Dinh - my workflow is exactly as yours is above. I've used several toolchains - always the same result. The first de0_nano_soc board I bought has no problem booting from the factory supplied image: SPL: U-Boot SPL 2013.01.01 (Dec 29 2014 - 15:29:15) Image: U-Boot 2013.01.01 (Dec 30 2014 - 12:07:34) and it even works with some USB sticks. But if I build a new SPL/image with workflow above using v2016.03 (git clone git://git.denx.de/u-boot.git u-boot/ or git clone http://git.denx.de/u-boot.git u-boot/) then I get the intermittent failing memory calibration and no USB (dwc_otg_core_host_init: Timeout!...) On my sockit board the memory calibration fails every time. So I ordered and received a _second_ de0_nano_soc board. The same SPL/image that was intermittently failing on the first board works on the second board. I have not seen it fail after 20 reboots. Unfortunately, USB behaves the same (dwc_otg_core_host_init: Timeout!...) Not sure what that means... marginal boards from Terasic? Calibration tests/parameters too stringent? --George
