Adding FPGA sram hdl code and user space code Fixing some errors: LCD's pinout connector is swapped FPGA TDI SIGNAL must be routed to another pin (C14), right now is DQMH Remove R11 Check JZ4725 symbol's component (PORTD is wrong) Adding PB2 and PB3 wiring ADC's vref to external connector Adding power LED Adding CPU Led
