TMS570LS3137-EP NAND interface

Posting for a customer:

I am trying to interface TMS570LS3137-EP to NAND Flash (Samsung FLASH - K9WAG08U1B). The TRM mentions about interfacing to the NOR Flash but not the NAND Flash.  Can TMS570LS3137-EP be interfaced to NAND FLASH?

 

I did find an E2E post referencing TMS570LC4357 interfacing with NAND Flash https://e2e.ti.com/support/microcontrollers/hercules/f/312/p/434580/1562213#1562213

 

The response there was:

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.

 

Does this hold true for TMS570LS3137-EP?

 

Thanks!
