I have a tutorial for the SLS SD/emmc card open coreso far i have populated all the pins but one... it is called fpga_reset_n but also reffered to in the top level verilog file as being pll_reset, what should i tie it to ? is is an input does the fpga reset when it is pulled to a binary 1 or does it reset when it is dropped to a binary 0. and if it is binary 0 can i connect it to VCC on the pin planner without any problems ? thanks !
Hi chasemayer2,First of all,I am sorry for any inconvenience caused to you. fpga_reset_n is active low signal.While pll_reset is active high. You can provide ground to pll_reset signal or you can use ~fpga_reset_n. You can download reference design from the following link https://cloud.altera.com/devstore/platform/15.1.0/usb-sd-card-mass-storage-design/ If you still have any doubt you can contact us at firstname.lastname@example.org. Waiting for your positive feedback Thanks, Krupesh
ok thanks ! you guys have been so helpful so far, i really appreciate the good work you guys put into the tutorial i am reading. i will email you guys if i have any more problems. by the way the board i am using the BEMICROMAX 10 from arrow, has no extra ground pins, will any old ground do ? I am having to power the sd card from a seperate battery pack and regulator.
