Hi: I am not the expert here, so forgive my idiotic response. But if you see "command not found" I would guess you don't have the dsumon program in your...
I observed are two serious problems (at least for me) with the following code: 1. The sparc-rtems-gcc optimizer(-O2) produces wrong code 2. Mixed 32/8-bit...
Hi all: We are working with two boards GR-PCI-XC2V-FPGA and we would like to know if it is possible the communication between LEON boards through PCI bus. And...
Hi! I'm using the gr-pci-xc2v evaluation board with a Leon2 with SDRam controller and I am not able to disable SRAM and map SDRam to address 0x40000000. I've...
Dear Jiri, I am trying to run hello world program on LEON target board (alterna nios board with APEX fpga). I haven't configured the leon to have sram or sdram...
Dear Jiri, I have another problem, apart from the one reported before. Now I am trying to use LECCWS1.1.5 instead of 1.2.2 and I get the same result with...
Hi! I'm having problems to configure the FPGA on my gr-pci-xc2v board in JTAG mode. In Impact I have enabled the "verify" option and it reports failed...
... When you disable the SRAM, the SDRAM starts at 0x40000000 (see paragraph 8.9.2 of the Leon manual). You have 64Mbyte of SDRAM, so it will wrap around at...
1. You access the same memory location using pointers of different types. This is called "type aliasing" and is not allowed by the C Standard. Pointers of...

... Well, I would expect the behavior that you describe but I'm not getting it: $ grmon-eval.exe -i GRMON - The LEON multi purpose monitor v1.0.4 (evaluation...
Hi All, I am wondering if DSUMON comes in LECCS pakage. But I cannot find any in my directoris. Should I get DSUMON seperatly? If yes where? Is GRMON replacing...
Thanks Edvin, for your reply, especially for the info about prohibited "type aliasing". I really didn't know ... Usually I do not write such kind of code. ;-) ...
Hi Stefan, To be honest, I hadn't realised that it worked like this, but I think the explanation is as follows: 1) For SRAM it is possible to have four banks...
... this ... with ... Yes this explains the behavior. But I have still the problem that disabling SRAM via bit 13 of mcfg2 does not work. Do you have any idea ...
... OK. I think I know what is happening. Try setting it with the 'mcfg2' and then look at the memory with the command 'mem 0x80000000' or the command 'leon'. ...
... Yes, GRMON is a front end which combines a simulator and the DSU monitor. DSUMON is no longer distributed with the Leon VHDL model. See the GRMON user...
... Have you tried to run your program from grmon? grmon will initialize memory configuration registers to correct values. You can also put your application in...

... That did the trick. Oddly, I remember an older thread where it was recommended to use mcfg2 to set the contents of the register ... Thanks for your help. ...
Dear All, I have a problem with GRMON when I want to start with -gdb option. Can any one please tell me how to solve this problem. Thank you, Karthik. ...
... Okay, I'll try grmon tomorrow and let you know. ... That's what I'm usually doing (faster than burning flash). From RAM the results are the same. Only for...
Hi everyone, I want to run simple hello world program on my LEON target. So far I have been able to connect the system to GRMON. But when I sun the program I...
If I have understood correctly, you do not have any SRAM or SDRAM in your system (according to an earlier post of yours). At least GRMON/DSUMON does not seem...
Dear Richard, According to the Leon manual, if I have AHB RAM, it starts at address 0X60000000. I hope to load it there (if I am not wrong). I found this info ...
We should check, whether we are using the same Leon configuration. I have "hardware mult/div" enabled in both and no FPU. Maybe you could send me your Leon...
... OK. I have tried the same thing, using a Xilinx XC2V3000 board (GR-PCI-XC2V). With 64k AHB ram at 0x60000000, and the program compiled with sparc-rtems-gcc...
Dear Richard, Can I ask you one favor. In you LEON configuration, can you disable the SDRAM and run the hello program. I mean configure your LEON with out any ...
... Yes this works fine. Attached is GRMON output. The AHB RAM is 64kByte in size. bash-2.05b# ./Desktop/grmon-eval -i GRMON - The LEON multi purpose monitor...
