- README: Wind River SBC8548 Evaluation Board
- This file contains board-specific information for the Wind River SBC8548
- target board. Specifically, this file contains information on any BSP
- interface changes from previous software or hardware versions, and
- contains caveats that the user must be aware of before using this BSP.
- ------------------------------------------------------------------------------
- Version 2.0/2
- Released from Wind River for Workbench 2.6, VxWorks 6.4
- Support the latest Wind River SBC8548 rev.2 board.
- Add CPU rev.2 update.
- Add TFFS support, using the SODIMM 64MB flash as the TFFS media.
- Add PCI Express support, tested using a Intel 8257x NIC.
- Modify SODIMM Flash base address to solve the static TLB issue.
- Modify SRIO to use m85xxCCSR driver.
- Modify auxClock and nvRam to get BSPVTS passed.
- FCS Version 2.0/1
- Released from Wind River for Workbench 2.5, VxWorks 6.3
- ETSEC functionality has been added including checksum offload support and
- filer capability. The user should rebuild target/src/hwif for etsec.
- VXBUS infrastructure is now used for ETSEC (and SRIO, which has not been
- tested). These devices are configured via hwconf.c including the MII bus
- and PHY driver.
- There is backward compatibility with the END TSEC driver and can be
- configured if necessary but not for SRIO which requires vxBus to be included.
- FCS Version 2.0/0
- Released from Wind River for Workbench 2.4, VxWorks 6.2
- SRIO not supported for this first release, waiting until silicon works with
- a JTAG workaround during reset.
- ETSEC - enhanced features such as checksum offload not supported until the
- next release. Only standard TSEC features supported for now.
- PCI Express not supported yet. MSI unsupported.
- This BSP will move to the VXBUS infrastructure for drivers in vxWorks 6.3
- which include rapidIO and ETSEC. There are already changes in the BSP to
- support this which may not make alot of sense at this time. This means
- anyone wanting the additional functionality should expect to migrate to
- vxWorks 6.3.
- L2 cache will require modification to support rev2 silicon.
- Expect this to be done in the vxWorks 6.3 verison of the BSP.
- EAR Version 2.0/0
- Issues:
- Only Rev1.1 silicon supported
- VxWorks bootrom may not always run properly after power-on reset or HRESET.
- This is due to MPC8548 errata GEN3 which affects any silicon prior to rev
- 2.0. Refer to the "Freescale Device Errata for the MPC8548E PowerQUICC III".
- SRIO:
- Has not yet been tested on SBC8548.
- Requires GEN6 pll workaround via JTAG. TIPC_SM/SM END is working.
- Require addition of smUtilLib.o to MACH_EXTRA - should be temporary.
- PCI-Express:
- Has not yet been tested on SBC8548.
- PCI2:
- Not supported. Only the single 64-bit PCI1 interface is available on the SBC8548.
- Security Engine:
- Partially tested security engine drivers for SEC2.0 may still be issues.
- Additional features SEC2.1 not supported in present drivers.
- Only support 1GHz Core 400Mhz DDR to reduce configuration/initialization
- issues.
