S.Mead reported PPG32 not working. D.Bishop confirmed - bad power. Found shorted capacitor. But only after unsoldering the Cyclone3 FPGA. FPGA replaced, bad power fixed. Board goes to K.O. for testing. |

testing the PPG32 by partial procedure at
http://www.triumf.info/wiki/DAQwiki/index.php/VME-NIMIO32#Procedure_for_newly_assembled_board_startup_and_test
sof file load ok, VME scan okey, NIM inputs and outputs okey, VME bit pattern test - no good. K.O.

PPG32 is broken - VME data bit 0x8 is stuck to 1. K.O.

D.B. fixed bad VME bit - bad resistor pack from FPGA to VME bus driver. K.O. |
