Understand configuring UBOOT for the X15 specifically SATA

Hi Everyone,

I am new to the X15. I have an XM since it came out and have done many projects with it. I have recently purchased and X15. My desire is to boot from a SATA drive connected to the ESATA port. I have verified when booted from the MMC card the SATA drive is bookable, I can mount the sata drive and it works well. I imaged the SATA drive with the X15 image, In my case SDA1 is the first partition created. I have removed R444 and placed a jumper I believe what is J3 pins 1-2 and have left the R444 resister solder points/mounts empty( “desoldered R444 only” ). When I try to boot off of the SATA drive the board times out and powers down. The instructions are a little vague on the on instructions with in the user manual. I had a similar problem when the partition was enlarged on the MMC card to 32 gigs, the boot process would timeout. I used the grow_partition.sh script which fixed the time out issue with the MMC card. To make I am viewing the board correctly, I hold the X15 board orienting J3, J4,J6 at the upper right corner hand corner, And join pins 1-2 – most left hole moving right towards the center pin, there orientation is horizontal I believe. The board as I mention powers up and then times out and shuts down. If the MMC card is inserted the board bootsd up fine on the MMC card. I have also purchased two boards at a pretty steep price and would like to pass them out to family members with the hopes of purchasing additional boards. But the ESATA/SATA issue is stopping me and I don’t want to return the second board to DIGIKEY. I can’t return the first board well because I modified it by removing the resistor.

Is the image I used on the SATA drive incorrect or need an adjustment? Are the PIN orientation as I understand it incorrect.

Held the X15 so that the ON switch is the upper left and jumpers are upper right hand corner.

The drive spins up when I power up the board. So I know the ESATA port is powering up with the board.

What should my U-Boot settings look like. Please be explicit

I have also run ( apt-get -y update && and apt-get -y upgrade )

Can you please help? Is there an alternate way of booting off of the ESATA port.
Please be explicit

Thanks in advance
