Title: firmware_fm.bin 2.3 file size
Post by: elmanu on November 09, 2004, 06:22:52 AM
Hi everybody,

I successfully flashed my FM with the 2.2 version a few weeks ago.
Now I want to flash with the 2.3, but I noticed that the new firmware_fm.bin file is only 77 Ko.
The 2.2 one was 189,7 Ko
How can you put more features in a smaller file ?
Do I have a problem ? bad uncopress or something ?

Thanks for your answer

You are not the first one to not understand the flashing process. We need to address this documentation issue somehow.

I have a few questions for you:

Which documentation did you use to find out how to flash Rockbox?

What did that documentation say about how to update the already flashed Rockbox to a newer version?

Whow, what a fast answer !

First of all, I think I did perfectly understand the documentation, because I already flashed the 2.2 version !
Anyway, I did'nt noticed there was a chapter about "how to update the already flashed Rockbox to a newer version"
I will read it immediately and tell you if I understood.

Thanks a lot for your answer.

Hi again !

OK, I read the following documentation : http://www.rockbox.org/twiki/bin/view/Main/BlindFlashing#5_Add_Update_Rockbox_in_Flash_me

20 seconds after, I had my new version flashed !
Whow, it's VERY fast to browse in the directories !! Incredibly faster than 2.2 !!

Thanks for this great work.

Me again,

even if my personal problem is solved, it doesn't explain why the 2.3 bin file is smaller than the 2.2.
Let me try to resume what I understood :
-the 2.3 program is on the ajbrec.ajz file. The .bin file contain only some parts to allow to flash the content of the ajbrec.ajz in the ROM. Right ?

Thanks to confirm (or explain if I'm completely wrong, I'm just curious)

The 2.2 version of the firmware_xxx bin file contained the 2.2 firmware as well as the boot loader and the original Archos firmware.

This has now changed, and the firmware_xxx file only contains the boot loader and the original Archos firmware. After the initial flashing, the only thing that has happened is that the flash is *prepared* for flashing Rockbox. It still starts the original firmware, since Rockbox is not yet in flash.

To put Rockbox in the flash as well, you do the same as you do to update the flash, i.e play the /.rockbox/rockbox.ucl file.
