Hi Jaap Jan, Thanks for your reply. What do you mean by 'works out of the box with denx'? I see the code you referred to but not sure how to use it. I still have some concerns. Like,
1. How can i initially store the image into flash? My flash chip is on the board. 2. How can i boot linux from flash? 3. Currently i have a 32MB SDRAM along with flash. I have tools to download linux image into SDRAM. Even if i go with MTD/JFFS, my concern is unless linux runs flash can not be accessed and vice versa. 4. Lets say, i download linux into a safe place in SDRAM, boot it and then access flash thru MTD/JFFS and store linux image into flash. Even in this case, what all i need to take care of for making my flash a boot device. Any detailed documentation is appreciated.
