Hi,

I cannot detect nand on u-boot for AM335X-EVM.

Anyone can give me MLO,u-boot.img that you can run properly for recongizing you EVM.

I dont know why my built u-boot cannot detect nand.

Thank you very much.

Hi Judy,
The NAND is supported in the default u-boot build.
For example, running "nand info" @u-boot prompt using SDK 6.3 u-boot build on AM335x GP EVM.

=> nand info
Device 0: nand0, sector size 128 KiB
  Page size       2048 b
  OOB size          64 b
  Erase size    131072 b
  subpagesize      512 b
  options     0x0000400c
  bbt options 0x00008000

Please see CPLD/profile sections on how to select required peripherals via DIP switch SW8 (under LCD on GP daughter board).
processors.wiki.ti.com/.../AM335x_General_Purpose_EVM_HW_User_Guide
For example, profile 0 (SW8[4:1] = OFF) is one of options to select NAND.
Best,
-Hong

Thank you,

my evm cannot detect nand.

I bought a used evm, and this one recongize nand.

So, it is not s/w issue.
