I would like to build the latest freescale open source u-boot code 2014.10 on my imx 25 3stack board for using the verified boot options enabled (signed u-boot). I am aware that v2009.08 is the latest official release supported. However I need to know if 2014.10 is supported. I tried to flash another newer version after 2009.08 into NAND and boot from NAND. However, the board didn't boot up and I couldn't see any logs in minicom. I assume the u-boot failed to boot up on board. I tried to flash the board using ATK and I got a message that "NAND failed to initialise". Kindly let me know what can be done. Also please suggest what needs to be done in order to use the latest u-boot for imx 25.
