    On the STM32F103E-Eval board there is a NOR flash device. The device supports the JEDEC CFI standard, therefore you can retrieve certain information from the device like number of pages, size, manufacturer.

    Does anyone know if you can retrieve all the data needed to configure the STM32's FSMC solely from CFI queries? You have to calculate wait states to set up the FSMC. Wait states are based on values obtained from the manufacture about the chip like tWP, tRC, and tWC. These values don't seem to be defined in the JEDEC CFI standard (JEP137B) or the CFI chapter in the NOR device's datasheet.

    Has anyone used CFI queries solely to set up the FSMC for NOR flash?

    thanks
