Hello Jan.

I'd like to connect another Spartan board to SD Card and write data through script SdcardTest.py

But I don't heve on-board PIC microcontroller. Could I use the FTDI USB-JTAG convertor to link PC with SD Card?

Hi Jan,

I want to write and read data from a sd card, but with another FPGA (Arty). Could I use the same projects from Xula2? Would it work? Thank you

Here's the capture of a simulation of the SD test:

To progress the state machine, I ran the simulator in 1µs chunks and force-flipped the the busy, handshake and sclk signals when needed.
