Re: Problem with x50v serial console

Fisherss, do you still know what you've changed with the haret program
exactly? Maybe we can sync that with the latest version, or with the
version with the cool penguin :-)
And for X50V, we should use the same version, right? And the same default.txt?

And another question about the kernel: Did you have to change anything
with the kernel source? For X50v, I think Richard has changed at least
the vsfb driver, is that right? Do the notes from you about building a
new kernel still last?
