Cowon D2
store88:
My D2's battery in charge, test wait 3 hours
I don't know where to get a datasheet for that specific NAND chip
And I did the following step:
compile in "D2 and Bootloader" style,
But copy the 7z file from http://download.rockbox.org/daily/cowond2/rockbox-cowond2.zip, uncompress it to D2 root directory.
next time, I'll try add this instead of nandinfo I added before.

when I patch the bootloader to d2N.bin(version 2.59)
It displays
--- Quote ---original firmware entry point: 0x2000006c
New entry point: 0x203204fc
--- End quote ---
Should rockbox.d2 be recompiled, If bootloader is changed?
--------------------------
Now I can see the rockbox logo now
and the infomation in the lcd is
--- Quote ---Ata
mount
File not found

the rockbox I tested is from the daily build
and my D2 cannot be turned off now :(
Noobtaculus:
I'm sorry this is such a noob question, how do I compile the bootloader to patch the Cowon firmware? Or can someone direct/send me to a pre-patched set of files? And how well is 2.59 working with this RB? Thanks in advance.

@Noobtaculus
you can download from ftp://andiators.homeip.net/
And there is a "how to install.txt" in that server.
It's likely most people can success, except me.
@all
Now I copy the rockbox.d2 out of .rockbox directory
My D2 can find the rockbox.d2 now.
A new error comes:
--- Quote ---ATA
mount
Length: 778A8
Checksum: 0
Model name:
Loading rockbox.d2
Sum: 1FFFEE7
Bad checksum
--- End quote ---
this is release 3.1
And I had tried recent daily buid too
my D2 can't load firmware from /.rockbox/rockbox.d2
but /rockbox.d2 is ok
and the Sum is 18
but in the config-cowond2.h
--- Quote ---/* Offset ( in the firmware file's header ) to the file CRC */
#define FIRMWARE_OFFSET_FILE_CRC 0

With recent build, be sure to update your bootload too. I just had the Checksum error after an update on my working copy, it was solved by reinstalling the bootloader.

I updated my bootloader again with the recent build.
and rebuilt add following into nand_id.c

but lcd still displays:
Checksum: 0
Sum: 18
and still can't find rockbox.d2 from .rockbox/ directory.
only can recognize /rockbox.d2
And, can anyone build the bootloader for me
add the new nand_id
maybe there was something wrong that I didn't know occurs while I
built the bootloader.
