L1 is at 0xB401_0010
L2 is at 0xB401_0011
L3 is at 0xB401_0012
L4 is at 0xB401_0013
writing 0 into LED register turns it on
for example, to turn L4 on
./mmdump -a 0xb4010000 -o 0x13 -b 0x0
writing 1 into LED register turns it off
for example, to turn HBT off
./mmdump -a 0xb4010000 -o 0x0F -b 0x1
perform walking ones and walking zeroes test on HBT, L1, L2, L3 and L4
5.11 IRIG/SERIAL
PORT 7 (J3)
TX left
RX right
LED’s:
TX (top)
RX (bottom)
- bring-up IRIG-B fiber interface J3T and J3R
test procedure:
without fiber loopback cable both TX and RX LED's are off
./setup_all_ports.sh
# set IRIG_BUS signal high
./mmdump -a 0xb4020000 -o 0x00 -b 0x08
# fiber TX = IRIG_BUS
./mmdump -a 0xb4020000 -o 0x01 -b 0x02
observe TX/top LED is on
observe RX/bottom LED is off
plug in the loopback cable
observe TX/top LED is on
observe RX/bottom LED is on
./mmdump -a 0xb4020000 -o 0x00 -b 0x00
observe both LED's are off
# CH8 TX/RX
./mmdump -a 0xb4020000 -o 0x01 -b 0x03
./mmdump -a 0xb4020000 -o 0x06 -b 0x01
