The Belle II detector at the SuperKEKB e+ e- collider is the only Super Flavor Factory in the nearest future. Electromagnetic calorimeter (ECL) is one of the most important subsystems of Belle II. To cope with extremely high luminosity and severe background conditions it was decided to upgrade the end cap ECL and utilize pure CsI scintillation crystals. We report about development and study of the counter based on the pure CsI crystal and APD(s) (Hamamatsu S8664-55, S8664-1010).
