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...

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...

For anybody who is interested this discussion was continued on the ETH Oberon Mailing list:

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 ...

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...

The tool I use to backup Project Oberon SD card images to my PC using Windows 10 is called DD for Windows: http://www.chrysocome.net/dd The command I use to read 320 MB (the 256MB DOS partition and the 64MB Project Oberon file system) from the SD card is, for example: dd if=\\.\PhysicalDrive6 of=Emb...

Memory addressing limits are defined in Bootload.Mod. For the Artix-7 XC7A35T, using 192KB BRAM, MemLim is defined as 030000H. Read Section 8 Storage layout and management in the Project Oberon documentation (Astrobe menu > Help > Project Oberon) to see how the address range is partitioned and manag...

Yes - that is my understanding. Vivado issues the warning: width (24) of port connection 'adr' does not match port width (18) of module 'RAM' If you prefer you can modify the adr parameter in the RAM statement in RISC5Top.v to match the address width actually used in the RAM module for your particul...

My understanding is that only one SPI device on the RISC5 system is active at any time. In section 17.2.3. The SPI interface for the SD-card (disk) and the Net of the book Project Oberon - The Design of an Operating System, a Compiler, and a Computer. it states: Here, however, no use is made of SPI'...

The attached source code shows how to measure temperature and humidity via I2C using Digilent's Pmod HYGRO board.

It should work on any of the development boards with I2C that are supported by v7.2 Astrobe for RISC5.
