Hi everyone,
We recently had to upgrade the operating system on the workstation for our
Avance NEO DNP spectrometer. The spectrometer was previously being run on
Topspin4.1.1 and the corresponding SpectrOS version on the EPU. In the
process of upgrading our workstation OS from CentOS7 to AlmaLinux, we installed
Topspin4.5.0 which was apparently not compatible with the SpectrOS that was
running on EPU. During the cf process Topspin tried upgrading the firmware
of one of BLABB1000 amplifiers, from which point the amplifier stopped working.
We tried software reset, power cycling multiple times, and also pressing the
reset button on the front panel of BLABB1000. The amplifier keeps flashing red
and green lights on the front panel, and on the amplifier webpage the following
error message is displayed: "Error code: 3758096394 Cannot perform operation
because of an internal error". On the log it says "000013 ERROR 00200:894 Failed
to open communication with the FPGA". The amplifier is being recognized during cf,
but due to this error the preamp routing cannot be detected and thus no acquisition
can be run. We managed to upgrade the SpectrOS to the version that works with
TS4.5.0, but that also didn't solve the issue. We also tried manually updating
the firmware with a file we received from Bruker, but again, no luck.
Bruker has said that there appears to be an issue with the FPGA board which
cannot be cleared and that the amplifier would need to be sent back for repair.
They also said that there could be an issue with boot-loader software and that
reprogramming it on a site visit might bring the amp back to life, but that
there is no guarantee that this would solve the issue. We were wondering if
anybody else had experienced a similar issue and found a fix. Both options
of fixes offered by Bruker are expensive and will result in even more
downtime, so would like to be avoided if at all possible.
Thanks,
Chris
