I can repeat your problem on my ztex.

I've replaced 2 lines in transfer_data.c to make failures more visible:

	for(i = 0; i < 8; i++)
		printf("S[0][%d] = 0x%08x 0x%08x %s\n", i, received[i], sent[i], received[i] == sent[i] ? "ok": "<<< failure");

But for me, it segfaulted first several runs and then it fails on every run:

S[0][0] = 0xd1310ba6 0xd131f12c <<< failure
S[0][1] = 0x98dfb5ac 0x98dfb5ac ok
S[0][2] = 0x2ffd72db 0x2ffd72db ok
S[0][3] = 0xd01adfb7 0xd01adfb7 ok
S[0][4] = 0xb8e1afed 0xb8e1afed ok
S[0][5] = 0x6a267e96 0x6a267e96 ok
S[0][6] = 0xba7c9045 0xba7c9045 ok
S[0][7] = 0xf12c7f99 0xf12c7f99 ok

Also I noticed that only 1 led on board became black, so I think only
1 fpga chip got bitstream.

My commands:

ztex-experimental$ java -cp ../ztex/java/FWLoader/FWLoader.jar FWLoader -uf test_communication/intraffic.bit

ztex-experimental$ gcc transfer_data.c -lusb && ./a.out
