|

I have observed what seem to be strange
|
||||
initialization problems with the ethernet
|
||||
driver:
|
||||
|
||||
I usually configure RTEMS networking by
|
||||
BOOTP (the problem has nothing to do with
|
||||
BOOTP but I just want to describe my
|
||||
environment). Sometimes (it can actually
|
||||
happen quite frequently, like 1 out of 4
|
||||
attempts but since yesterday when I decided
|
||||
to hunt this down more systematically
|
||||
the problem seems to have gone - typical!)
|
||||
networking fails to initialize properly:
|
||||
|
||||
BOOTP requests are sent (to the MAC),
|
||||
TX interrupts occur and the TX MIB
|
||||
counters increment - i.e., everything
|
||||
seems normal but no data can be seen on
|
||||
the wire. Also, even though we are on
|
||||
a quite busy network, the receiver
|
||||
doesn't see anything, i.e., 0 RX
|
||||
interrupts, RX MIB counters for broadcast
|
||||
packets remain steady at zero etc.
|
||||
In brief, everyting seems normal at the
|
||||
MAC and higher layers but no connection
|
||||
to the wire seems to be established.
|
||||
|
||||
Some further tests reveal (system under
|
||||
test is in the 'bad' state):
|
||||
1 communication with the BCM5461 PHY
|
||||
is normal. Registers can be read/written
|
||||
and everything seems normal. In particular,
|
||||
the link status is reported OK: disconnect
|
||||
the cable and MII - BMSR bit 1<<2 is clear,
|
||||
reconnect the cable and BMSR[2] is set.
|
||||
Restart autoneg, the link goes and comes
|
||||
back after a short while.
|
||||
2 setting the loopback bit in the TSEC's
|
||||
MACCFG1 register correctly feeds packets
|
||||
back into the RX, RX MIB counters now
|
||||
increment and indicate data flow.
|
||||
There are RX interrupts and all indicates
|
||||
(I haven't actually looked at RX packet
|
||||
data) that the RX would work normally.
|
||||
After switching MACCFG1[LOOP_BACK] off
|
||||
no RX traffic can be seen anymore.
|
||||
3 resetting the PHY (BMCR = 0x8000) and/or
|
||||
restarting autoneg (BMCR = 0x1200) seems
|
||||
to perform the desired action (registers
|
||||
take on expected values) but still no luck
|
||||
with communication all the way through
|
||||
to the wire.
|
||||
|
||||
Especially point 2 seems to indicate that
|
||||
the problem is likely to be between the
|
||||
wire and the MAC somewhere but re-setting
|
||||
the PHY doesn't change things. Analysis is
|
||||
much complicated by the fact that there
|
||||
is no documentation on the BCM5461 chip
|
||||
available.
|
||||
|
||||
Noteworthy is also that if the system
|
||||
initializes OK then it continues to work
|
||||
normally; if initialization fails then
|
||||
only resetting the board and restarting
|
||||
helps.
|
||||
|
||||
I wanted to test if it makes a difference
|
||||
if MotLoad used the chip prior to RTEMS
|
||||
being booted (in case MotLoad did some
|
||||
magic step during initialization) but
|
||||
before I could really test this the
|
||||
problem went away.
|
||||
|
||||
Big Mystery...

Some information about this BSP
|
||||
================================
|
||||
|
||||
ACKNOWLEDGEMENTS
|
||||
----------------
|
||||
Acknowledgements:
|
||||
|
||||
Valuable information was obtained from the following drivers
|
||||
|
||||
linux: (BCM54xx) Maciej W. Rozycki, Amy Fong.
|
||||
|
||||
This BSP also builds on top of the work of others who have contributed
|
||||
to similar RTEMS (powerpc) BSPs, most notably Eric Valette, Eric Norum
|
||||
and others.
|
||||
|
||||
This BSP was produced by the Stanford Linear Accelerator Center,
|
||||
Stanford University under contract with the US Department of Energy.

