Hello,

I've just started putting together support for a NAND Flash part that we have on a custom iMX6 design running QNX 6.6.0.
 I've seen that ETFS is the higher level component in the stack that ostensibly takes care of bad block handling. From a
 web search, I came across an ETFS port for early BBB (2GB part) for 6.4.1. 

Are any other 'official' examples and/or documentation on ETFS and/or how to properly write a NAND flash driver for QNX?
 Does one exist for iMX6 or it's predecessors (iMX53/51)? Although it appears that the iMX6 uses a new General Purpose 
Media Interface (GPMI) block, with a new ECC block that may not have been implemented on the earlier SoC's. Freescale 
has some example code for the iMX6, and that's what I'm working with now. 

Thanks, and Best Regards,
Tim Meese
