C213 write protect

[Gabriel Brangers]

Anyone Keen to where the write protect screw is located on the Asus C213?

Gabe,

If that's 'reef' (ASUS Chromebook C213NA, Acer Chromebook Spin 11 (R751T / CP511)) then I think it's one of the newer devices that support 'Closed Case Debugging' so there is no physical write-protect screw.  You can see which devices use it by looking at the last column on the table for 'Developer Information for Chrome OS Devices'.

On those devices, like my Eve, you'll need to use a 'SuzyQable' and 'Beagle Term' to access the 'wp' setting and others.

From what I know there's an easier way to do that besides connecting a SuzyQ in that configuration. In theory you shouldn't need a SuzyQ at all to disable write protect.

I'll let Vadim and Randall fill in the details.

I think you can pull the back off and disconnect the battery on some models but I'm not sure how easy that is to do on the C213.

Disconnecting the battery is quite easy on C213, while it's disconnected, the write protect should be disabled. This is probably the easiest approach.

Otherwise you could wait a couple weeks and the production release of CCD should be available on dev channel along with documentation on how to open and disable write protect.

Nick,

• What dev channel version were you referring to above?
• Any updates on this documentation yet?

I've seen what I think are some new links on 'Closed Case Debugging (CCD)' -

• https://chromium.googlesource.com/chromiumos/platform/ec/+/master/board/servo_micro/ccd.md
• https://www.chromium.org/chromium-os/ccd/951-00273-01_20180607_suzyqable_SCH_1.pdf?attredirects=0&d=1

But I haven't stumbled across the documentation on how to open and disable write protect yet.

Updated docs on accessing and using the debug and gadget-mode interfaces would be very welcome.

 

Thanx,

~Denny
