SATA support for TWR-LS1021A

[jianwu]

Hello,

I used SD card boot TWR_LS1021 board. I connect TWR-LS1021A with external hard driver. But u-boot cannot detect it. The below is my u-boot log:

What is the correct RCW for SD boot and support SATA, USB etc?

Can anybody send me an u-boot image for sd boot and support SATA3.0 device detect?

Thanks,

Jian

I got SATA works on my LS1021TWR.

Thank Sinan and Yiping's help,

Hello Jian Wu,

You didn't enable SATA in RCW, please refer to the following SerDes options for RCW[128:135].

Please use RSR_PPS_70 RCW provided in the prebuilt images ISO.

Have a great day,
Yiping

Hi Yiping,

Thanks for your help.

Once I boot up LS1021twr with SD card, how can I update RCW with your attached rcw_1000.bin?

Thanks,

Jian

Hi Jian

Can you try this with mainline u-boot and see

if it works. If you have problem with mainline

u-boot, you could then also ask in u-boot mailing

list and I can be also more help as I am more familiar

with mainline u-boot.

Please give it a try with mainline u-boot.

Hi Sinan,

Thanks for your help.

Can you attach your mainline u-boot image binary for sd boot for me?

Many thanks,

Jian

Hi Jian

I don't think there is a way for me to attach a binary file here.

You can generate the binary image yourself :

git clone git://git.denx.de/u-boot.git u-boot/

cd u-boot

git checkout v2015.10

make distclean

make ls1021atwr_sdcard_defconfig

make all

the binary file you need is : u-boot-with-spl-pbl.bin

Try building the image and this way you can also

debug it if it is failing.

If you have problems, send your e-mail address and

I will e-mail you the binary file.

Hi Sinan,

Thanks  a lot for your help.

I got problem to build the SD: u-boot.bin. Could you please send me your SD u-boot binary to try?

My email: jianwu@qnx.com

Thanks a lot,

Jian

Hi Jian

What kind of problems did you have building the u-boot binary.

Can you please send me your build errors.

I will send you the binary in a separate e-mail.

Did Yiping's suggestion not help ?

Please show your build errors here that we can help.
