hi it j -3 a jus need a configuiration guide to help me have the right choises (you know they are so many) and i have nort that time speacilalla we are in...
Hi A LEON SnapGear guide is freely available from the download area where you got snapgear and the toolchain from, www.gaisler.com -> Downloads -> Linux. ...
Hi, Thanks for reply. I saw you configured COL = (9), but shouldn't it be 10, if you were also using the memory stick with board from Xilinx? Regards, Jin ... ...
Hallo, I've configured a design with 2 Leon3-Cores (via make xgrlib) after make ise && make ise-prog-fpga I tried to connect to the board with grmon via...
I got the same problem before. That means ur leon3 is not detected. Check your config.vhd and compare it with reference design. Good luck. ... board...
I have loked my config.vhd: library techmap; use techmap.gencomp.all; package config is -- Technology and synthesis options constant CFG_FABTECH : integer :=...
I remember we disabled uart and enable jtag at that time. then it worked. But actually you can enable both all them. anyway you can give a try. probably it is...
About the timing constraints - I use exactly the same as they were defined for template desing mentioned previously. I set the DDR clock to 100MHz (original...
I'm using a template design from grlib-gpl-1.0.17-b2710/designs/leon3mp. My task is to port Leon3 processor to UMC90 nm technology and I've got several...
Hi Jan again, I'm working on adding another processing core in the grlib via the AHB Bus. It'll need access to memory to load an OS on it and access to the...
Hi, I am trying to run Linux 2.0 first on tsim and then on the LEON3 in actual FPGA. The steps 'make xconfig' and 'make dep' were successful. However when I...
Hello all, I meet a bug with grlib-gpl-1.0.17-b2710 and Synplify. It occured yesterday after I had to re-setup Libero because of a problem with WaveFormer...
Hi, You need to use the right compiler. sparc-elf-gcc is for Bare C/C++ and eCos, sparc-rtems-gcc is for RTEMS, sparc-linux-gcc is for Linux 2.6 with GLIBC,...
OK, I have some output from GRMON-RCP as an apb_slave to start off with (even though I've added the ahbmst component too) but it's coming up as unknown device...
Hi Jiri, just for my understanding I have got a question about TSIM's handling of endianess. I assume that there's a little endian host. The AHB emulated...

I think so . I have the same problem. I think that is because GRMON lib doesn't have your own device information. So it cannot be displayed on the screen. I...
This synplify bug has been reported to Synplicity and Actel about a month ago. No action from their side so far. Obviously, I can not fix there bugs. You could...
Hello, I want to change the device from the template leon3-avnet-ml401 to the device XC4VFX140. The /c/grlib/boards/avnet-ml401-xc4vlx25/Makefile.inc was as...
Disable the giga-bit ethernet MAC option in xconfig and try again. You might need to remove the associated timing constraints for the giga-bit signals from the...
Hi, I use the memory module devlivered with the board. Configuration of the DDR controller I use looks as follows: -- DDR controller constant CFG_DDRSP :...
Hi, I can't get it to work as well. It seems to me now that my synthesis has some problem. The DCM ddrphy/nops.read_dll is not instantiated properly. How's...
I was trying to simulate Leon3 by Modesim. Butwhatever I do... original prom.srem, my own hello.srec etc. I've got these results: ... # apbctrl: slv7: Gaisler...
As I said, remove the timing constraints related to the giga-bit signals in the .ucf and .xcf files. Then do a 'make distclean' and 'make ise' again. The...
Have a look at the error message: Annotating constraints using XCF file 'leon3mp.xcf'" ERROR:Xst:1587 - Line 9: No signal name matches phy_tx_data(*) pattern. ...
TSIM uses the host's byte ordering to optimize performance. If you emulate memory in an AHB or I/O module, byte and half- word writes must be endian swapped on...
Hello We are 3 students who are having some problems while trying to add a new output port to some Leon 3's entities. We want to have a new output port on...
