I meanwhile adjusted Makefile and test app source code to start from addres= s 0xA0000000. This seem to work well. My test app is running now. Because it's just a test app, I think it's OK to put it at the beginning of= the external RAM (so at address 0xA0000000). No use in trying to move it t= o another region in the external RAM, is it ? > = > Note that in my example I used /dev/sram0 (on-chip 128K SRAM), not /dev/r= am0 > (external DDR2 RAM). > = > baruch > = [Filip] If I'm right (have to verify though), i.MX27 does not have any SRAM= on board. So, I guess external RAM will be the only option. Because the te= st app resides in the external RAM, it won't be possible to test the whole = RAM. But I think we can live with that limitation.
