How to jump from SRAM to DRAM when porting Linux onto OR1200. by avamsi on May 2, 2012			avamsi Posts: 54 Joined: Apr 16, 2012 Last seen: Jul 30, 2014
Hi, Actually we are trying to port the Linux onto the OR1200. In the FPGA build configuration, after reset it is jumping to SRAM(less memory size) location. But we will boot the Linux kernel into the DRAM over JTAG. How we can jump from SRAM location to DRAM location where actually kernel should start execution. So far we built the kernel and ported in the simulation environment.When we try to port the kernel onto the HW,after copying is done, we need to set the PC to the reset vector and set entry point. Please explain how I should proceed after copying kernel in this case. Thanks, A.Vamsi Hi, Actually we are trying to port the Linux onto the OR1200.
