I can load the uImage and the created spl-os back and it boots fine. I enabled DEBUG, but I had to make a tweak to the printf statement to get the name of Linux to display correctly. Here is my dump: U-Boot SPL 2016.11-rc3-00009-g050adda-dirty (Oct 31 2016 - 18:29:40) Trying to boot from NAND spl: nand - using hw ecc spl: payload image: Linux-4.9.0-rc2-00040-g9fe68ca-d load addr: 0x80007fc0 si ze: 3869936 Jumping to Linux In order to get to "Jumping to Linux" I removed some of the default memory overrides: >From 050addab9986c35822bbe8f677fb8e7b2c4cb2f6 Mon Sep 17 00:00:00 2001 From: Adam Ford <[email protected]> Date: Mon, 31 Oct 2016 18:19:39 -0500 Subject: [PATCH] OMAP3: omap3_logic_defconfig Use the SPL info inherited from the common TI files. diff --git a/include/configs/omap3_logic.h b/include/configs/omap3_logic.h index 2dcc729..0bff817 100644 --- a/include/configs/omap3_logic.h +++ b/include/configs/omap3_logic.h @@ -19,14 +19,10 @@ * 1MB into the SDRAM to allow for SPL's bss at the beginning of SDRAM * 64 bytes before this address should be set aside for u-boot.img's * header.
