Linux boot video – Text

Booboo says:

The video is taken from the dingoo booting a kernel configured with
framebuffer support and console on framebuffer.
The boot log text below is the dingoo booting a kernel configured without
framebuffer support and console on SERIAL port.

That said, the output in both cases is ALMOST identical. Differences:
1- In the framebuffer boot video you can see (or could see if it
wasn't that fast) the ingenic framebuffer driver initialization output
which is disabled in the serial console boot.
2- The framebuffer boot video ends at the login prompt (since there is
no keyboard as of yet, I still have to figure out how to connect it).
3- The serial console boot log goes a bit further and you can see how
I login, mount the miniSD and list the contents.

 

Uncompressing Linux… Ok, booting the kernel.

To those who aren’t keen on the long front page posts, sorry about this one …. I’m working on a better solution. Thanks to Chip for the solution!!

  1. re: the long posts -- i'm not sure how it works on blogspot, but on wordpress, there's an "insert read more" option in the text editor. i assume the same thing is there in blogspot; snoop around!

  2. Blogspot is capable of keeping posts managable, but you have to do a bit of work. Here's this exact post in a more reasonable footprint: http://chip-testblog.blogspot.com/2009/05/scroll-bar-test.html

    Here's how to do it: http://chip-testblog.blogspot.com/2009/05/how-to.html

  3. Thanks for your help, Chip! Now, you wouldn't happen to know how I could fix the Dingoo-scene logo on the top - which doesn't display properly on internet Explorer, would you? (It's OK in firefox).

  4. I'm not really an expert on these things, but it looks like IE is trying to wrap your title to the width of the background image. The blog software is expecting a full-width banner, so when you gave it a small square pic, it bugged out. The easiest way to fix it would be to make the dingoo jpg 660 pixels wide.

    The slightly harder, but probably "better" way would be to add the image manually in the header section. First go to the Page Elements editor under the Layout tab. Click edit on the header and remove the background image you already have set. Then go to the Edit HTML section and search for the line "<div id='header-wrapper'>" and add the following just after it:

    <img src="http://2.bp.blogspot.com/_mdSlICBF50M/Sa_qIggyEFI/AAAAAAAAADU/OHcn_7Lrgqo/S1600-R/dingo.jpg" alt="Dingoo's Got Moy Baby!" align="left"/>

    You might have to play around a bit with exactly which line to add it to, but it should work.

  5. Thanks again Chip! Henchforth, I dub thee, Sir Chip! Arise!
