By the looks of it that's pretty much what I've done and I don't see any differences that could cause it to fail.

I'll have a look at that, thanks for the pointer. Side note: the git repo URLs shown by your gitweb are wrong — they contain two slashes after the domain, and aren't clonable (but taking out the extra slash fixes it).

[coreboot] (depthcharge, vboot) Difficulties booting on Chromebook
Hi all, I've been following the instructions for getting Debian running on an Asus C201 Chromebook[1]. This has been going well, mostly, except that when I try to actually boot it (power on and press Ctrl-U) I am greeted by a loud and low-pitched beep and not much else. Any ideas as to what I may be missing? Relevant stuff: # crossystem | grep dev_boot dev_boot_usb = 1 # Enable developer mode boot from USB/SD (writable) dev_boot_legacy= 0 # Enable developer mode boot Legacy OSes (writable) dev_boot_signed_only = 0 # Enable developer mode boot only from official kernels (writable) I've uploaded an image of the SD card resulting from the instructions (208M, 2G uncompressed) at [2].
