The following BSP limitations are related to hardware issues on the AMD DBAu1500 Development Board:

  • There is no support for USB function.

  • There is no support for the IDE ATA/133 controller.

  • The PCI bus does not fully support devices behind a bridge.

    This issue is related to bus latency for transfers initialized by the Au1 PCI 2.2 Controller for PCI device behind bridge.

  • The boot loader and KITL only support Au1 on-chip Ethernet controllers.

  • Audio input uses the J17 connector or plug.

  • Audio output uses the J20 connector or plug.

The following BSP limitations are related to silicon issues on the AMD DBAu1500 Development Board:

  • The OAL sets the OD bit in the Config0 coprocessor register to fix or work around silicon-related problems.

  • If the BSP_YAMON flag is set, the boot loader and the BSP are compiled and built in a way that allows you to flash the boot loader to address 0xBFD00000. In this mode, use the YAMON autorun to jump to the boot loader.

  • The USB host driver reads enable the register to work around the silicon problem twice.

  • A USB host controller silicon problem might cause USB devices not to work or to work incorrectly. As a result, the memory can be corrupted and the USB device can randomly crash.

    This problem is typical for USB mouse devices that have a 4-byte interrupt endpoint size. It does not affect the Microsoft® IntelliMouse®.

  • The static mapping uses two translation look-aside buffer (TLB) entries to work around silicon problems with the page frame when the size is greater than 4 KB.

  • Due to a silicon problem, the PCMCIA slot does not support 8-bit I/O operations on odd addresses. As a result, some PCMCIA cards, such as modem cards or Bluetooth cards, might not work or might work incorrectly.
