TMS320F2812: Adding External RAM and Flash Memory to ezDSP

Hi Aimal,

Refer these wikis:
processors.wiki.ti.com/.../External_Interface_XINTF_Type_1_FAQ_for_C2000
processors.wiki.ti.com/.../External_Flash_Programming_on_C2000

Also, you can search the forum for any additional info other than User guides.

Regards,
Gautam

Thanks Gautam, but the links describe how the external flash can be programmed. my question was how can I attach the external RAM and ROM to the controller and how can i tell the controller to load program from external ROM and use external RAM????

I should've been specific with link no.1.
processors.wiki.ti.com/.../External_Interface_XINTF_Type_1_FAQ_for_C2000

Did you go through the XINTF userguide for your device? www.ti.com/.../spru067c.pdf

Yes Gautam, I have gone through spru067c.pdf. This explains well, how to configure chip select signal. Let say i program external flash via some flash programmer and connect it to zone-6. Now how can i tell the processor to Load program from that external ROM.????
Even if i mention in .cmd linker file the .text area to be in zone-6, build that project, burn to external Flash, Now how the TMS320F2812 would know that the .text code is in external memory attached to zone-6.???
Thanks for your reply.

This is the closest doc I could find for you: Its for F2834x but try following for F2812
