The fix for this problem is now available in v7.2.3 Astrobe for Cortex-M3, M4 and M7.

Minor maintenance upgrades v7.2.3 Astrobe for Cortex-M3, M4 and M7 have now been released. See What's New in Astrobe for Cortex-M3, M4 and M7 for a summary of the new features and bug-fixes since v7.0. If you are a registered user of the Professional or Personal Editions and your support period has ...

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.

The attached source code shows how to measure temperature and humidity via I2C using Digilent's Pmod HYGRO board . It was been tested on STMicroelectronics Nucleo-L152RE development board but should work with little or no modification on any of the development boards with I2C that are supported by v...

To help new users get started we have now made available, free of charge, a disk image and Verilog bitstream files specifically to run the Project Oberon Workstation on the Digilent Nexys A7-100 FPGA trainer board 'out-of-the-box'. This release is based on the Oberon sources (as at March 2020) and V...

We have successfully implemented Astrobe Embedded Project Oberon on the XC7A100T FPGA device of the Xilinx Artix 7 family. This means that Astrobe can have 480 KBytes of RAM available to it. This is 2-3 times more than our other supported implementations, allowing for more / larger applications to b...
