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?
That probably means that your boot medium was not setup correctly. Perhaps the Debian instructions are either incorrect or incomplete.
Do you know of any "known-to-work" instructions for setting up a non-chrome OS boot medium that I could compare my setup to or try using instead? Or a way to get more helpful information than a beep from depthcharge?
I have a cros-medium-setup script that does that: https://git.code.paulk.fr/gitweb/?p=libettereboot.git;a=blob;f=projects/cros...
You could try to run the paritions action and then cat a known good kernel image to the first partition. Alternatively, you can use my whole build system: http://git.code.paulk.fr/gitweb/?p=libettereboot.git;a=summary to build a cros kernel and install it to the storage: ./libreboot download linux-cros ./libreboot cook linux-cros veyron ./libreboot cook cros-scripts cd install/cros-scripts/ ./cros-kernel-prepare pack ../linux-cros-veyron usb ./cros-medium-setup partitions /dev/sdfoo ./cros-medium-setup kernel /dev/sdfoo ../linux-cros-veyron usb
That will however take a while to complete. I'm not providing binary releases at this point (or any official documentation, really).
Maybe reading these scripts can help you figure out what is going wrong with your setup.
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].
