As a read from ARM_Subsystem.pdf , "The RBL does not support booting from 4K nand pages". Is that true? Couldn't I support, this flash for dm355 Cheers From: Gorwood, Steve [mailto:[email protected]] Sent: Tuesday, January 13, 2009 6:25 PM To: canibek sagin; [email protected] Subject: RE: UBL and U-Boot for 29F16G08DAA The UBL and NAND programmer in the PSP_01_20 package reads the device id from the NAND device and uses an internal lookup to decode a device id of 0xD3 as a MT29F16G08QAA NAND device. The MT29F16G08QAA and MT29F16G08DAA both use 0xD3; but have different device charactoristics. In particular, the MT29F16G08QAA has a 2K page size and the MT29F16G08DAA has a 4K page size. This will probably work with the current silicon and software stack (although you would only be using the first half of each page), but the programmed NAND device would not be compatible with future spins of the device and software stack which correctly identify the page size.

This sample nandflash is 29F16G08DAA. We want to use it, so I tried loading ubl and u-boot by xds510 to DAA . After reset it behaves like QAA nand flash. After reset it says "This is MT29F16G08QAA NandFlash." UBL and U-Boot flashing process looks correct but I couldn't be sure because of that message. How can I load UBL and U-Boot to 29F16G08DAA for dm355. Best Regards
