 Posted: Sun Sep 05, 2010 2:08 pm Post subject: Crossdev MIPS, mips-headers deleted [solved] |
 |
|
Hi everybody,
I'm trying to set up a crossdev environemnt for compiling programs for the MIPS architecture.
(Got a media player sporting something reported as MIPS 24K V7.8 CPU)
But crossdev fails during stage 1:
| Code: |
# crossdev -S -s1 --target mips-r3000-linux-gnu
--------------------------------------------------------------------------------------------------------------------------------------------------
* crossdev version: 20100620
* Host Portage ARCH: x86
* Target Portage ARCH: mips
* Target System: mips-r3000-linux-gnu
* Stage: 1 (C compiler only)
* binutils: binutils-[stable]
* gcc: gcc-[stable]
* PORTDIR_OVERLAY: /usr/local/portage
* PORT_LOGDIR: /var/log/portage
* PKGDIR: /usr/portage/packages/cross/mips-r3000-linux-gnu
* PORTAGE_TMPDIR: /var/tmp/cross/mips-r3000-linux-gnu
_ - ~ - _ - ~ - _ - ~ - _ - ~ - _ - ~ - _ - ~ - _ - ~ - _ - ~ - _ - ~ - _ - ~ - _ - ~ - _ - ~ -
* Forcing the latest versions of {binutils,gcc}-config/gnuconfig ... [ ok ]
* Log: /var/log/portage/cross-mips-r3000-linux-gnu-binutils.log
* Emerging cross-binutils ... [ ok ]
* Log: /var/log/portage/cross-mips-r3000-linux-gnu-linux-headers-quick.log
* Emerging cross-linux-headers-quick ... [ ok ]
* Log: /var/log/portage/cross-mips-r3000-linux-gnu-glibc-headers.log
* Emerging cross-glibc-headers ...
* glibc failed :(
* If you file a bug, please attach the following logfiles:
* /var/log/portage/cross-mips-r3000-linux-gnu-info.log
* /var/log/portage/cross-mips-r3000-linux-gnu-glibc-headers.log
|
And checking the latter logfile, the problem is:
| Code: |
emerge: there are no ebuilds to satisfy ">=cross-mips-r3000-linux-gnu/mips-headers-2.6.10".
|
Checking http://sources.gentoo.org/cgi-bin/viewvc.cgi/gentoo-x86/sys-kernel/mips-headers/ shows there are no headers any more. They have all been deleted. Which is confirmed by the log for one of the deleted packages:
| Code: |
Revision 1.3
Wed Dec 17 05:45:47 2008 UTC (20 months, 2 weeks ago) by kumba
Branch: MAIN
CVS Tags: HEAD
Changes since 1.2: +1 -1 lines
FILE REMOVED
mips-headers is quite dead, so remove it from portage (hasn't been updated in over a year).
http://sources.gentoo.org/cgi-bin/viewvc.cgi/gentoo-x86/sys-kernel/mips-headers/
|
What this seems to mean to me is that I can't use gentoo crossdev for mips?
And what I don't understand is why the packages has to be deleted. Even though they're not maintained any more, they are still useful?
If I can't use gentoo crossdev, does anyone have a hint how to set up a cross developing environment for the mips architecture?

This should work:
crossdev -t mips -v -b --b 2.20.1-r1 --g 4.4.4-r1 --k 2.6.27-r2 --l 2.10.1-r1 --without-headers
Also, are you sure you need big-endian? If not, use "-t mipsel" |

Thanks, will try that tomorrow.
What I need is to be able to create files like this:
| Code: |
$ readelf -h busybox
ELF Header:
Magic: 7f 45 4c 46 01 01 01 00 00 00 00 00 00 00 00 00
Class: ELF32
Data: 2's complement, little endian
Version: 1 (current)
OS/ABI: UNIX - System V
ABI Version: 0
Type: EXEC (Executable file)
Machine: MIPS R3000
Version: 0x1
…

| then use "-t mipsel" to create little-endian binaries by default. |

Most excellent! I've managed to compile a simple "hello world", and execute it on the media player!
Thanks a lot for the help! |

My pleasure.
If I may ask: which device? I'm always on the lookout for new MIPS toys! |

What I liked about it is that it is fan less, can do 1080p on hdmi and has s/pdif. I have not really used is as intended, instead I'd like to turn it into a pure music player.
There is also a version called TrekStor MovieStation Antarius, it only does 1080i, but has wifi. |

|

Hi there,
Have read up on the CPU and board but not found out what the video processor is.
Does anyone know what it is?
Thanks, and thanks for all the work you people have done on this device! I'm buying one tomorrow. It looks like a very nice and small Linux platform to hack on.

-For Future Reference
The Realtek Mips 24k (Code-name Venus) is a SoC, the GPU is on the chip, it's a "PowerVR" designed by Imagination Technologies (formerly VideoLogic). However over 20 companies have authorization to reproduce it & use it. Realtek chips such as this one are extremely common among media players .. many of them use a SoC (realtek) mips /w PowerVR gpu. I couldn't even begin to count the different generic brands/models of media players that use this type of chip.. You'll find the source code to these players closed & unavailable.. especially when it comes to kernel/modules & the video player itself.. Most use the the same software just slightly different versions from chip to chip with a different GUI. The GUI being a group of scripts/xml/png files ran by the video player engine. The video player engine often has the name "DvdPlayer". It does everything from playing video to audio and even connects the player to wi-fi.. along with a slew of other tasks on the newer 1186 chips. I've found most players based on the "DvdPlayer" engine are highly insecure.. and caution should be used when deployed on secure networks. |
