Hi All, I am getting data access exception(0x300), when I am trying to use one GB SRAM using high memory enabled. I am setting Virtual addr of kernel base as 0x90000000 and low memory as 0x40000000. Processor used is MPC7447 and controller is MV64360/62. Thanks, -Ashok ** Sent via the linuxppc-embedded mail list. See http://lists.linuxppc.org/
