanks,

Yiping

Hi H Wei, you will probably have to make sure SRDS_PRTCL_S1[128:135] RCW

value is set accordingly for SerDes protocol that configures the board to use SATA. I am

not sure if there is a prebuilt RCW image available for this as part of SDK at this

point.

Hope this helps.

Hi H Wei

What RCW are you using to test out your SATA ?
