CAN peripheral on Zynq with LVCMOS25

I am developing a Vivado project for a Zynq device. I have enabled CAN in the PS and attached those pins to on the FPGA pinout.



set_property IOSTANDARD LVCMOS25 [get_ports CAN_0_0_rx]
set_property IOSTANDARD LVCMOS25 [get_ports CAN_0_0_tx]
set_property PACKAGE_PIN Y15 [get_ports CAN_0_0_rx]
set_property PACKAGE_PIN W15 [get_ports CAN_0_0_tx]

When I transmit via CAN, on the oscilloscope frame is sent, but communication is not working between devices. I think that the problem I have is that bank is powered with 2,5V; because I have another project were CAN port pin are powered to 3,3V and it works fine.

The question is, is it possible to use CAN using pins from a bank powered to 2,5V?
