good news, it finally works! The first problem was the port number. Despite I had enabled input and output in the windows firewall for the 65520 it didn't work. So I tested with 6442 instead (maybe e-mule or e-donkey used numbers in this range) and the line in stderr.txt showed gdb was listening, bu...

hello rolo, I have a Dragon32 with the half good OKI 64k ram chips. I made the few mods necessary to allow upper ram to be modified and then I tested write-read in a loop. It worked without problems. I will not change the roms, because it keeps being a Dragon 32, I mean there is no serial port and i...

hello, have tried creating input and output rules for the 65520 port in the windows firewall with the same result (fail). Then I have disabled the firewall, didn't solve the problem. I have tried to add the IP that my DHCP server gives to my PC, I make these two tries: xroar -gdb-ip 192.168.001.119 ...

Back again Ciaran, I have copied windows32 version and made the very same procedure. It failed too, so it is clear that I am missing or doing something wrong. I explain what I have done: I have created a folder with the xroar executable and m6809-gdb.exe then I start xroar with this .bat commnad fil...

Hello Ciaran,
I have started xroar v0.31 64bits with -gdb and then started m6809-gdb but the command "target remote loacalhost:65520" failed in my instalation.
I copy an image of the screen with xroar, m6809-gdb, and strderr.txt open, I hope you could find and tell me where did I go wrong.
thanks
Pere

Hello Rob, this remembers me the problems I had with the Lafumat controller trying to use 5.25" drives 1,2Mb. Acording to him, you could make adjustements when this error pops-up, but I have never succeeded with those drives. Finally, I gave up and now I have two 3.5" drives 1.44Mb that work without...

Hello, having seen that the board is from Dragon Data, I have searched my PC Dragon folders and finally I have found a very good schematics from P.Harvey-Smith dated April 2010.

thank you very much Ken! I added the header to the DSK files from that web page and didn't work on XRoar. Then I tried one of them on a Dragon64 and the NitroOS-9 BOOT screen simply hangs and does nothing more. Then I have booted with an OS-9 L1 and have had no problems to access all the directories...
