Dear Sir/ Madam
I am trying get my cyclone 3 development kit work with the in built flash. I have made a VHDL code, very basic, i would like to just get a simple read and write done before i do somthing big. I am get the following warnings, will this effect my talking to the FLASH, if so what can i do? Warning: Following 16 pins must use external clamping diodes. Info: Pin DQ[0] uses I/O standard 2.5 V at H3 Info: Pin DQ[1] uses I/O standard 2.5 V at D1 Info: Pin DQ[2] uses I/O standard 2.5 V at A8 Info: Pin DQ[3] uses I/O standard 2.5 V at B8 Info: Pin DQ[4] uses I/O standard 2.5 V at B7 Info: Pin DQ[5] uses I/O standard 2.5 V at C5 Info: Pin DQ[6] uses I/O standard 2.5 V at E8 Info: Pin DQ[7] uses I/O standard 2.5 V at A4 Info: Pin DQ[8] uses I/O standard 2.5 V at B4 Info: Pin DQ[9] uses I/O standard 2.5 V at E7 Info: Pin DQ[10] uses I/O standard 2.5 V at A3 Info: Pin DQ[11] uses I/O standard 2.5 V at B3 Info: Pin DQ[12] uses I/O standard 2.5 V at D5 Info: Pin DQ[13] uses I/O standard 2.5 V at B5 Info: Pin DQ[14] uses I/O standard 2.5 V at A5 Info: Pin DQ[15] uses I/O standard 2.5 V at B6 Warning: Following 16 pins have no output enable or a GND or VCC output enable - later changes to this connectivity may change fitting results Info: Pin DQ[0] has a permanently enabled output enable Info: Pin DQ[1] has a permanently enabled output enable Info: Pin DQ[2] has a permanently enabled output enable Info: Pin DQ[3] has a permanently enabled output enable Info: Pin DQ[4] has a permanently enabled output enable Info: Pin DQ[5] has a permanently enabled output enable Info: Pin DQ[6] has a permanently enabled output enable Info: Pin DQ[7] has a permanently enabled output enable Info: Pin DQ[8] has a permanently enabled output enable Info: Pin DQ[9] has a permanently enabled output enable Info: Pin DQ[10] has a permanently enabled output enable Info: Pin DQ[11] has a permanently enabled output enable Info: Pin DQ[12] has a permanently enabled output enable Info: Pin DQ[13] has a permanently enabled output enable Info: Pin DQ[14] has a permanently enabled output enable Info: Pin DQ[15] has a permanently enabled output enable Warning: Following 33 pins have nothing, GND, or VCC driving datain port -- changes to this connectivity may change fitting results Info: Pin A[0] has VCC driving its datain port Info: Pin A[1] has VCC driving its datain port Info: Pin A[2] has VCC driving its datain port Info: Pin A[3] has VCC driving its datain port Info: Pin A[4] has VCC driving its datain port Info: Pin A[5] has VCC driving its datain port Info: Pin A[6] has VCC driving its datain port Info: Pin A[7] has VCC driving its datain port Info: Pin A[8] has VCC driving its datain port Info: Pin A[9] has VCC driving its datain port Info: Pin A[10] has VCC driving its datain port Info: Pin A[11] has VCC driving its datain port Info: Pin A[12] has VCC driving its datain port Info: Pin A[13] has VCC driving its datain port Info: Pin A[14] has VCC driving its datain port Info: Pin A[15] has VCC driving its datain port Info: Pin A[16] has VCC driving its datain port Info: Pin A[17] has VCC driving its datain port Info: Pin A[18] has VCC driving its datain port Info: Pin A[19] has VCC driving its datain port Info: Pin A[20] has VCC driving its datain port Info: Pin A[21] has VCC driving its datain port Info: Pin A[22] has VCC driving its datain port Info: Pin A[23] has VCC driving its datain port Info: Pin A[24] has VCC driving its datain port Info: Pin wt has GND driving its datain port Info: Pin DQ[9] has GND driving its datain port Info: Pin DQ[10] has GND driving its datain port Info: Pin DQ[11] has GND driving its datain port Info: Pin DQ[12] has GND driving its datain port Info: Pin DQ[13] has GND driving its datain port Info: Pin DQ[14] has GND driving its datain port Info: Pin DQ[15] has GND driving its datain port Thank You Regards Dharmesh Joshi
