Hi I am trying to boot my TI TMS320DM6446 DVEVM(Evaluation Module) board through NAND flash,followed the steps as per document spraaa0 from Texas Instruments(TI). when I tried the step 2.2 i.e. loading the flashwriter_nand.out image into nand flash using Code Composer Studio 3.2 it gives the error as as follows Trouble Writing Memory Block at 0x88019428 on Page 0 of Length 0x328: Error 0xA0002020/-173 Error during: Execution, Control, Error generated by SD scan controller module Sequence ID: 16 Error Code: -173 Error Class: 0xA0002020 i restart the code composer studio and try to load the flashwriter_nand.out image again into the flash it gives the following the error data verification failed at address 0x88019100 please verify the target memory and memory map can anyone give me idea why this is happening and how i can resolve it Regards Rajesh G

Moin, NAND flash may contain defective blocks and it is your responsibility to mark and replace those. If a certain location of the NAND refuses to be programmed, add it to your list of bad blocks and never touch again. I don't know about the TMS or the document you refer to, but it should cover cases of defective blocks in NAND. In case you are developing for a product that is intended for mass production, consider yourself lucky that your development system has defective NAND already, otherwise this malfunction would have appeared during production, possible causing much more trouble than you have now.
