IMX6SX NAND Boot

[hengyewlim]

WinBond NAND device connected to iMX6 SoloXGPMI nand controller is not booting up.

NAND device can be detected by U-boot and Kernel.

Strange Bad Blocks detected on Block 0 and 1 which is guaranteed by manufacturer.

I have setup the IOMUX for NAND in both u-boot and kernel dts file.

I have attached the logs from the serial console.

Hello,

  Please look at my comments below.

   NAND is supported on i.MX6 SABRE-AI platform, assuming NXP Linux BSP.

Please refer to the following thread for more details how to boot from NAND.

"How to boot from NAND Flash"

< https://community.nxp.com/message/642374#comment-642374 >

   Please use the MFG tool for NAND preparing, as mentioned in the following discussion 

"i.MX6 boot from Nand flash"

< https://community.nxp.com/message/575636#comment-575636 >

  More information about NAND parameters are provided in FCB (Firmware Configuration Block) on the

NAND. It should be written by the kobs-ng utility dufing MFG session.

Have a great day,
Yuri
