I know that the file related to the linux booting on x86 is bootsect.S ,setup.S ,but I don't know which booting files are related to leon.I just find the...
Hi Nagaraj, Last year I developed an audio core to play audio files using leon2+xsv800 board. It is a good example on the issues you shold be concerned when...
Hi, I seem to be having very strange problems with the store double word (std) instruction. I am running LEON using an xc2v6000, on a board which does not...
I am busy with writing a PCI driver for the GR-PCI-XC2V. The driver shall work under RTEMS. Now I have finished the first version and tried to send data to the...
Hello Tom Indeed the PCI interface on the GR-PCI-XC2V board does work. We use the PCI interface together with the DSUMON option '-pci' to download programs to...
Ooops, I figured this out now and it was just my own stupid fault. I had made the rash assumption that some other sub-system in Leon turned all memory accesses...
Dear Eduardo:
I would like to have the source code of IP and driver of your audio controller. I hope they can help me learn the SoC with Leon as core as soon...

Hi, I am trying to adapt the synthesis-scripts to my xc2v6000-ff1152-4 FPGA and encountered a problem with the bitgen.ut-file (see below) from the gr-pci-xc2v...
Hi, I have a few questions related to ERC32, Leon1, and Leon2: 1/ What are the main differences between the 3 processors? 2/ Does ISS-3.0.5 support Leon1 and...
Hi Jiri, Right now I am using leon with external Sram, I would like to connect even a flash memory to leon to which I can write and read. Any tips are...
Hi all, I have a question concerning the clock period and ram access time. Upon changing the clock cycle from 20ns to an arbitrary number (say 5ns), problems...
Hello, I am a newbie to the Leon-sparc environment under rtems, and I would like to use 64 bit integers in my application. I ran some test code to show that...
Hi all, Just goes to show you shouldn't depend on Windows tools. Under Windows I could only see three files, but under Linux I could see four. Sorry all. Bob...
I moodify the linux-2.5.75-patched(run on tsim-leon-mmu) so that it can boot from ram,but it's show "bad gzip magic number" while decompressing kernel.why?...
dsuImage does not work for me neither It writes 3 lines and hangs after launching the kernel. the pc is stuck in f0004004. I suspect an mmu misconfiguration ...
Printing 64-bit ints is not supported by Newlib (RTEMS C library) since it is not ANSI C. A way around is to make a function that converts a lon long to a...
Dear Pschaumont, thanks to answer me. But I need your help again. I'm starting to study the processor Leon/Sparc now, and like you toll me It's possible to...
I've had no trouble compiling the kernel with targets such as tsimImage, tsimbzImage, etc. The output is tsimbzImage in my arch/sparcnommu/leon_tmp/...
There is no overhead imposed by tsim. The large kernel size probably depends on our kernel configuration options or a large rdimage. A simple kernel with sash...
The VmLeon directory is one you have to design yourself. It is not available for download, because it is specific to the kind of hardware platform+OS you are...
Jiri - Thanks for the quick reply. I'm using the sample rdimage off the linux page. Is there a quick way to reduce the rdimage size? ... it's ... FPGA. ... ...
The userspace provided from our linux page is built from glibc, so rdimage will be large. A better option might be to generate an rdimage with uClibc, using...
Could someone explain in what situation an AHB Hburst of wrap4/8/16 is issued by an AHB master? How should a slave memory controller respond to it? What about...
