kiwi SDR FPGA writing

:: FPGA spi mode write -> fpga.cpp  checking FPGA_INIT & FPGA_PGM ports. If they would not be worked, show " xxx panic".

FPGA_PGM :: OUTPOT PORT

FPGA_INIT :: INOUT PORT: So BBB or RPI confirms FPGA_INIT pin. Active or NOT? 

KiWi Voltage would be defective in case of RPI. It need Bigger current and higher voltage then BBB. I must confirm the electric regulator. Check voltage! A few times, Kiwi SDR with RPI!!  The rare case is very important. 

 

In case of showing "panic FPGA_PGM NOT active", appearing RPI can not initialize Kiwi FPGA.
