Tegra 2 hardware adaptation

This page was created to document the port of MeeGo to Tegra 2.

This port is a work in progress and not meant for end user installation. The following details are for Tegra 2 porting effort.

This port has been enabled by the outstanding contribution of Stskeeps/Sage and others in progressing the ARM hardfp build.

Compulabs Trimslice

Irad at compulabs kindly sent me a Trimslice Pro to bring up MeeGo on, if your interested please contact me, you can find me on #meego and #meego-arm. vgrade

Using this kernel https://gitorious.org/~rmorell/trimslice-kernel/trimslice-kernel-nvidia-fixes/trees/master

TODO

• Create kickstart with later meego-ux build - DONE
• Get hardfp drivers from nVidia - DONE
• update to later kernels with PM - DONE
• try to get compulabs to seed more devices - DONE

Report on the port can be found here

Initial Bring Up

[Older stuff from vgrade]

Kernel source is available here https://github.com/martinbrook/android_kernel_advent_vega

Filesystem image and kickstart http://bug10738.openaos.org/images/tegra2/

[Newer stuff from mingwandroid]

Kernel source (2.6.36.3, forked from rebel1's VegaComb kernel with ejtagle's host_usb fixes applied) is available here https://github.com/mingwandroid/kernel_2.6.36_nvidia_base_meego (branch nv-11.2.13-m-host-usb), config is in configs/config-meego (or at http://dl.dropbox.com/u/17108768/config-meego)

Pre-built kernels (http://dl.dropbox.com/u/17108768/zImage, http://dl.dropbox.com/u/17108768/zImage-fbcon)

Kernel modules: http://dl.dropbox.com/u/17108768/meego-2.6.36.3-modules.bz2

ar6000 firmware: http://dl.dropbox.com/u/17108768/meego-ar6000-fw.bz2

Initrd: http://dl.dropbox.com/u/17108768/hardcoded-initrd-noinit.gz

Kickstart file to generate newer filesystem image: http://dl.dropbox.com/u/17108768/meego-vega.ks

Here's some instructions if anyone's interested in playing around (won't mess with your VegaComb partitions, except boot of course, unless you're already fastbooting).

install mic2 (meego-image-creator) my command line:

sudo mic-image-creator --config=meego-vega.ks --arch=armv7hl --format=raw --logfile=mic-test-tablet-1.2.0.log --run-mode=1

--run-mode=1 is needed if running on Ubuntu. This should make a disc image that ends in "-mmcblk0p.raw" dd this to your sd card, e.g.:

sudo dd bs=4096 if=meego-vega-mmcblk0p.raw of=/dev/sdb

untar the kernel modules and ar6000 fw to the root of your sd card. I use fastboot (http://dl.dropbox.com/u/15005030/fastboot_nvidia_linux.zip) with the following commandline:

fastboot -i 0x955 -c "root=/dev/mmcblk0p2 rootdelay=15 noinitrd video=tegrafb rw mem=512M@0M vmalloc=192M udev.log-priority=debug udev.children-max=1 usbcore.old_scheme_first=1 mtdparts=tegra_nand:2048K@6784K(misc),5120K@9344K(recovery),8192K@14976K(boot),155008K@23680K(system),32768K@179200K(cache),4096K@212480K(staging),306688K@217088K(userdata)" boot zImage hardcoded-initrd-noinit.gz

It should boot up to the UI and you should be able to plug in a mouse and/or keyboard. The first boot can take ages and be pretty slow. OpenGL is in software currently, so that's also not great either. If it fails to boot up, use zImage-fbcon which will output debug info to the framebuffer (X will not start with framebuffer console).

You can ssh in as well, however I couldn't get the settings program to launch (or find how to launch wifi config) so if you can't figure this out either you force a connection by adding (and changing) the following to sdcard/etc/rc.d/rc.local

SSID=MYSSID PSWD=MYPSWD STATIC_IP=SOMEIP DEF_GATEWAY=MYGATEWAY echo "ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=wheel" > /tmp/wpa_supplicant.conf wpa_passphrase $SSID $PSWD >> /tmp/wpa_supplicant.conf cp /tmp/wpa_supplicant.conf /var/log/wpa_supplicant.conf-copy sleep 10 ip link set wlan0 up sleep 10 wpa_supplicant -B -Dnl80211,wext -dd -i wlan0 -c /tmp/wpa_supplicant.conf > /var/log/wpa_supplicant.log 2>&1 sleep 5 if [ "$STATIC_IP" = "" ] ; then dhcpcd wlan0 > /var/log/dhcp-wlan0.log else ifconfig wlan0 $STATIC_IP fi sleep 5 route add default gw $DEF_GATEWAY wlan0

I wanted to use a more up to date MeeGo snapshot but for some reason (likely because I use Ubuntu instead of Fedora), mic2 refused to fetch all of the required packages.

Advent Vega Accelerated GFX with nVidia Hardfp Drivers

Now we have a 2.6.36 kernel working on Vega we need to try the Trimslice hardfp drivers on the Vega.

TODO

• Fix cursor not being displayed (an attempt is made in the new kickstart but it's not working.

• Stop the touchscreen spamming the logs.

• Overlay the nVidia Trimslice drivers onto the rootfs at http://bug10738.openaos.org/images/tegra2/

Nice to have

• Bring up uboot to allow vegecomb MeeGo dual boot (or make a simple? fake init program that will launch MeeGo kernel on HW button hold).

Entering Nvidia APX Mode

Accessing the Nvidia Recovery Mode can be accomplished by holding the - volume key and pressing power. No output will be visible but the device will show up in lsusb (on Linux) and nvflash will function.

http://forum.xda-developers.com/archive/index.php/t-827384.html

You will need the bootloader found on the tegratab wiki as the stock one found in the Nvidia package will cause strange behavior and transfer failures:

Building a MeeGo hardfp Image

These are just my lab notes I took while building the hardfp image and rely on repos on the meego OBS not on repo.meego so things are not guaranteed to work when those change or are removed. I guess hardfp repos will be on repo.meego in future.
