booting DVEVM from NAND flash

Started by rajeshg March 26, 2008
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

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.

Regards,
Stefan
