Hi All, We got the issue, actually our DDR only supports 32bit access, 16bit and 8bit access are not supported. Is there any compiler option or any u-boot option, we need to configure so that u-boot use 32 bit access only.
Thanks in advance. Regards Shekhar Singh On Thu, Nov 1, 2018 at 7:14 PM SHEKHAR SINGH <imsinghshek...@gmail.com> wrote: > > Hi All, > > I am new to U-boot.
