TWR-LS1021A rev x3 with rev.2 silicon does not boot attached uboot from SD card.

SW3=off on on off off off off on   SW2=off off on off off on on on

This is error message:

U-Boot SPL 2015.01+ls1+g6ba8eed (Aug 18 2015 - 09:19:58)

spl: mmc init failed: err - -19

### ERROR ### Please RESET the board ###

 

The attached u-boot is programmed into the SD card correctly, I read it from SD card and compared it with original.

I tried the same attached u-boot and SW3, 2  settings on LS1021A rev x3 with rev.1 silicon and it does boot from SD card!  

 

What does "spl: mmc init failed: err - -19" mean?

Any suggestions?
