Hey everyone!
The bootstrap-mmc target is now finally available! What this means is that you can follow all instructions in [1]

[GSoC 2014 : ARM Port] Week #7

Hey everyone!
Just like week 6, this is another short update.

I’ve been working on creating a bootstrap-mmc target for the build system. The current issues I’m facing are
  1. Downloading MLO and u-boot fails and thus build fails since jam doesn’t know how to create those targets otherwise. I managed to fix this but apparently, the fix breaks the current build system so I need to modify the fix such that it doesn’t break the build system.
  2. Copying the bootstrap image as the second partition of the MMC image. I planned to use dd since it works fine and probably works fine on Linux and BSDs but dd requires a size to be specified, which is slightly tricky to compute in jam. The obvious solution of using cat doesn’t seem to work - the resultant size of MMC is much higher than expected.

I hope to add the bootstrap-mmc target for jam within this week which would make it much easier for anyone to build the image.

Hey everyone!
Here’s an update on week 6(a relatively short one so no TL;DR :) ).

I managed to fix the bootable SD card image generation script that I created last week to use mtools and thus eliminate the need for losetup and root permissions. The script is available in a Github[1] repository

Meanwhile, I’ve also been working on adding a bootstrap-mmc target to Jam. Right now, the target generates the haiku_loader_nbsd.ub successfully but fails because it doesn’t know how to generate MLO and u-boot. I have not figured out why it doesn’t know how to make targets MLO and u-boot. Hopefully, I’ll fix that up in a few days.

[GSoC 2014: ARM port] Week #5

Hey everyone!
Here’s an update on week #5.

TL;DR - I created a bootable SD card image that boots up when emulating BeagleBoard-xM in qemu. Control is passed to haiku_loader, which then crashes. A link to the necessary u-boot files and an sh compatible shell script(that generates the SD card image) is provided at the end.

Update: There's a better script that does not require losetup/root permissions listed in update for week #6.

Hey everyone!

Here’s an update on progress during week #3. Sorry about the delay - exams have started for me.

TL;DR - I didn’t succeed in creating the bootable SD card image since I’ve been preparing for exams. There are some instructions and probably next steps in this direction listed here. More work on this will be done after exams.

Hey everyone! Here’s an update on what’s happened so far.

TL;DR - PulkoMandy managed to build the bootstrap image and kallisti5 has made some progress in running the image on the qemu. This is a significant progress since bootstrap image build never succeeded but not quite usable on BBB. I’ve not made much significant contribution. Instructions for building the bootstrap image are at the end. Otherwise, read on.

Hello everyone!
Most of you know that 4 students have been chosen to work with Haiku during the Google Summer of Code(GSoC) 2014. My name is Arvind and I am one of the 4 students(yaay!). I will be improving the ARM port and hopefully make significant progress.
