RE: Reading and writing from/to VME device

I'm using the MVME6100 board with the Motorola driver for linux v3.5 (kernel 2.6.15). I'm not sure what a Linux v3.5 is - Montavista? There are patches available from Motorola to the vanila kernel if you're interested in using something newer than 2.6.15. I try to access the CSR registers of

RE: Reading and writing from/to VME device

I tried to assign it to some other value (just a guess like 0x1000, which I think is 0x1000 in A16), and then try to read through as many addresses as the size of the window contains. Your code indicated said you're using A24 addressing. You should assign an A24 address. I get

MAC driver issue

I have no doubt it is with the driver. I am somewhat fortunate in this instance that I have a nearly identical setup - this is an FPGA based system I can swap the FPGA firmware, get an almost identical kernel with a slightly different NIC, and everything works - same

Stupid Telnet Question

I'm using ELDK 4.0 on a custom PPC74xx board, and NFS mounting the root file system. When I use the default NFS directory (e.g. /opt/eldk_4.0/ppc_74xx) read-write, I can telnet into the board fine (after modifying /etc/xinetd.d/telnet of course). But this default directory is overkill for my

Debugging with no serial port

This may be more of a question for GDB folks...but I'll post it here because it relates to embedded systems as well. I'm trying to validate some signal processing software on an embedded Virtex4 PowerPC 405. Basically, the validation consists of calling functions and looking at their outputs.

Cache coherency question

Tim I'm using an MVME6100 with Linux 2.6.14 and experiencing what I Tim think is a cache coherency problem. An external PCIX master Tim performs a DMA transfer of a well known data pattern into SDRAM, Tim but when the device driver goes to look at the data it is mostly Tim okay, but

Multiple MPC8xx SCC ethernets

I'm looking for patches to allow multiple SCC based ethernets on MPC8xx based boards. The 2.4 kernel releases only allow selection of either SCC1, SCC2, or SCC3, but not all three at the same time. Twice in the last few months, there's been a thread discussing this but I've never seen any code

question about Linux 2.6 with Xilinx ML-403

Grant, I know I could probably figure this out by looking at the GIT tree directly (which I'm planning to do) but could you summarize how much (which devices) of the ML-403 is supported by your patches? Serial? (which Xilinx core) Ethernet? (Hard-Core PLB TEMAC?, Soft-Core PLB EMAC? Localink

question about Linux 2.6 with Xilinx ML-403

Ethernet? (Hard-Core PLB TEMAC?, Soft-Core PLB EMAC? Localink TEMAC? Is 10/100/1000 supported, or is there only 1 rate e.g. 1000 supported?) No. I've ported the 2.4 driver, but I haven't got permission to release it yet. (I'm a contractor; I don't own any of the work I do) Which 2.4

PPC Linux support for Tundra TSI148

Does anyone out there have any real world measured performance of a Linux PowerPC (kernel module + user space application) doing 2eSST VME transfers with the Tundra TSI148 chipset? Tundra has a Linux driver available for the Motorola MVME6100 , but told me they don't have any performance data

Debugging tools

I was hoping to be able to bring up gdb, download an elf file to the target and step through a program to see where it is going off the rails. Assuming you have the Xilinx EDK tools installed, there is a program called xmd that acts as a standalone debugger or can communicate with gdb
