Re: [coreboot] How to best add new boards derived from existing board?

Sure, but in this case the boards were copied and my question is, how these can be reviewed easily. Reducing 4500 line differences to less than 1000 would certainly help. Thanks, Paul

The variables defined there are used for the build process and should point to the cross compiler. If you want to use it manually, i386-elf- is the typical prefix we use, so the compiler is i386-elf-gcc. Patrick

Calling the cross compiler

by Marcello Stanisci

Dear mailing list, I ask you how can I call the cross compiler for architecture X to build coreboot+coreinfo for qemu. I built successfully the cross compiler but the procedure says only where the binaries of xgcc are located but nothing about calling them. What is the standard way to do it? Regards, ms

question about dsdt table in coreboot

by jstkf2012＠126.com

Dear Maillinglist, I have question about dsdt table in coreboot. How can we add dsdt table into coreboot? In acpi_tables.c,we will see that： dsdt = (acpi_header_t *) current; memcpy(dsdt, &AmlCode, sizeof(acpi_header_t)); current += dsdt->length; memcpy(dsdt, &AmlCode, dsdt->length); but how can we get the address of Amlcode。 Thanks TankTang From: coreboot-request Date: 2013-09-28 18:00 To: coreboot Subject: coreboot Digest, Vol 103, Issue 22 Send coreboot mailing list submissions to coreboot(a)coreboot.org To subscribe or unsubscribe via the World Wide Web, visit http://www.coreboot.org/mailman/listinfo/coreboot or, via email, send a message with subject or body 'help' to coreboot-request(a)coreboot.org You can reach the person managing the list at coreboot-owner(a)coreboot.org When replying, please edit your Subject line so it is more specific than "Re: Contents of coreboot digest..."

It seems the Acer C7 from Google full fit my *hardware* requirements. But I am not planning to use Google Chrome os instead I need to run Debian 7 on it. I like to play with GNU/Linux on embeded devices like the ones supported with OpenWRT or even the Raspberry PI, usually all they come with firmware files or disk images ready to be loaded and let me get them up and running quickly, I am not a hardware geek guy, so I don't want to spend too much time dealing with the internal of the Acer C7 Chromebook in order to load GNU/Linux on it. So, this is what i want to do: * Completely remove all the google OS stuff. * I don't need to run windows, so I don't care is the replacement firmware will not allow me to install such a crappy system in the future even if I sell the device later. * I want to run something 100% free since it power up, for those who have this laptop can you tell me if the wifi drivers, camera, network adapter and so on are 100% free ? * There is a web page which describe the procedure in a single page ?

Even coreboot on Chromebooks is not entirely "free", as there are several closed Intel binaries needed. Not sure is any non-free firmware needed for the Atheros card but it should be pretty open. > * There is a web page which describe the procedure in a single page ? > I > know the coreboot website have a lot of information, but time is a > constraint, so there is a step by step instructions webpage with all > the > files, requirement and procedures to free the Acer C7 laptop and then > be > able to install a GNU distribution on it ? http://johnlewis.ie/compiling-your-own-coreboot-firmware-for-the-samsung-se… and http://www.coreboot.org/Chromebooks/550_Chromebook_Build_HOWTO but the latter is slightly out of date. Just change the vendor and product. The same guy that bricked below followed the same instructions himself and got a straight SeaBIOS payload that worked. > * I found some prebuilt images at > http://johnlewis.ie/pre-built-coreboot-firmware-for-chromebooks/ > there > are some official or daily rom firmware from the coreboot project in > a > similar way like the ones produced by the OpenWRT people ? No. That's why I created those. BTW, don't build in USB dongle support at the moment unless you can de-brick - one of the guys commenting on my site bricked his when he compiled it in.

We collect tools for BIOS image unpacking in the bios_extract repository (git clone http://review.coreboot.org/bios_extract.git), there's also j-bios (http://www.jakobheinemann.de/j-bios.html), and 7-zip can unpack some UEFI Fvs. For coreboot, cbfstool's extract can be used. Hope this helps, Patrick
