Hi,
We have designed board with ARM (66AK2H14) processor and 512MB NAND FLASH
Built the u-boot using commands,
make clean
make k2hk_evm_defconfig ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf-
make u-boot-nand.gph ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf-
And in bare board, i was able to load the u-boot for first time and it booted up properly,
U-Boot 2015.07-00080-g68db1b0-dirty (Mar 04 2016 - 10:55:28 +0530) CPU: 66AK2Hx SR2.0 I2C: ready DRAM: DDR3 PLL (PLL2) Setup ... DDR3 PLL Setup complete, DDR3A clock now running at 400MHz.

After customizing the u-boot, i followed up nand erase procedure and flashed u-boot in in NAND,
nand erase.part bootloader; nand write ${addr_uboot} bootloader ${filesize}
When i restarted the board, i could see only old uboot and not the updated uboot.. Verified with the time and date .
To cross check this, i loaded the uboot through CCS and executed,
I could get the updated u-boot prompt,
CPU: 66AK2Hx SR2.0 I2C: ready DRAM: DDR3 PLL (PLL2) Setup ... DDR3 PLL Setup complete, DDR3A clock now running at 400MHz.

But when the same uboot when flashed in NAND ,it boots with old uboot image and not with updated uboot.
I suspect, uboot is booting from location which is not erased.
How to check it.
Please guide to solve this issue.
