Can the configuration bank on a cyclone 10 LP bet set at 1.8V when using Passive Serial configuration? Table 44 in the Core fabric handbook (c10lp-51003.pdf) suggests that the Configuration Voltage Standard is limited to 3.3V/3.0V/2.5V. A Host device would be driving the PS bus with 1.8V logic.
Apologize that it cannot be. Configuration bank (I/O banks 1, 6, 7, and
The reason is that it will affect the device bootup and configuration.
I've run into the same issue with using passive serial but trying to drive it with 1.8V from a host processor. Looking through the documentation and device pinout spreadsheet it's not clear to me why bank 7 also needs to be configured for 3.3/3.0/2.5V. Can you confirm that bank 7 requires 3.3/3.0/2.5V for PS configuration?
