Question
QUADSPI_BK1_IO3 issue in STM32G474 and STM32H753
Hello.
I am testing QSPI indirect mode using STM32G474 and STM32H753.
However, I found a weird operation of QUADSPI_BK1_IO3 pin.
Other pins are OK, but QUADSPI_BK1_IO3 is high states as in the redboxes.
It should be low states (0).
I have tested in STM32G474 and STM32H753.
Both are the same.
Plz let me know how to solve this issue.
