returned from CERN as broken. I see this: when inserted into crate, "red" LED does not come up (FPGA did not configure), JTAG does not work (jtagconfig reports "broken jtag chain"), voltage regulator U20 has almost zero volts (good modules read +1.5V). K.O. |

Replaced VREG U20 with LT1584CT, tested voltages OK, test_vf48 not okey. K.O.

Does not run 212-KO4 firmware - has "reset problem" with two frontends. 212-20-KO4-ALPHA runs fine.
K.O.
