Astrobe Forum

I'm asking for advice in order to program in Oberon and generate ARM Thumb instruction set code with the new Astrobe 8.1.1 for Raspberry Pi RP2040. I'm using the Personal Free Edition, are there more target CPUs in the Configuration of the Astrobe Professional version? Or do I need to Edit one of th...

I don't know right now, I need to retest the generation of the bitstream. But as long as I remember I configured FPGA once and showed to students many times until one day (after a couple of years) it fails like I mention with a gray pattern on screen. Then I certainly tried to reconfigure and reburn...

Solved! The problem is solved by adding and mapping prom.mem correctly in Vivado, in a parent directory as showed in PROM.v with: initial $readmemh("../prom.mem", mem); I tried to relocate several times, but Vivado always failed to find the file, despite modifying the path in the Verilog readmemh fu...

No LED is on, or blink or nothing. The only LEDs on are DONE and just an instant BUSY after PROG is pushed. After CPU_RST pressed, there is no change. I'm baffled.
On the same board I could start Embedded Oberon without problem but not PO WS.

I'm trying to map the Project Oberon Workstation on the Nexys4 Rev B with the provided XDC file by email to me by you. After generating the MCS file, configuring the QSPI FlashROM on the board, and burning 4GB micro SD card with the image provided, connecting keyboard and VGA monitor, putting Jumper...

Thank you for your guide and advises. I have Embedded Oberon already running in the Nexys4 Cell RAM board. Just for the sake of completeness: Between the step 4 and 5 there are more ministeps not evident for me: 4.1 Choose Format: MCS 4.2 Choose Memory Part: s25fl128sxxxxxx0-spi 4.3 Choose a Filenam...

For Astrobe v7.2 for RISC5 I've been trying this XDC configuration, attached.
I did not have success communicating to Astrobe after configuring the FPGA in the board.
I need some help also to generate the ROM file; I'm only trying by USB JTAG with PROG UART connector.