HARDWARE SUPPORT
|
||||
===============
|
||||
(some of the headers mentioned below contain more
|
||||
detailed information)
|
||||
|
||||
NOTE: The BSP supports the mvme3100 board.
|
||||
|
||||
CONSOLE: 2 serial devices, UART driver from 'shared' - no surprises
|
||||
("/dev/ttyS0", [="/dev/console"], "/dev/ttyS1"). (Only
|
||||
/dev/ttyS0 is accessible from the front panel.)
|
||||
|
||||
CLOCK: Decrementer, same as other PPC BSPs. (FIXME: a openpic timer
|
||||
could be used.) The bookE decrementer is slightly different
|
||||
from the classic PPC decrementer but the differences are
|
||||
hidden from the user.
|
||||
|
||||
PIC (interrupt controller) (bsp/irq.h): OpenPIC integrated with
|
||||
the MPC8540. (see also: bsp/openpic.h).
|
||||
|
||||
PCI (bsp/pci.h):
|
||||
In addition to rtems' PCI API, a call is available to scan
|
||||
all devices executing a user callback on each device.
|
||||
BSP_pciConfigDump() is a convenience wrapper dumping essential
|
||||
information (IDs, BAs, IRQ pin/line) to the console or a file.
|
||||
|
||||
MEMORY MAP: MotLoad; all addresses (MEM + I/O) read from PCI config. space
|
||||
are CPU addresses. For sake of portability, drivers should still
|
||||
use the _IO_BASE, PCI_MEM_BASE, PCI_DRAM_OFFSET constants.
|
||||
|
||||
NVRAM: No NVRAM.
|
||||
|
||||
FLASH (bsp/flashPgm.h): Routines to write flash. Highest level
|
||||
wrapper writes a file to flash.
|
||||
NOTE: Writing to flash is disabled by default;
|
||||
call BSP_flashWriteEnable().
|
||||
|
||||
I2C (bsp.h, rtems/libi2c.h, libchip/i2c-xxx.h): temp. sensor, eeprom
|
||||
and real-time clock (RTC) are available as device files (bsp.h);
|
||||
lower-level interface is provided by libi2c.h.
|
||||
|
||||
Available i2c devices are:
|
||||
|
||||
/dev/i2c0.vpd-eeprom
|
||||
/dev/i2c0.usr-eeprom
|
||||
/dev/i2c0.usr1-eeprom
|
||||
/dev/i2c0.ds1621
|
||||
/dev/i2c0.ds1621-raw
|
||||
/dev/i2c0.ds1375-raw
|
||||
|
||||
You can e.g., read the board temperature:
|
||||
fd = open("/dev/i2c0.ds1621",O_RDONLY)
|
||||
read(fd,&temp,1)
|
||||
close(fd);
|
||||
printf("Board Temp. is %idegC\n",(int)temp);
|
||||
|
||||
VME: (bsp/VME.h, bsp/vme_am_defs.h, bsp/VMEDMA.h).
|
||||
*always* use VME.h API, if possible; do *not* use chip driver
|
||||
(vmeTsi148.h) directly unless you know what you are
|
||||
doing (i.e., if you need specific features provided by the particular
|
||||
chip)
|
||||
|
||||
VMEConfig.h should not be used by applications as it makes them
|
||||
dependent on BSP internals. VMEConfig.h is intended to be used
|
||||
by BSP designers only.
|
||||
|
||||
VME interrupt priorities: the VME bridge(s) do not implement
|
||||
priorities in hardware.
|
||||
However, on the 3100 multiple physical interrupt
|
||||
lines/wires connect the VME bridge to the PIC. Hence, it is possible
|
||||
to assign the different wires different priorities at the PIC
|
||||
(see bsp/openpic.h) and to route VME interrupts to different
|
||||
wires according to their priority.
|
||||
You need to call driver specific routines
|
||||
for this (vmeXXXIntRoute()), however (for driver-specific API
|
||||
consult bsp/vmeTsi148.h).
|
||||
|
||||
For VME DMA *always* use the bsp/VMEDMA.h API. DO NOT use
|
||||
chip-specific features. Applications written using the bsp/VMEDMA.h
|
||||
API are portable between the UniverseII and the Tsi148.
|
||||
|
||||
HARDWARE TIMERS: (bsp/openpic.h). Programmable general-purpose
|
||||
timers. Routines are provided to setup, start and stop
|
||||
GPTs. The setup routine allows for specifying single-shot or periodic
|
||||
mode and dispatches a user ISR when the GPT expires.
|
||||
|
||||
NETWORK: (bsp/if_tsec_pub.h). In addition to the standard bsdnet
|
||||
'attach' function the driver offers a low-level API that
|
||||
can be used to implement alternate communication links
|
||||
which are totally decoupled from BSDNET.
|
||||
|
||||
Consult 'KNOWN_PROBLEMS'.
|
||||
|
||||
VPD: (bsp/vpd.h). The board's VPD (vital-product-data such as S/N,
|
||||
MAC addresses and so forth) can be retrieved.
|
||||
|
||||
BOOTING: BSP has a relocator-header. Clear MSR and jump to the first
|
||||
instruction in the binary. R3 and R4, if non-null, point to the
|
||||
start/end of an optional command line string that is copied into
|
||||
BSP_commandline_string. The BSP is compatible with 'netboot'.
|
||||
|
||||
Have fun.

|

* When it comes to interrupts the chip has two rather
|
||||
* annoying features:
|
||||
* 1 once an IRQ is pending, clearing the IMASK does not
|
||||
* de-assert the interrupt line.
|
||||
* 2 the chip has three physical interrupt lines even though
|
||||
* all events are reported in a single register. Rather
|
||||
* useless; we must hook 3 ISRs w/o any real benefit.
|
||||
* In fact, it makes our life a bit more difficult:
|
||||
*
|
||||
* Hence, for (1) we would have to mask interrupts at the PIC
|
||||
* but to re-enable them we would have to do that three times
|
||||
* because of (2).
|
||||
*
|
||||
* Therefore, we take the following approach:
|
||||
*
|
||||
* ISR masks all interrupts on the TSEC, acks/clears them
|
||||
* and stores the acked irqs in the device struct where
|
||||
* it is picked up by BSP_tsec_ack_irqs().
|
||||
* Since all interrupts are disabled until the daemon
|
||||
* re-enables them after calling BSP_tsec_ack_irqs()
|
||||
* no interrupts are lost.
|
||||
*
|
||||
* BUT: NO isr (including PHY isrs) MUST INTERRUPT ANY
|
||||
* OTHER ONE, i.e., they all must have the same
|
||||
* priority. Otherwise, integrity of the cached
|
||||
* irq_pending variable may be compromised.
