can i use RL-FlashFs without nandflash controller in my mcu lpc1822?

Hi there, now i want to use RL-FlashFs to manage the nandflash on my board, however, the mcu i use ---lpc1822 does not have a nandflash controller and i access the nandflash by timing simulation, can i use the RL-FlashFs as well by adapting the driver routines ?

  • i have connected the mcu with the nandflash via GPIOs, and access the nandflash by timing simulation
    Have you ever asked the question why use on-chip timers when delays can be generated by software? or why use on-chip I2C communication registers when I2C communication can be done on GPIO too?
    if not, then you must find the answers to such question.
    and then i ask the question, why not use the dedicated EMC pins rather then using GPIOs?

  • Thank you for your answer, I have such a question because the circuit was not designed by me, and the designer did not realize that one day i would encounter such a problem. Anyway, thank you and i will try to redesign the circuit if the file system can not be applied under such a condition~

    wait before hitting the Panic button.
    just in case, if ur application can sufficiently handle the on-chip ram and hence there is no requirement of off-chip parallel RAM, and also if ur flash memory requirement are not much higher, instead of redesigning the board again, you can use SPI flash, if you have SPI connections.


    ...doesnt have an EMC (External Memory Controller) peripheral, then you can use SPI flash
