ECAL_8	impossible to have any ECS communication with the FEBs. No test performed with this CROC. Problem had been already seen with 2 different CROC v2 (backplane, SPECS bus problem, A board affecting the SPECS bus, reset bus ???)
ECAL_9	OK
ECAL_10	Data are dubious for several FEBs in synchronisation test. Noise tests are fine with usual time settings. CROC_28 has been replaced by CROC_24 in this crate. Still the synchronisation is dubious although the Noise test is fine. We observe that the board in slot 18 has a different Synchronisation plot from the others : the plot is shifted downward of at least 4ns. We never observed that at LAL or on the other crates. CROC_24 left in this crate
ECAL_11	board in slot 2 does not work properly. Board/Slot problem ??? This had been seen with CROC v2. Test of the CROC v4 was done by masking this board -> OK
ECAL_12	OK
ECAL_13	OK
ECAL_14	board in slot 18 (FEB number 217) provides wrong data in pattern mode (e.g. synchronisation test). Pedestal is fine and acquisition is correct in this mode. Synchronisation requires ram pattern. Even configuring the board 'by hand', I could not have correct ram patterns at the level of the CROC or looking at the spy ram of the sequencer. Notice that event headers are ok but data look corrupted. Same test done with FEB in slot 17 is ok
HCAL_22	OK
HCAL_23	OK
