Platform Flash LX doesn't support 0xF0 reset command

Description

After successfully programming the Platform Flash LX the FPGA cannot boot from it unless a reset of the flash is performed.

Solution

Usually INTEL flashes have a reset command (0xF0) that can be issued by software to set the flash back into read mode after programming.

The Platform Flash LK does not support this command.

The ready array command 0xFF can be used instead.

See http://www.xilinx.com/support/documentation/data_sheets/ds617.pdf  for more information on the supported commands for the Platform Flash LX.
