We had this issue on BCU #1 and also on BCU #2

Description

Quando si configura le 2 schede HVC, qualcosa va storto e la scheda di sotto non si configura a modo. Ci se ne accorge perchè: 1) manca il tipico sibilino acutissimo che si sente quando tutto è a posto, 2) se sei nella shell ipython e dai un hvc.mirroSet() dà errore quando prova a cambiare il preshaper della 2 scheda. Sulla prima non ci sono errori. 3) Si sente un solo "toc" al mirrorSet.

Sembra che si scriva roba nella HVCboard[1] e lei non capisca. Se si rilegge la roba scritta, si trova altro.

La cosa non sembra dipendere dal nuovo software di configurazione: fa lo stesso anche con la versione vecchia a scripts.

Un power-cycle della BCU può talvolta risolvere.

EDIT LB 20150528 - THE EVENT BELOW IS SOMETHING ELSE. BcuNumber2 DOESNT SEEM TO BE AFFECTED BY THE HVC BOOT ISSUE
