Hi fellow CB5-311 users,
so now I have a PinebookPro, and the
trouble with u-boot continues...
First thank you, fedup, for posting instructions again on how you compile a kernel! Because I'd still like to see what this Chromebook can do I followed it through, just booted into Linux version 5.4.47 - but still xvinfo -> no adaptors present.
Maybe it is because I'm doing something different
after your step 5? I basically repeated the procedure I established about two years ago:
$this->bbcode_second_pass_code('', ' mkimage -f nyan-big-fit.cfg nyan-big-kernel
vbutil_kernel --version 1 --arch arm --keyblock kernel.keyblock --signprivate kernel_data_key.vbprivk --vmlinuz nyan-big-kernel --bootloader dummy.txt --pack kernel.kpart --config cmdline')
I do that in a new directory containing a nyan-big-fit.cfg that looks like
this example. Of course I adjust paths to
tegra124-nyan-big.dtb and
zImage. Other files in that directory are cmdline, dummy.txt, kernel_data_key.vbprivk, and kernel.keyblock (all copied from somewhere long ago, but apparently working).
I then dd the resulting kernel.kpart to a kernel partition on /dev/mmcbl2, and give that one the boot priority with cgpt.
How do you proceed again, after step 5, fedup?
Sound, by the way, still seems jammed in this system. But that's probably not a kernel issue.
Anyway I will probably focus on the Pinebook from now on, and on actually getting some work done with it.
I made a new post
Comparison Acer CB5-311 vs. PinebookPro in this forum, since I believe that should not be part of this old thread.
My cubox-i, another arm computer I had mentioned here, and that never reached its full potential due to missing graphics support, apparently died today, after just about three years. It does not boot anymore. Before usb had already ceased to work, which rendered it a lot less useful. Now I'm getting a RaspberryPi as a replacement, the mainstream product with good support, similar to the Pinebook decision.
