  1. I am using zybo and block design flow to connect xadc ip to my system. But, the xadc is not giving out any info acquired from the outside. One forum mentioned that in case there is no instantiation xadc read internal voltage or temp. So I checked the wrapper and there is no instantiation of xadc. I am feeding the xadc with 100mhz clock. Should I change it? P. S; if I posted in the wrong forum please move my post. Thank you in advance for any help.
  2. Thank you for your timely response . Now, I want to measure DC voltage.what if I feed in a voltage greater Than 1 volts? Another question: what is the purpose of VCC and GND in XADC pmod(the last 4 pins)? Do their power up the ADC? Thanks.
  3. They said the same thing. 😂 Anyways what is the output pin of the xadc. Which gives out digital values. Help me out. Please.
  4. Hi, I am trying to interface XADC on Zybo with xillyubus to measure external analog values.Rest of the design is working okay with a counter.My Question is how do i connect XADC with the xillybus Ip Core. any help is appreciated thank you
  5. Hi, I have formatted the card with FAT32 with 32 kb chunk size. And yes I have already used different sd cards. I was thinking about using linux on fpga. Should I? Can you point me in that direction? Thank you for your time.
  6. Hello, After your help the last time i was able to mount and create a file system but now my code is stuck on writing to sd card. The error it gives is "(1) A hard error occurred in the low level disk I/O layer */". i have attached my code,any help is appreciated. datalogging_v1.txt
  7. Yes,I have used a different sd card. I think my problem is in the hardware design. But I don't know what.
  8. I found the error. It says physical drive cannot work. But my sd card is working fine.
  9. Hi, He is using the same code I am. The problem is my fpga fails to create volume on the sdcard. I have tried a different fpga with different sd cards.i don't know what I am doing wrong. Help!!! I am working on data logging to sd card.

  11. Hi, I am new to fpga. I am trying to read/write from sd card zusing the zybo zynq 7000 and I found the Xillfs example. For some reason the mkfs function always fails. I don't know if there is a problem with my design? I have enabled the sd0 in zynq processing system. Is the something else I should do? Any help is appreciated.
