Nand Flash problem

Question asked by PRAMOD KUMAR on May 29, 2015

Hello,

 

We are working with the Toshiba NAND  TH58NVG5S0FTA20(4GB, 2CE) .Nand Flash was detected in kernel and kernel image linux.sb  port using kobs-ng command.

When we boot the board in NAND mode it was not able to boot and  error code

0x80508002 Unable to find NCB was serial out.
