kernel and bootloader sources, toolchains #1

Closed rileyx closed 11 years ago

rileyx commented 11 years ago

Please provide the sources for kernel 3.0.31 stamped may 7, 2013 @ 17:11:07 and the associated toolchain, build scripts etc.

I would also appreciate the sources and toolchain for the Arc bootloader. If there is more than one bootloader "in the wild" please provide instructions for determining which version is in a particular Arc as well.

Thanks.

Hi,

The toolchain is CodeSourcery 2010q1 and there is a build script in kernel.tgz package that shows you how to build the kernel. Pass in "zeus" as the first parameter on the command line.

The bootloader isn't open source.

I will update the kernel tarball shortly so that it lines up with the latest May 7 release.

Thanks for the kernel sources. Is there more than one bootloader in use? When I connect to my arc with fastboot, I can do this, which looks like I am talking to uboot: (which is GPL afaik)

fastboot getvar version version: 0.5 finished. total time: 0.004s

fastboot getvar version-bootloader version-bootloader: ZEUSXX03 finished. total time: 0.004s

fastboot getvar secure secure: HS finished. total time: 0.005s

fastboot getvar product product: zeus finished. total time: 0.003s

fastboot getvar serialno serialno: xxxxxxxxxxxxx finished. total time: 0.008s

Thanks.

Hi,

There are two bootloaders in play here - see the OMAP reference design. We were using U-Boot as the secondary bootloader but it was to have been switched out for something properietary.

Let me follow up internally. It may take some time for a response.

rileyx commented 11 years ago

I understand. Thanks for getting back so quickly. When you are checking out whether or not the arc is using uboot, could you also find out if the first stage boot-loader is x-loader? If so, could you please provide those sources as well?

Thanks

rileyx commented 11 years ago

sorry about the close

gtalusan commented 11 years ago

The first stage bootloader is x-loader. I've placed the source code online.

Please keep in mind that the binaries are signed.

rileyx commented 11 years ago

Will do. Thanks.

rileyx commented 11 years ago

Any progress with the uboot question? Thanks.

gtalusan commented 11 years ago

Wheels are in motion.

rileyx commented 11 years ago

Uhoh... I hope that doesn't mean there is uncertainty about the code that was used to compile the boot-loader. It's never good when that happens.

Regardless, thanks for your efforts.

rileyx commented 11 years ago

Are the wheels still in motion? How much longer do you think this will take?

gtalusan commented 11 years ago

Yes. Sit tight.
