BSP Limitations Related to AMD DBAu1500 Development Board Hardware Issues
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.
BSP Limitations Related to AMD DBAu1500 Silicon Issues
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.
