Hi, System details: Linux: 2.6.26-1 Processor: MPC8313
The current freescale NAND controller driver is using "command completion (CC)" 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. To come across this limitation, i have implemented busy wait loop in driver. 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. -- --Amru
