I am using a Nexys 4 DDR board and want to use the microSD as an external memory to read from. right now:
I am using HDL only
Want to read from SD in SPI mode as a continues loop
Want to write to Micro SD offline via PC
I have an HDL code, and I am able to write to and then read-back from the SD inside the HDL correctly, but have no idea how a data file on my computer can be turned into something on SD that I can read properly in FPGA
Questions:
What file format am I supposed to use for the SD card? (FAT32? )
I wrote a random file to the SD using the HxD, when I initiate read in FPGA, I see data, but don't know what it is! Maybe I only need to figure the address for beginning of my data???
