#134: flashrom crashes acer aspire one laptop -----------------------------------------------------------+---------------- Reporter: Timo Juhani Lindfors <timo.lindfors@…> | Owner: somebody Type: defect | Status: new Priority: minor | Milestone: Component: flashrom | Version: v2 Keywords: aspire laptop | Dependencies: Patchstatus: there is no patch | -----------------------------------------------------------+---------------- I ran the "flashrom" command on my acer aspire one laptop. The display turned black and the system did not respond to even sysrq after that. (Fortunately the system boots after powercycling.)

This is debian stable with flashrom package that has version "0.0+r3397-1".

Service manual says that this laptop has WPCE775L EC that talks LPC v1.0 and that the flash chips are behind it. Also on IRC I was adviced that

< carldani> lindi-: can you please add a small statement to the ticket which mentions the exact EC and that it translates LPC to SPI.

I looked for docs on the EC but found nothing. Until someone finds documentation for it, there's really nothing we can do. Please reopen when there is more information!

Not that it helps but the nuvoton website says: "The WPCE775x family is pin-to-pin compatible drop-in replacement to the WPC876x family of devices, requiring only minor firmware changes."

Hi, can you please tell us (just for reference) which Acer Aspire One model this is exactly? It seems there are multiple laptops/netbooks that are called Aspire One.

(we want to fix the string in the list of non-supported laptops at http://www.coreboot.org/Flashrom#Supported_laptops.2Fnotebooks)

Thanks!

Comment:

Could you please try to run superiotool again? The latest revision (r5667) has support for your EC and should work (unless the laptop manufacturer reconfigured the EC to listen on another address).

Besides that, flashrom (0.9.2 or later) should detect that it is running on a laptop and abort immediately before anything bad can happen. We plan to whitelist some laptops eventually, but for now we're going the safe route. If flashrom does not detect your laptop as laptop, please file a new bug at http://www.flashrom.org/trac/flashrom/newticket

I have reopened this ticket for now to keep it active until we know if superiotool works for you.

Hmm, should tracker.coreboot.org sent me email about all these comments? I can't find any of them from my procmail.log.
