OCSPI NOR Flash 2 module (MB1242)
8.6.1
Description
CN11 (left) and CN10 (right) allow connecting MB1242 modules. Different versions of this module support ICs part
numbers described in
. These connectors are connected to OCSPI2 interface of
STM32H7B3LIH6QU on the STM32H7B3I-EVAL Evaluation board.
WARNING: Due to board design, as OCSPI2 interface is “shared” with SDRAM and camera, it can only be tested
at low speed (Maximum: 50 MHz).
