Hi,
I have a IMX53 Sabre Tablet that boots from MMC and running Linux freescale 2.6.35.3-1129-g691c08a.
I am trying to set it up for booting (u-boot) from SATA upon power up. I did the following to copy MBR/u-boot from MMC to SSD and apply the workaround for SATA internal clock issue as described in the Release notes (log below at end of email).
I set SW26[4,6] = 1, 1 and all other in SW26 and SW28 to 0. After pluging back the power cable and hiting power/reset button, there is no output on the serial console (Debug Card RS232)
The IMX53 part number marked on the IMX53 Sabre Tablet in lab is “PCIMX535DVV1B”
Am I missing any configuration/step for setting up the board for SATA boot? Can someone please help me to understand what the problem could be?
(I am able to detect SSD in Linux, boot kernel image from SSD and mount root filesystem on SSD partition)
Thanks in advance.
Regards,
Ravi.
