Hi Everyone,
I am using TMS570LC4357,and I want drive a nand flash(K9WAG08U1B-PIB0)。 Is there an example?

Hi,
You can use the available asynchronous memory chip selects (EMIF_nCS2, 3, 4) to access the external NAND flash memory. There are some constraints to keep in mind though:
- The EMIF does not control the "Write Protect" pin on the NAND flash. This must be controlled using a general-purpose I/O pin and managed by software.
- The EMIF does not support NAND flashes that require the chip sleect to stay low during the data transfer time (tR).
We don't have a ready example for you for interfacing a NAND flash memory using the EMIF on LC4357. The part number for the NAND flash memory you referred to has been EOL'ed and no documentation is readily available.

Sunil
Hi Sunil,
Thank you for your commentary.
That means I can not drive the nanf flash K9WAG08U1B-PIB0 by TMS570LC4357.And do you mean TMS570LC4357 has been EOL'ed? But the page display it is preview.
I also need todrive a SRAM IDT70T3539M.I use the SDRAM to test it,but I failed.Are there other points to note except the"CS0" pin?

I meant that the NAND flash part number is EOL'ed. The 570 is still in Preview, as indicated.
How is the SDRAM connected? Can you provide a connection diagram as well as your software that configures the EMIF?
Regards, Sunil
Got it.
Thank you!
The attached one is the connection diagram and the code is the example.
In addition, I would like to ask how to enable the PLL1.I configured the parameters in HALCOGEN,but Idid not find changes.
