I am trying to use the SD card of the DE10-Nano board for writing data in real-time.
I am using the IP named Altera_UP_SD_Card_Avalon_interface.
The problem arises when I try to connect the 4 pins of the IP to the physical Micro SD card socket.
I connect the four pins as written in the DE10-Nano user manual (https://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=&ved=2ahUKEwjNkLv-zJr9AhUNtKQKHaP-C5wQFnoECA8QAQ&url=https%3A%2F%2Fwww.terasic.com.tw%2Fcgi-bin%2Fpage%2Farchive_download.pl%3FLanguage%3DTaiwan%26No%3D1046%26FID%3D1c19d1d50e0ee9b21678e881004f6d81&usg=AOvVaw3fNmUCTp2a8PGm2lFNG1Sl
sd_card_b_SD_cmd=>PIN_D14,
sd_card_b_SD_dat=>PIN_C13,
sd_card_b_SD_dat3=>PIN_B9,
sd_card_o_SD_clock=>PIN_B8
and I have the following error:
Error (14566): The Fitter cannot place 4 periphery component(s) due to conflicts with existing constraints (4 pin(s)). Fix the errors described in the submessages, and then rerun the Fitter. The Intel FPGA Knowledge Database may also contain articles with information on how to resolve this periphery placement failure. Review the errors and then visit the Knowledge Database at https://www.altera.com/support/support-resources/knowledge-base/search.html and search for this specific error message number.
> Error (175020): The Fitter cannot place logic pin in region (55, 81) to (55, 81), to which it is constrained, because there are no valid locations in the region for logic of this type.
> Error (16234): No legal location could be found out of 1 considered location(s). Reasons why each location could not be used are summarized below:
> Error (184016): There were not enough single-ended bidirectional pin locations available (1 location affected)
How can I solve this problem?
Thank you very much.
