[Yaffs-archive] some questions to use the Yaffs

[gjx]

hello,yaffs

=09Our development board is PB1000,our system's Brief Details: 
cpu-AU1000/AU1100,Operation System-Monta Vista Linux(hardhat=
 linux),256M NAND Flash(SumSung),256K/1M NOR flash(AMD),=
 bootloader-YAMON.
  
   We want to use the YAFFS, do we need to write the MTD driver=
 for my nand flash? If we have to do so,please give me some=
 references and some notes.

   I found that the balloon's brief=
 details(http://www.toby-churchill.org/):1MB NOR Flash , 32MB=
 NAND flash , Linux 2.4.19-rmk4-tcl2 , yaffs filesystem ,=
 Bootldr. 
(1)Is the bootloader stored in the 1MB NOR Flash?  And Are=
 OS(Linux 2.4.19-rmk4-tcl2) and root filesystem(yaffs) stored in=
 the 32MB NAND Flash? 
(2)If it is right above, I think the Bootldr should be able to=
 identify the YAFFS, and the kernel of the OS can subsequently be=
 read from the NAND(i.e. yaffs) to the RAM.  is't true?
(3)if it is true above, how to modify the bootloader to realize=
 the idea? 
(4)Can you send the relevant document of the modification of the=
 Bootldr for using the yaffs?
    if you can't understand,please send to me, i will describe it=
 in detail.   thanks very much!
