I am wondering how to enable the 4MB of SRAM soldered onto the MPC5676R DAT516 daughter card. I have gone through the manual it indicates JP4 is the SRAM_SEL jumper but no details on how to actually get this to work. Do I jump 1-2, 2-3 leave it open? Then, do I map the 4MB into the SRAM area (0x40000000) or is this considered External (0x20000000). This may be basic stuff but its a mystery to me.
Any help would be appreciated. Thanks.
