Hi,
Using Vivado 2014.2 I added/enabled the following additionnal communication ports:
UART0: MIO 14-15 LVCMOS33 (cannot be changed)
SPI0: EMIO
SPI1: EMIO
CAN0: MIO 10-11 LVCMOS33 (cannot be changed)
The ENET0, USB0, SD0 and UART1 are already enabled by default (default MicroZed configuration).
When generating the bitstream I get the following warning. I do not know what to do about it since pin allocation is fixed in Vivado. Do you have any ideas of what action to be taken in this case? What are the potential consequences?
[Place 30-12] An IO Bus FIXED_IO_mio with more than one IO standard is found. Components associated with this bus are:
t FIXED_IO_mio[53] of IOStandard LVCMOS18
FIXED_IO_mio[52] of IOStandard LVCMOS18
...
...
t FIXED_IO_mio[17] of IOStandard LVCMOS18
t FIXED_IO_mio[16] of IOStandard LVCMOS18
t FIXED_IO_mio[15] of IOStandard LVCMOS33
t FIXED_IO_mio[14] of IOStandard LVCMOS33
t ...
...
t and FIXED_IO_mio[0] of IOStandard LVCMOS33
Best Regards,
