Hi,
I am trying to use openFPGALoader to program two MachXO3LF Starter boards in daisy chain configuration using FTDI FT4232H. I am able to program the second board (the last one in the chain), but without success for the FPGA with the index 0. After some inspection, i am assuming that there some issues with the pollBusyFlag() method. I have carried out another test using 3 devices in daisy chain and i was able to program the last device in the chain. Also to eliminate any hardware related issues, I have tried the same setup with Lattice diamond and it works fine.
