Dear all,
Im' quite a bit confusing with SATA on my OMAPL138 Experimenter(SOM in revision B or C).
With the kernel version provided with the DVSDK which is 2.6.37, everything is working well with SATA. My SSD hard drive is recognized properly by the kernel at startup. I can mount a partition and do any file writing or reading to/from the hard drive, from my application as well as by FTP.
As I saw that supports for OMAP L138 is now done into the mainline linux tree, I would expect booting my board with a newer version from linux kernel: 3.4.4. What I have done! Unfortunately, SATA is not "recognized" well at linux kernel startup
Please find below error from linux kernel startup:
ata1: link is slow to respond, please be patient (ready=0)
ata1: softreset failed (device not ready)
ata1: link is slow to respond, please be patient (ready=0)
ata1: softreset failed (device not ready)
ata1: link is slow to respond, please be patient (ready=0)
ata1: softreset failed (device not ready)
ata1: limiting SATA link speed to 1.5 Gbps
ata1: softreset failed (device not ready)
ata1: reset failed, giving up
I have already disabled SATA PM Multiplier into the kernel without any success as suggested into the post: http://e2e.ti.com/support/dsp/omap_applications_processors/f/42/p/31969/123553.aspx#123553
Do you have any idea about te issue?
Thanks in advance for your answers.
