Introduction

The GSoC 2009 has officially started on May 23rd and I haven`t made any update since May 18th when I stated my hardware lacking. I finally got a functional development environment by around June 2nd(last week) when my backup LPC chip arrived to Cuiabá(my living town).

It`s a little difficult to buy some hardwares(specially some old age ones) here in my city. The only hardware I could purchase here was the processor and DDR400 memory. I had to wait about 7-10 days for the other hardwares. I also had funds problems(I didn`t have the whole money to buy everything at once). Now the PCI USB expansion card is the only lacking hardware, but I don`t think it`s blocking the project but I can buy it in the coming days.

Tasks and Code

Few things to point:

  • Option Rom Assembly Link Code:
    I`m using the source code from Darmawan, Jason has also used that. Stefan has mentioned some licensing issues, he said he would ask Darmawan to register his source code to some coreboot compatible license since we may want vendors to include the option ROM in their motherboards. Stefan also said about using his option ROM source code instead. With that I started to work with Stefan`s source code to make it work(I couldn`t run it). Jason may take it over since he`s responsible to the option ROM initialization code and assembly bits.
  • libpayload linking:
    The makefile I`ve copied/modified from FILO source base is theoretically linking the option ROM to libpayload but I couln`t call any function from libpayload yet. I`ve not spent too much time on it, I can fix it in the next days. Jason has faced this problem as well. I used FILO to complete the tests I wanted to do with libpayload API since it`s been successfully linked to libpayload.
  • bootable USB preparation:
    I worked few ours last week to prepare a bootable USB stick.

Comunication and Repos

I`ll keep posting the updates on my blog, I have a dedicated category to that, you can follow that for updates, I`ll not stop mailing all the mentors but a simple mail stating an update will be sent every week.

I would like to remember you that we(Jason and I) have used repositories on my server for hosting the source code we produce.

Update: Jason has just told me he`s rewriting the ldscript we`ve got from Darmawan. So we`ll not need to care about the licensing issues any more.
