epc_rtcreg Read/write test for the real-time
clock (RTC) chip and NVRAM
Tests the RTC registers and a
small amount of NVRAM in
the RTC address-space
portion of the RTC chip. Tests
the following registers:
NVR_SEC
NVR_SECALRM
NVR_MI
NVR_MINALRM
NVR_HOUR
NVR_HOURALRM
NVR_WEEKDAY
NVR_DAY
NVR_MONTH
NVR_YEAR
NVRAM tested is in the range
0xE
– 0x3F.
epc_rtcinc RTC increment test Tests the ability of the RTC
chip to handle time-of-day
transitions. Sets the RTC to a
known time and date (last
second of the year), waits one
second, then checks to make
sure that the time and date
have changed correctly.
epc_rtcint RTC interrupt generation test Tests to make certain the RTC
can correctly generate Alarm,
Periodic, and Update
interrupts. Validates the path
from the RTC chip to the IP
board’s master CPU.
duart_loopback Dual Asynchronous
Receiver/Transmitter (DUART)
loopback test.
Attempts to configure and test
all available serial ports.
Performs loopback testing at
all baud rates for each port
tested. Normally, the test uses
the internal loopback, but if
you run it with the -e option,
the test assumes an external
loopback fixture is being used.
