... Thanks! ... design. ... As a follow up to this email, there are two constants defined in Leon3mp.vhd that make use of CFG_USBHC that were not mentioned in...
Hi everyone I have a question about the integer pipeline. Something that I am slightly confused about is this -- let us say that there is a miss in the...
... <snip> ... Yes the CFG_USBHC constant should be removed. In the default design this constant is set to 0 and will not cause any problems. However if you...
Hello, I am trying to bring basic network connectivity up on a leon3-digilent-xup board in linux-2.0. I have synthesized a leon3 processor without MMU and...
Hello, "SIOCADDRT: No such device" comes from that no eth0 device is available (driver did not find any GRETH cores). The printout on the homepage can be...
Hi Jiri, I wanted to activate the interrupt for a little RTEMS driver in the TSIM simulation environment. When registering the interrupt vector number with...

... The IRQ assignment for the built-in is as follows: UART1: IRQ 2 UART2: IRQ 3 TIMER1: IRQ 8 TIMER2: IRQ 9 I have added this to the next version of the TSIM...
Hi Jiri, I am testing the example TSIM I/O module io.c. I wanted the io_read() function to be executed, but io_read() is only called when accessing the memory...

Hello Daniel, Hmm, I am able to connect to the board using grmon's "-eth" option though: "grmon-eval -nb -eth -ip 192.168.1.51". I thought the DSU and the...
If you are using the template I/O module provided with TSIM, then address 0x10000000 should work. If you are using an AHB module, make sure it returns -1 for...
Yes, I'm using the template I/O module, provided in io.c. I'm sorry, I think there was a typo in the last message. The address that I was trying and where the...

Address 0x1000000 is mapped on the first PROM chip select (PROMSN[0]), which is always accessing the built-in PROM. You can use 0x10000000, which will be send...
Hi, Thanks for the tips. We have successfully synthesized a Leon3 core with the scratch pad rams. We have also written a bmm file to initialize the BRAMs with...
You can either load your program with grmon, which will automatically store it in the scratch pad RAM, or wrap your binary with mkprom. The mkprom image should...
What config options should be used in order to include the prom? (CONFIG_AHBROM_ENABLE ? ) In order to not duplicate the program code inside the FPGA, can we...
Dear Jiri, now I've changed the template I/O module, so that is it imported as an AHB module. When I try to load the executable, TSIM says that the load ...
