Try:

int * MemSrcAddressA = (int *)0x3C000000; // Ext. Mem CS0

*MemSrcAddressA = 42;

Hello,

now I know how to initialise, read and write data from an external RAM.

In the Keil-uVision you have to tell the linker the address of the external ram. Than you can assign an C-source to RAM1, which is located at [0x2C000000-0x2C07FFFF].

Thomas
