raspberry pi and ztex quad ?

[lukcoin]

I was wondering if anyone has gotten their ztex 1.15y quad running with a raspberry pi ? While I can find some references to BTCMiner and cgminer running on the pi all tests where done with a 1.15x instead of the quad fpga version. All get is :


With cgminer:

[2012-08-19 08:39:15] Started cgminer 2.7.0
[2012-08-19 08:39:15] Ztex check device: Failed to read ztex descriptor with err -9
[2012-08-19 08:39:15] prepare device: -9


With BTCMiner:

sudo java -cp ZtexBTCMiner-120703-ARM.jar BTCMiner -m p -f ztex_ufm1_15y.ihx -host  http://xxxx  -u yyyyy -p pas

old: bus=001  device=37 (`037')  ID=221a:100
   Manufacturer="ZTEX"  Product="USB-FPGA Module 1.15y (default)"    SerialNumber="04A36E10AF"
   productID=10.15.0.0  fwVer=0  ifVer=1
   FPGA unconfigured
Error: Device lost after uploading Firmware: No new device found

Both miners where run as root to avoid problems, so I assume this has something to do with the limited USB capability of the PI. But even a powered USB hub doesn't seem to help

Moved to an old asus eee pc for now can't have the ztex sitting idle

Try to upload firmware with eee-pc and then move board to RPi (don't disconnect power). That way it works for me

Seems like there is a new firmware for the pi will try this later when I find the time, switching computer is a bit of a nuisance
