README: Motorola MPC827X ADS (ads8272)
This file contains board-specific information for the Motorola MPC8272
ADS 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.
Additionally, the target board's reference entry (i.e., 'man ads827x')
provides board-specific information necessary to run VxWorks, and
should be read before this BSP is used.
PLEASE NOTE
-----------
When used with Tornado 2.2.1, this BSP requires modified versions of
several driver files. The relevant SPRs are SPR #94578 and SPR #94579.
The files are included in patch_SPR94578.zip, which is included in the
distribution for this BSP. Unzip and install this patch to obtain
the modified driver files.
The modified driver files should be included in a future Tornado 2.2.X
release and/or in a cumulative driver patch. If this BSP is used with
version of Tornado subsequent to 2.2.1 or with cumulative driver patch
number 2 or later, check whether the SPR modifications have already been
included before installing the patch included with this BSP.
The patch is not provided for vxWorks 6.x.
------------------------------------------------------------------------------
RELEASE 2.0/1
FCC SNOOP not initalized by default. Best performance when enabled.
Enable in config.h USER_D_CACHE_MODE (CACHE_COPYBACK | CACHE_SNOOP_ENABLE)
New bootrom required and MACH address needs to be updated via M command at
bootprompt.
RELEASE 2.0/0
No longer require patch for drivers with vxWorks6.x
Added support for extra BAT registers.
Use CPU_VARIANT _g2le which includes support for additional h/w breakpoints.
Fixed PHY issues with FCC and added support for Phy interrupt.
MAC address is now stored in pseudo NVRAM (flash).
startType is supported.
FCC now initialized with SNOOP enabled.
IMPORTANT:
Requires a new bootrom to be installed.
RELEASE 1.2/1
Added BSP support for the Security Engine interrupt.
Fixed SPRs
99953 : FCC Clk settings were causing some performance issues
***762 : bootrom has a problem with serial and configuring the boot parameters
RELEASE 1.2/0
SPR 93050 : Machine check for offboard address error
SPR 93051 : FCC transmit is very slow using blasterTCP
SPR 93052 : PCI Errata workaround doesn't work. IDMA done bit not being set, waiting for confirmation from Motorola.
