Summary of the Issue

I’m trying to:

  1. disable the beeping sound in case i wanna boot developer mode and shorten the wait to 2s
  2. potentially run ArchLinux from USB/uSDCard

A am able to run gbb_utility w/ sudo and I’m hoping that is sufficient

I’ve pasted the content of this command here:

Steps to Reproduce

  1. I’ve removed the restrictions w/ suzycable, all the current capabilities are Y/Always

  2. CCD caps bitmap is 0x3f_ffff

  3. flags are 0x40_0004

Expected Behavior

Ability to disable the beep, shorten the time to confirm and potentially run Arch.

Update:

I’ve managed to change the flags as recommended on this page:
* GitHub - hexdump0815/linux-mainline-on-arm-chromebooks: running linux mainline on arm chromebooks - for example: samsung xe303c12 and xe503c12 (snow and peach), acer c100, c101 and c201 (veyron speedy, minnie etc. and gru bob and kevin), medion s2013 and s2015 (veyron jaq, mighty etc.), acer cb5 311 (nyan big), lenovo n23, acer r13 (oak elm and hana), lenovo duet (kukui krane) and most probably many many more over time ... · GitHub

Works okay now.

The arch distro is not compatible with this processor
