Customer can boot Linux on Zedboard,but not on custom target board. Note that Linux was previously booting the target board with 2013.3 and the customer decided to move to 2013.4, when this seems to have broken. The customer is using the 2012 Linux Speedway as a reference.

It looks as if it is failing during the FSLB. The .BIT file is not loading.

Hi Tim,

Xilinx made a change in the SD 'driver' in the 2013.4 FSBL to monitor the status of the PS SDIO WP pin. If this pin is not connected on the custom board that could be the issue. If this is the issue one potential fix is to go into the PS config and bring the SDIO WP pin out to an EMIO pin and tie it to '0' using a 'constant' IP block.
