HSMC GPIO Daughter card.

Hi there,

I'll try this and will get back to you with the results.

I modified it to set all HSMC bidir and outputs high.

assign HSMC_TX_D_P = 'b11111111111111111;
assign HSMC_RX_D_P = 'b11111111111111111;
assign HSMC_TX_D_N = 'b11111111111111111;
assign HSMC_RX_D_N = 'b11111111111111111;
assign SMC_CLKIN0 = 1;
assign HSMC_CLKOUT_N1 = 1;
assign HSMC_CLKOUT_N2 = 1;
assign HSMC_CLKOUT_P1 = 1;
assign HSMC_CLKOUT_P2 = 1;
assign HSMC_CLKOUT0 = 1;

I have followed your steps for creating a project exactly and found that a lot of pins do change, but not trough the full range. For example HSMC_RX_D_n16 Switches between 1.6 and 2.6 volts. Maybe this is something in Quartus? I use Quartus II 64-Bit Version 15.0.0 Build 145 04/22/2015 SJ Web Edition, no patches installed. I run this on a Windows 8.1 system.

Does anyone have an idea on how to fix this?

Hi there,

I have done some measurements myself and have sent them to Terasic. They told me it might be damage to the IO of the FPGA. It might be an incorrect IO setting, but that was discussed before and is, for me, not the case. They think the latter more likely and they suggest I don't use the pins.
