  • Ein neuer Monat - ein neues Update!


    Dieses Update behebt ein Problem mit der Initialisierung des Clock Ports, welches einige Kunden die ein Silversurfer RS232 Interface benutzen gemeldet hatten.


    Eine weitere Verbesserung ist der 256k REU Speicher "wraparound" - Wir halten noch immer Ausschau nach weiteren Programmen die in dieser Konfiguration nicht richtig funktionieren, typischerweise wenn diese versuchen die REU Grösse zu erkennen - bitte lassen Sie es uns wissen wenn Sie über solche Software stolpern, so daß wir diese zu unseren Testfällen hinzufügen können.


    Die Änderungen im Detail:

    Code
    1. Menu System:
    2. - Reworked Clockport initialization and -device detection. This fixes a tricky bug that on some setups prevented a connected Silversurfer to work when the program using it was started from the filebrowser.
    3. FPGA Core:
    4. - The REU configured for 256KByte did incorrectly wrap around the memory at the 256KByte boundary. A real 256KByte REU is really a 512KByte device with half of the RAM chips missing, with the result that the upper half of the memory banks accesses "open space".
    5. This release corrects the incorrect wrap around - but does not implement the somewhat tricky behaviour of reading from this unconnected memory yet (we are working on it).
    6. Some programs apparently rely on this behaviour - If you can identify any such programs that use the REU and which do not work correctly after the update when the REU configured for 256KByte please tell us so we can add them to our testcases.
    7. All other sizes are not affected, so you can always use the 512KByte config instead, which should make those programs work.


    Wie immer können Sie das Update auf der Chameleon Seite in unserem wiki downloaden.


    Viel Spass!
