Linux/LINUXSDK-OMAPL138: Boot failure

Thank you for your reply.

The primary difference between OMAP L138 LCDK and my design is the part number of DDR chip and NAND FLASH chip.

OMAPL138 LCDK：

NAND FLASH ,Part Number：MT29F4G16ABADAH4：D， Density 4Gb,Device Width:16bit,MICRON

DDR-2 ,Part Number：K4T1G164QF-BCE7,64M×16，84 FBGA，SAMSUNG

MY DESIGN：

NAND FALSH ，Part Number：S34ML04G100TFI00，Density(bits)：512M×8，SPANSION

DDR-2 ，Part Number：MT47H64M16HR-25EITH，64M×16，84 FBGA，MICRON

Linux version 3.3.0+ (tl@dsp) (gcc version 4.3.3 (Sourcery G++ Lite 2009q1-203) ) #8 geda027b5 PREEMPT Sat Jul 22 08:50:24 CST 2017

Thank you very much for your reply.

1、On the hardware, I checked and found that the Nand Flash data pin was shared with the ADC data pin. I didn't know if it would cause a startup error.

2、I 've had 100 power-on tests these days, five of which failed, and the error message is as follows:

（1）NAND read from offset 120000 failed -74

** Read error
