(SATA) softreset failed issue and link speed is 1.5Gbps DM8168

Narthan,

Are you using EZSDK 5.05.02.00? What is the silicon revision of your DM816x device (2.1, 2.0, 1.1, 1.0)? Are you using SATA GEN3 device?

Regards,
Pavel

Dear Pavel,

Nice to see you again, thanks for your response

Please find the following details in our customized board.

1: Sata related Details:  MO-300 mSATA Module
                                           Compliant with SATA III and SATA v 3.0 standard 

2: EZSDK : ti-ezsdk_dm816x-evm_5_05_02_00 and also tried with the latest linux source for the ti-git    (linux-omap3 (version : 2.6.37)).

Processor silicon Version: (DM8168CCYG ---> 2.1ver)

If you need any other information, please let us know........

Thanks,

Narthan S

Narthan,

Are you using external 100MHz differential clock source for the SATA PLL (not 20Mhz osc)?

Dear Pavel,

thanks for providing inputs and links related to SATA

we probe SATA PLL that clk source having 100 Mhz.

and we tried with the Kingston 60Gb (SATA Rev. 3.0 (6Gb/s) support) is detected with the link seed 1.5Gbps

Same uImage and Kingston device with EVM Dm8168 board the link speed is in 3Gpbs

What may be the issue ???

Whether Dm8168 supports SATA Gen 3, Or SATA Gen  2,  Or SATA Gen 1 ?

if SATA Gen 3 is not supported, do Any pach to support SATA Gen 3 ?

and we tried Adventec SATA Gen 3 device (toshiba chip) is not detecting and continuously soft reset will happened and finally it will fail.
