GPMC access an external SRAM issue

Elvis Wei

Hello,

The GPMC is not able to read/write an external SRAM after executing the MMUConfigAndEnable(); function.

Any possible effect between the GPMC and the MMUConfigAndEnable(); function?

Thanks,

Elvis

Hi Elvis,

In your previous post http://e2e.ti.com/support/arm/sitara_arm/f/791/t/292012.aspx
you have mentioned that the GPMC is able to access the SRAM in MLO(bootloader) but not in the application.

Have you tried accessing the SRAM in your application by disabling the MMU?
