Titanium Interfaces User Guide
gpio_rule_resource (error)
Message Resource name is empty
Resource is not a valid GPIO device instance
To fix You need to choose a valid resource.
gpio_rule_io_standard_bank (warning)
Message Mismatch voltage in I/O standard assignment in bank (<voltage>) and instance (<io_std>)
To fix You get this error when the voltage for the I/O bank does not match the I/O standard you
chose for the GPIO. Either change the I/O bank voltage or choose a compatible I/O standard.
gpio_rule_io_standard_compatibility (error)
Message I/O standard <value> is not supported in bank <bank>
To fix You get this error when you choose an I/O standard that is not supported in the bank. You
need to choose another I/O standard or pick a resource in another bank. See Titanium I/O
Banks on page 21 for the voltages supported in each bank and Types of GPIO on page 39 for
the I/O standards the GPIO support.
gpio_rule_drive_strength (error)
Message Valid drive strength for <iostd> is: <list>
To fix Choose the drive strength based on the recommendation in the message.
Message Invalid drive strength <value> for <iostd>. Check for valid I/O standard
To fix Confirm the drive strengths that are allowed for the I/O standard you want to use and then
change the setting accordingly.
gpio_rule_ddio_serial (error)
Message DDIO has to be none when serialization is enabled on both input and output
DDIO on input has to be none when deserialization is enabled
DDIO on output has to be none when serialization is enabled
To fix You cannot use DDIO and serialization or deserialization at the same time. Turn one of them
off.
gpio_rule_transmit_toggling (warning)
Message Bank <name> has <int> GPIO in inout/output mode that exceed max limit of <int> which can
result in LVTTL simultaneous switching noise
To fix If you use more than 6 HVIO pins as GPIO in output or inout mode in the same bank, it can
cause switching noise. Instead, use resources from another bank.
gpio_rule_serial_input_clk (error)
Message Input clock inversion is not allowed with deserialization enabled
To fix If you use deserialization, you cannot also invert the clock. Turn off the Inverted option.
