Hi,I'm working with DE0 development board. When I'm trying to compile my code i get the following message: "Error: Pin SFL:epromldr|altserial_flash_loader:altserial_flash_loader_component|\GEN_ASMI_TYPE_2:asmi_inst~ALTERA_DCLK is incompatible with I/O bank 1. It uses I/O standard 2.5 V, which has VCCIO requirement of 2.5V. That requirement is incompatible with bank's VCCIO setting or other output or bidirectional pins in the bank using VCCIO 3.3V". When I switched to"2.5V (default)" in the pin planner the problem will not appear. I what the I/O to be 3.3V LVTTL. how can I change that? If I delete the "flash loader" from my code the compilation should be o.k. (Of Corse, I need the flash loader in order to load my program after power up…) Idan
The pin is a part of the I/O bank.If u whant to apply these setting to one pin of the bank u need to apply it to the whole bank. This bank is set to 2,5V so u need to change all the pins to 3,3V
I guess, you have an incorrect setting of 2.5V somewhere in the device assignments. Because DE0 has an I/O voltage of 3.3V for all banks, there must be no 2.5V setting.
