Re: Self-unloading With Modules.Free?

Free should be used with great care and only when necessary. A situation where it is necessary and generally OK is when you are in the process of developing a new module and want to test it after making changes and recompiling. In that case you should have a good understanding of how the module work...

Re: Project Oberon Workstation on Digilent Nexys 4 Rev B

Great! I'm pleased to hear that you have got it working. I'll add a note to the installation instructions to point out that the folder structure should be maintained when unzipping the Verilog files. We deliberately use the same folder structure as the official Project Oberon release. Is that why yo...

Re: Mapping to Nexys4 Cell RAM board

Thank you for the additional information. We used to supply the MCS files with the bitstream file but discovered that not only are these different for different boards, but also between different revisions of the same board :( Anbody else reading this should note the following: You need to refer to ...

Re: Project Oberon Workstation on Digilent Nexys 4 Rev B

(To minimise any confusion I've created this new topic and moved the original message from the Arty A7-100 topic.) We do not have the older Nexys 4 Rev B board so we are unable to test Project Oberon Workstation on it. However, it appears to similar enough to the Nexys A7-100T (which we are able to ...

Re: Mapping to Nexys4 Cell RAM board

Make sure that you are only using the files supplied for Embedded Project Oberon if you are using the constraints file you attached here. These files must not be mixed with the files supplied for Project Oberon Workstation. The Embedded Project Oberon BootLoader ROM file is called prom.mem. You shou...

Project Oberon Workstation on Digilent Arty A7-100T

To help new users get started we have now made available, free of charge, a disk image, Verilog sources and bitstream file specifically to run the Project Oberon Workstation on the Digilent Arty A7-100T FPGA development board and associated Pmod modules 'out-of-the-box'. This release is based on the...

Re: Stimulus driven interrupts?

Oberon's interrupt capabilities are part of Project Oberon and the RISC5 design - they are not peculiar to Astrobe. Unfortunately we have not had any experience in what you are attempting to do. However, I recommend that you check out this website produced by gray, another Astrobe user and frequent ...

Re: License and fair use for Oberon System?

Yes - that is the license that applies to any Project Oberon software, included with Astrobe, that you can also download from http://www.projectoberon.com We supply additional Oberon source code modules with Astrobe that we have developed (e.g. HCFiler, I2C etc). These are subject to additional (but...
