ERROR: IO 'dataout[7]' is unconstrained in PCF

[FraEgg]

Hello Michael,

many thanks for the romulator 6502. it really is a great tool.

I have a problem with creating my own custom firmware. The "make program" process is always aborted with an error message. I just can't find the problem and hope you could give me a hint.

I am using a Raspberry Pi 3+ with the latest RaspianOS (64Bit).

When I generate the files via your website, the firmware works on the romulator.

Best regards Frank

Hi Frank, Thanks for letting me know. Interesting, I haven't seen that error before. First, could you check a couple of things: the version of apio currently installed on the pi (apio --version) Also, you may need to pull the latest from the bf-romulator repository, depending on when you cloned it. I made some changes recently to update to apio version 0.8.1 and changed a bit in the verilog. Would you mind sending me your config files, so I can see if I can reproduce the same error? Let's start there and hopefully can get to the root of the issue. Thanks,

• Mike

I can report that the Romulator 6502 runs very well in a Commodore 1541 floppy drive. I have four floppyspeeders running with it and the loading time with the additional RAM and parallel cable is accelerated by a factor of 27 (DolphinDos).
