Hi Dan, Thanks for the help, it was the BlockGen which I presume was not allowed to run fully/ properly. When is it generated out of interest? Anyway, I took...

I am now running a test bootloader. It is written in (restricted) Java and built into the FPGA image as an initialization of the method cache. It uses the...
Hello all, I have a spartan3 board, and have JOP running on this board. I am using the JOP S3k projekt, and have added more I/O's( switches, leds and...
... Actually you should *not* add any specific IO devices to sc_sys.vhd. sc_sys is meant for internal IO devices only. The next level in the IO mapping is...
On Tue, Mar 11, 2008 at 9:01 AM, mortensorensen81 ... Hi, Morten. I am also a newbie, and I just went through this myself. Any given JOP system may have one or...
Dan, ... does not look like a newbie with what you're acutally doing with JOP and your fine description of the IO system ;-) Perhaps you would like to add this...
... Perhaps not a JOP newbie any more, but still a VHDL newbie. ... I made a preliminary edit: perhaps others can improve it. ... See? I really am a VHDL...
Hi, Dan and Martin. I want to thank you both for your quick answers. I still fail to see the address connection, this is why I added some code to sc_sys. I...
On Wed, Mar 12, 2008 at 5:05 AM, mortensorensen81 ... Your scio_xxx.vhd file defines the starting address for the sc address range. By convention, the base...
On Wed, Mar 12, 2008 at 5:05 AM, mortensorensen81 ... Sorry, my earlier reply failed to answer your specific question. scio_min.vhd generates a multiplexer...
... The mulitplexer is here: sc_io_in.rd_data <= sc_dout(sel_reg); sc_io_in.rdy_cnt <= sc_rdy_cnt(sel_reg); The mapping is done by using the correct index for...
Hi, Geeez so easy :) Thanks to the both of you for your answers, it really helped me. I finally managed add a peripheral device (my VERY simpel vga "driver")...
I once purchased the Altera Cyclone EP1C6Q24 from jopdesign.com (item #CYC1M32M), and I'd like to do so again, but I'm in the US, and the Euro conversion rates...
Hi Martin, I know this is an old thread issue but I still can't figure out how I'm getting 'array out of bounds errors'. There any chance you could look at my...
Hi Chris, the last time you sent me the files I was not able to compile the project from the sources. Have you cleaned up that issue? In that case I can take...
Trevor, there is no US vendor that trades that board. There has been one in Germany, but he dropped the board as He tried to get a deal with Xilinx :-( Cheers,...
Hello, I am currently using JOP to investigate the use of a java run-time verification engine on code executing in an embedded system (in this case, JOP on...
... Sounds interesting. ... That fits to the serial line baud rate: 115 kBit => ~10 kChar/s => 100 us per character. ... I would use a output buffer for your...
... Thank you for the answers Martin. I did proceed with a test arrangement using this model and it works a treat. If I performed WCET analysis correctly, it...
... I agree that this is very slow. Perhaps you can nail it down where that many cycles are spent for this simple operations. ... Why do you need wait/notify?...
... My concern is that I'm not sure what happens if the writer thread pre-empts another thread while it is in the middle of writing to the buffer the writer...
... Ok, using synchronized avoids mixing output characters, but introduces the blocking time. When you can skip the output in one period what about setting a...
Hi Martin, I've still looked at this for a while now. Any pointers on what's going wrong? I was wondering what the steps were to upgrade JOP to a JRE 1.4? Kind...
Hi Chris, ... I got some files from you, but I never got a version that can be complied from the source. The makefile, which was part of one version you sent...
