Fmc_continuous_clock_sync_only
WebI have also come across this using an 8080-style interface to an LCD through the FMC on an STM32F7. I thought that it must have something to do with the internal pipeline. I am observing that unless I insert a DSB, instead of seeing the expected five strobes of the write line (4 byte payload, 1 byte command), I see two - one when for each phase ... WebSTM32 Flexible Memory Controller (NOR Flash/PSRAM/SRAM controller). The FMC generates the appropriate signal timings to drive the following types of memories: * Asynchronous SRAM and ROM - 8 bits - 16 bits - 32 bits * PSRAM (Cellular RAM) - Asynchronous mode - Burst mode for synchronous accesses with configurable option to …

WebSTM32F429 external nor flash data not persistent using FSMC. Posted on June 12, 2024 at 14:24. Hi, I am using STM32F429ZET6 controller in my custom board. I have used JS28F00AM29EWHA Nor flash from micron.The interface between the controller and external nor is a parallel bus. I have made FMC_Init and GPIO_Init in the following way. WebsramHandle.Init.ContinuousClock = FMC_CONTINUOUS_CLOCK_SYNC_ASYNC; sramHandle.Init.WriteFifo = FMC_WRITE_FIFO_DISABLE; When I run it I get the following (Data in SRAM is 0xAAAA at all adresses).
