Hi,<br><br>System details:<br>Linux: 2.6.26-1<br>Processor: MPC8313<br clear="all"><br>The
current freescale NAND controller driver is using &quot;command completion
(CC)&quot; interrupt from FCM block to know the completion read and write
operations. After issuing NAND read/write operation and before FCM CC
interrupt, access to other Local Bus chip selects will failed. I have
found that it was a limitation with freescale FCM block.<br>
To come across this limitation, i have implemented busy wait loop in driver.<br><br>I
have spent lot of effort to find root cause, so that i would like to
publish my observations here which may help somebody who is using
MPC8313.<br>-- <br>--Amru<br>
