Dear all,
I am quite new to uboot and I am experimenting it on a iMX28 EVK board (rev. D).
I am building the uboot (2014.07 version) by means of buildroot (version 2014.08) and I am using the standard mxs-bootlet package provided by buildroot.
When trying to boot the EVK, it hangs after DRAM initialization as shown below.
The EVK itself seems ok since barebox (also built with buildroot) can successfully starts up.
I have read that such problem has been seem on iMX28 EVK rev A but I am not aware of any DDR related issue on the iMX28 EVK rev D board.
Would anyone have already seen such issue and know if some patches are required in uboot?
Thanks in advance for any help or suggestion
Best regards
Adrien
