It allowed me to boot my eSATA SSD from an SD card without removing R444 and jumping J3 pins 1-2.

Special thanks to Angel Sosa for his 22 steps towards the end of the thread.

Here is my uEnv.txt in the /boot directory on the SD card I use boot to the eSATA SSD.

The /etc/fstab for the eSATA drive was UUID=ea682c27-2bc8-461e-9d1b-420705edd1ce  /  ext4  noatime,errors=remount-ro  0  1

went to lower case uuid and comment out the "/  ext4  noatime,errors=remount-ro  0  1"

My performance is improved also:

sudo hdparm -tT /dev/sda

[sudo] password for debian: 

/dev/sda:

 Timing cached reads:   1958 MB in  2.00 seconds = 979.65 MB/sec

 Timing buffered disk reads: 776 MB in  3.00 seconds = 258.40 MB/sec

Thanks again for a good thread.
