#
# Quirks in the DY-4 DMV177
#
# $Id$
#
JTAG and Caching
================
If data or code caching is enabled on certain revisions of the PPC603e,
then the JTAG emulator interface become disfunctional. You can not
debug using the emulator on these chip revisions. On certain revisions,
it is so bad that when code caching is enabled, you can not even
download code reliably to the board.
Caching and Peripherals
=======================
When caching is enabled, care must be exercised to insure that all
peripheral addresses are still uncached.
Exar 88681 Clock
================
This board uses a different clock for the Exar 88681 DUART than is
documented in the Exar manual or the original MC68681 manual. This
resulted in the need for the the mc68681 libchip driver to support
BSP specific baud rate tables and the development of a DMV177
specific baud rate table.
In the end, this all works but you have a very limited range of
useful baud rates on the 88681 ports compared to what would have
been supported had DY-4 just followed the Exar or Motorola manual.
SCC Addresses
=============
The full set of SCC addresses is not documented in the DY-4 manual
and they are not ordered as one would expect. Normally the four
SCC registers are ordered Control A, Data A, Control B, and Data B.
DY-4 orders them with B first.
This required extra time to debug.
SCV64 and the Foundation Firmware
=================================
DY-4 technical support did not offer code to determine which interrupt
sources were pending at the SCV64. They recommended calling into the
Foundation Firmware ROM monitor to figure this out. The Foundation
Firmware did not recognize enough interrupts on this board to be useful.
In the end, we gave up on their technical support's recommendation
and directly manipulated the SVC64. This is what we wanted to do in
the first place but we got no information from them to aid in this.
Luckily, the manual does document enough of DY-4's mapping of the specific
interrupt sources to make this work.
Z85C30 SCC Clock Speed
======================
The Z85C30 SCC can be factory configured for 10 Mhz or 2.4616 Mhz. Code
had to be added to dynamically determine which clock was installed.
The board we had used a 10 Mhz clock. No testing was done with a 2.4616 Mhz
clock.
P2 Octopus Cable
================
DY-4's P2 breakout is large and a bit unwieldy. It was difficult to
fight into the VME cage we used. The SCSI connector comes off the
side and is very stiff thus making it difficult to route around
anything in the back of the cage. We gave up on trying to use
it in the first few slots of OAR's cage.

Setting the Ethernet Hardware Address
=====================================
The hardware Ethernet address is not set at the factory. It is the
responsibility of the end-user to insure that it is set properly.
This file describes the standard procedure recommended by DY-4
technical support for setting this address. This procedure is
similar to that followed by VxWorks as documented in DY-4
Document Number #807885.
The hardware Ethernet address and OS configuration information
must be stored in the SEEPROM non-volatile memory of the
SVME/DMV-176/177. The Foundation Firmware (FFW) reserves the
first 256 bytes of the SEEPROM for its own use and the remaining
remaining 256 bytes are available for OS specific information.
Three bytes in the Serial EEPROM are used for the lowest three bytes
of the hardware Ethernet address These should be set to the serial
number of your SVME/DMV-176/177 card to ensure a unique Ethernet
address on your network. The three high bytes are hard coded in the
BSP and represent the vendor-specific Ethernet codes (0x00, 0x80, 0x7F).
Together these six bytes form the target's Ethernet address.
Address is of the form ...
NOTE: The serial number is found on the packaging (box) that the
board came in OR it is also located on the solder side of the board and
looks something like SERNO:XXXXXX. It can not be determined dynamically
by software.
Prior to using the Ethernet controller on the SVME/DMV-176/177 for the
first time, the Ethernet address bytes must be programmed into the
Serial EEPROM on the target card. The 'emm' (EEPROM Memory Modification)
command in the General Purpose Monitor (GPM) can be used to do this.
In this example we will assume that the serial number of the target card
is 123456.

# Cable information for the DY-4 DMV177

Background
==========
All serial cables described in this file were built using RJ-45 ribbon
cables which were plugged into DB-25 or DB-9 adapters wired as described.
Matching the colors of the wires in the shell is the easiest way to
make sure the cable is built properly.
The board is configured as follows:
- An MC68681 is the first two serial ports. These are RS-232 and may
be accessed via the front panel or the P2. The front panel connector
has both A and B serial ports on a single connector. DY-4 part number
"OBYC3ASSY901132-000 Rev-" brings these ports out to two DB-25
female connectors.
- The MC68681 serial ports are also accessible on the P2 connector.
DY-4 part number "OBYC3ASSY901080-004 Rev A" brings these out
to DB-9 female connectors. These were not used in this effort.
- A Z85C30 is used for the third and fourth serial ports. These are
RS-422 and may only be accessed via the P2 connector. These are
brought out to DB-25 male connectors. An RS-422 to RS-232 converter
was used to interface with these serial ports.

RS-422 Converter
================
An RS-422 to RS-232 converter from B&B Electronics was used to
adapt the RS-422 signals so they could be used with a normal
RS-232 serial port. Here is the information required to purchase
one of these:
RS-232/RS-422 Converter: Model 422LCON
Power Supply: Model 422PS

* sDeviceName This is the name of the device.

* however for DCE to DTE communication, no such routines
* should be necessary as RTS will be driven automatically
* when the transmitter is active.
* ulMargin The high water mark in the input buffer is set to the buffer
* size less ulMargin. Once this level is reached, the driver's
* flow control routine used to stop the remote transmitter will
* be called. This figure should be greater than or equal to
* the number of stages of FIFO between the transmitter and
* receiver.
* ulHysteresis After the high water mark specified by ulMargin has been
* reached, the driver's routine to re-start the remote
* transmitter will be called once the level in the input
* buffer has fallen by ulHysteresis bytes.
* pDeviceParams This contains either device specific data or a pointer to a
* device specific structure containing additional information
* not provided in this table.
* ulCtrlPort1 This is the primary control port number for the device. This
