TM4C129ENCPDT: Bulk Erase in Spanison External memory

Shijin Krishna
Prodigy 175 points
Part Number: TM4C129ENCPDT

Hello All,

Iam using 256Mb external flash with TM4C129ENCPDT controller.

Iam able to read write and sector erase the flash. Thanks to TI code for the Macronix flash.

Request your help if anyone had same issue on Bulk Erase command with Spanison flash and was resolved.

I have reference of a post here where exactly same problem was faced:

http://e2e.ti.com/support/microcontrollers/tiva_arm/f/908/p/392228/1449664#pi320098=3   ( How to access external memory connected to TM4C1294XL )

The resolution would help me.

Thanks all 

Regards

Shijin.

    Hello Shijin,
    If you have read, write and sector erase working, that proves you have properly configured the TM4C129ENCPDT controller. Have you considered asking Spanison for assistance as this is likely an issue with their part? Perhaps a community member of this forum may be able to offer assistance based on their experience, but debugging parts from other companies is beyond the scope of the help that I am able to provide.
