I'm booting form a SD card on our LS1021A board but FLASH type does not appear to be specified by the RCW or the hard coded pullups on the IFC_AD signals. It appears its defaulting to serial flash..

 

I get "Bank # 1: missing or unknown FLASH type" when I type flinfo. Writes do not work and reads yield 0s. 

 

The boot log says:
