vinodh
Hi,
   I installed wince5 in mini2440 kit via NOR flash after finishing this
installation i can see the OS is getting run in mini2440.after that i
switched of the mini kit then i select NAND flash, This time the OS is not
getting run but i can see the wince logo image is keep on loading..

My question is; 
1. How can i install the OS in NAND flash?
2. if i can see the boot logo image in NAND flash then why the OS is not
getting run?
3. Give the exact file name and the file format of Wince5.0 to install the
OS in NAND flash?
4. while using this command"bon part 0 320k 2368k",the memory size is get
divided in to three part and each part has the different size of memory. in
that last partition says "badblock=2"..Do u thing becaz of this NAND get
booting problem?
5. We are using this command for partitioning but what the meaning of this
command "bon part 0 320k 2368k"?
6. Give the exact steps to install wince5 image in mini2440?
