Dear all,

-DMA_Wait(ERROR_DDI_NAND_DMA_TIMEOUT)

Flash PDD Error: Function: FlashPdd_IoControl,  Line: 365-DMA_Wait(ERROR_DDI_NAND_DMA_TIMEOUT)

Flash PDD Error: Function: FlashPdd_IoControl,  Line: 365-DMA_Wait(ERROR_DDI_NAND_DMA_TIMEOUT)

Hi

please look how support new nand

Adding Support For a New NAND with i.MX28 on Wi... | NXP Community 

also it is needed to build special version of WinCE (supporting new flash) for
the MFG tool.  
The following solution is included in the BSP that provides the workspace for
building the MfgTool Windows Embedded CE 6.0 firmware run-time image:

WINCE600\OSDesigns\iMX28-EVK-PDK1_9-UUT

UUT is version that is intended to be loaded by the MFG tool to SDRAM of a
target system and interface with the MFG in order to get target images and write
them to SD or NAND. It is one, located in  firmware directory :

<mfg_dir>\Profiles\MX28 WinCE Update\OS firmware\uce_ivt.sb

Best regards
igor

Hi

I have had this issue. A bug in the nand driver has been revealed by a microsoft update back in 2014 that causes the dma timeout.

See my post https://community.nxp.com/thread/376307

I have a fix and should be able to post it tomorrow when back in the office
