Yes, I'm aware of that. I think having the IBE bit set in u-boot has advantages nevertheless. I think the kernel can't enable the bit sufficiently early if its compiled in thumb-mode itself (CONFIG_THUMB2_KERNEL). So I suggest to enable the IBE bit in the kernel (that part is already done) *and* in u-boot. -- Sebastian -------------- next part -------------- A non-text attachment was scrubbed...
