FMC EEPROM Check
In order to access the FMC EEPROM run the following command to display the VPD:
# e2fmc
−
v
−
W
Product Name [My Board Product Name]
Serial Number [My Board Serial Number]
Part Number []
If the output is the following:
Cannot read eeprom !
The FMC EEPROM could not be reach and some configurations must have failed.
4.4
FMC IOs Check
This check will be done with a loopback wired connector plugged on the FMC-SER0 front panel in order to verify
the IOs available on this front panel (FMC GPIOn and FMC TXn/RXn signals).
4.4.1
FMC GPIOn signals
Set odd FMC GPIOs (GPIO1,3,5,7,9) as outputs, others as inputs:
# gpio
−
c 9
−
s GPIO_Control
−
v 0x155
Set output GPIOs to 1:
# gpio
−
c 9
−
s GPIO_DataOut
−
v 0x155
Check the GPIO levels: all must be at level 1 (because they are outputs at level 1, or because thay are inputs
connected to the outputs).
# gpio
−
c 9
−
g GPIO_In
GPIO_In
−
> 0x000003FF
Set output GPIOs to 0:
# gpio
−
c 9
−
s GPIO_DataOut
−
v 0x0
Check the GPIO levels: all must be at level 0 (because they are outputs at level 0, or because thay are inputs
connected to the outputs)
# gpio
−
c 9
−
g GPIO_In
GPIO_In
−
> 0x00000000

Set even FMC GPIOs (GPIO2,4,6,8,10) as outputs, others as inputs:
# gpio
−
c 9
−
s GPIO_Control
−
