The Nexys.xcd file - to my knowledge - defines the periphery of the Artix FPGA, which means the pinout.

Now i'm really wondering where the memory link (inbus, outbus, adressbus) is set? i simply find no definition for it in the file?

The command format for the Astrobe command-line builder is: AstrobeBuild configFilename <filename | full pathname> However, if you call AstrobeBuild using the <filename> parameter option and the file exists in the current folder, the following exception results: Path cannot be the empty string or al...

Raspberry Pi have defined Metadata Blocks to be used to configure RP2350 applications. These blocks are embedded in the executable UF2 format file. Details of these blocks can be seen in Section 5.9 of the RP2350 DataSheet. The initial release of Astrobe for RP2350 implemented an Image Def block usi...

A maximum of ten library search paths can be defined in the Configuration files. However it has been reported that an exception is raised during compilation if more than eight of them are valid. This bug affects every version of Astrobe. The problem will be fixed to eliminate this exception as and w...

On the SW side i managed now to install an Oberon task in the loop. Would like to autostart it on reset/power up. Assume i have to rebuild the image on the SD card then, right? Would you tell me how to do?

When compiling a module TypeExports which imports a module M1 both directly and indirectly (via module M2 ), an error message is incorrectly reported: Line Col 5 25 Error: parameters must be of exported types MODULE TypeExports; IMPORT M2, M1; PROCEDURE Test*(r: M1.R); END Test; END TypeExports. Whe...

When running on Embedded Project Oberon, SwitchTest.Run gives:
Switch 2 is on
Switch 3 is on
Switch 6 is on
Switch 7 is on

As my Nexys A7 board has 16 switches, I have changed SwitchCount = 16; but they do not show up?

Is it possible to attach and read in a USB keyboard directly when using Embedded Project Oberon on a Nexys A7 board?

Incorrect code is generated when SYSTEM.SP is used as a parameter to BITS e.g. IF 2 IN BITS(SYSTEM.SP) THEN . 8 08H 02004H movs r0,#4 . 10 0AH 04201H tst r1,r0 . 12 0CH 0468DH mov sp,r1 it should be something like: IF 2 IN BITS(SYSTEM.SP) THEN . 8 08H 04668H mov r0,sp . 10 0AH 02104H movs r1,#4 . 12...

Yes. If you have the Professional Edition you can confirm the order of module initialsation by disassembling the application and looking at the sequence of <modulename>..init calls in the initialisation code procedure (e.g. Blinker..init) of your application.
