Thanks for the pointers Jon.
I will try your suggestions and get back with the results. -- Regads , Krunal ----- Original Message ----- From: "Jon Povey " <Jon.

I find OpenOCD useful, it's JTAG software with davinci NAND drivers for both large page layouts, and config files for many davinci boards. If you do that, build the latest version from git, there have been some important patches to davinci NAND handling since the last released version 0.4.0. The source code for the OpenOCD davinci NAND driver should help you understand the layout differences. Also, I think there is some related stuff in the silicon errata for DM365. -- Jon Povey jon . povey @ racelogic .co. uk Racelogic is a limited company registered in England.
