Bootloader help

[thetech]

Trying to get rockbox running on a kenwood HD20GA7.
I also have a gigabeat F.

Both players are very similiar in both hardware and software.

The .DAT bootloader that ships with both players is the same size.

I have only gone so far as trying the gigabeat rockbox bootloader on the kenwood. Of course it does not boot. I figure this is due to the bootloader path being in a different location than the gigabeat

How can I modify the gigabeat rockbox bootloader to boot the kenwood?

I'll sort out button differences, etc once I get it booting.

Thanks

Besides both having bootloaders that are the same size with a .dat extension, what do you know about the player? You can't just give it the file custom designed for a different player and have any reason to expect it to work.

Both are s3c2440.
They use the same LCD and DAC.
Toshiba and Kenwood use same linux source.

I am fairly certain the gigabeat bootloader can be booted on the Kenwood if appropriate changes are made.

I have no experience porting or compiling rockbox. I can't imagine anyone else being interested in doing this as the kenwood player is rare.

If appropriate changes are made, the Rockbox bootloader can be booted on ANY player. But it requires some very specific knowledge about the low level bits of the player.

Guess I'll do it the hard way.

There is no easy way.
