How to test the DDR memory with burst visit mode?

Hi,friends, I designed my MPC8360E board with 1GBytes DDR-1 memory, I built two demo boards, one is 533/266/400, the other is 660/330/400. The lower frequancy board is no problem for our program, but the higher frequency board is always problem about the data transmit on ethernet. I want t

Hello, This is my first post to the linuxppc-embedded list. Please forgive me for jumping in late onto the CPU15 workaround discussions, but my company is very interested in finding an efficient fix for this silicon errata on our devices. I applied the patch submitted by Scott Wood to our pa

Hi Swamy, I have seen this sometime before I think, but don't remember why. I see that udelay depends on loops_per_jiffy, have you looked to see what value it is? Maybe it's garbage and some large value? Have you tried dumping the __log_buf to understand how far it got thru booting the kernel be

xilinx_hwicap driver problems

2008-05-14 Thread Will Kritikos
I am having some trouble using the xilinx_hwicap driver in Linux. I am using version 2.6.24-rc8-xlnx of the Linux kernel from the Xilinx GIT repository. The xilinx_hwicap driver is statically compiled in - not a loadable module. I am using the opb_hwicap device on a V4FX60 FPGA, Linux running on th

I bet you're using ARCH ppc... It looks like in arch/ppc/syslib/virtex_devices.c: #define XPAR_HWICAP(num) { \ .name = "xilinx_icap", \ Should probably be: #define XPAR_HWICAP(num) { \ .name = "icap", \ now. Can you make this change locally and verify that it solves the probl

Steve, Yes, this fixed that problem. the following is now printed when booting the kernel. [5.866230] icap icap.0: Xilinx icap port driver [5.866401] icap icap.0: ioremap 4020 to c500 with size 1 The icap is at address 0x4020 on my system, so that seems correct. However,

2008-05-14 Thread Stephen Neuendorffer
OK, that's progress. The next thing I'd check is that you are *not* using the JTAG configuration mode, as this disables the ICAP. You can also try turning on the DEBUG flags in the driver itself. During open() the driver attempts to read the IDCODE from the hwicap to get it back to an initial
