Pulpissimo bitstream generation.
#1
Hello,

I got the following errors during bitstream generation for genesys2 board.

Code:
open_run: Time (s): cpu = 00:00:12 ; elapsed = 00:00:19 . Memory (MB): peak = 7121.617 ; gain = 0.000 ; free physical = 3356 ; free virtual = 8201

make: *** [genesys2] Error 1

Even the console shows error, the .bit file is generated. I loaded the .bit file to genesys2 board and try to read and write in the memory with the plpbridge. Which didn't work.

Code:
$ plpbridge --chip=pulpissimo --cable=ftdi@digilent write --addr=0x1c000000 --size=32 --value=0x12345678
Found ftdi device i:0x403:0x6010:0

$ plpbridge --chip=pulpissimo --cable=ftdi@digilent read --addr=0x1c000000 --size=32

I also tried to communicate with RISC-V debug module with openOCD. Got the following output.

Could you please point out what am i missing here ?
