hey anyone got complied version of BFG for the S5 i can give a try , i can't figure out how to compile one.
hello! did you learn how to compile?
i tried v5.3 and v5.2 on my antminer s5 via SSH this way:

Code:
./configure --host=arm-angstrom-linux-gnueabi --enable-bitmain CFLAGS="-I$PWD/uthash/src -O0 -ggdb"
make AR=arm-angstrom-linux-gnueabi-ar
that gives me:

Code:

this compiled version looks like working, but compiled by me from Luke's git can't find the device.
i notice some strange.
in my case there is "Enabled..Drivers.....: antminer " but in developer's version "Drivers: bitmain"

please give me advice how to compile it.

i have a very old HD7790 cards
this piece of sheet Wink gives
Code:
ZEC: 12/13/16-02:29:46 - New job from zec-ru1.dwarfpool.com:3333
target: 0x001ffffc (diff: 2048H)
ZEC - Total Speed: 171.054 H/s, Total Shares: 10100, Rejected: 70, Time: 48:54
ZEC: GPU0 85.628 H/s, GPU1 85.425 H/s

works perfectly on miner v9.1, win7x64, for 2 days w/o any troubles....

https://en.wikipedia.org/wiki/Radeon_HD_7000_Series
1000mhz cpu, 1500 mhz memory and only 896 cpu units.
one card takes 40w and another one 60w. so i guess 200-250w per system with 2 this cards.
and you can compare power to rx480 with 1266 mhz cpu, 2250mhz memory and 2304 cpu units.

in all benchmarks (WPA (56/200mh/s), FAH (50/250 PPD) etc) each rx480 gives about 3.5-5pcs of hd7790.
if ETH i can't get the hashrate because my cards is 1 gb, but on the net there are digits like 5-6mh/sec, so its 31/6=5.1 times...
and only in ZEC each rx480 gives 200/85=2.3 pcs of hd7790.
so, this digit looks very sad, like theoretical 2304/896=2.57 pcs....
i don't know why hd7790 works so good to compare to rx480, may be a very good core code for hd7790, or may be a very bad code for rx480, or may be i'm totally wrong in all Smiley
