u-boot-0.3.0 + Linux boot failed on walnut

[digitalRNA]

Hello,

Now I am trying to boot Linux using u-boot-0.3.0 not openbios on walnut.
But it failed.
It looks failed around timer initialization on vmlinux.
But in the case of openbios, the Linux can boot.
Are there any information about this issue?
