I am not an expert in real-time, so I would ask you to elaborate on what particularly makes nandsim not real-time? What are your requirements? Which nandsim operation/function/part has to be done in fixed time but it is not? Why do you think other pieces of kernel code are OK but nandsim is a bottleneck WRT to real-time? > Furthermore, there are some efforts to develop a (scaleable) real-time > capable flash file system? We develop UBIFS (see MTD web site) but we do not set real-time requirements. You are welcome to collaborate. --=20 Best regards, Artem Bityutskiy (=D0=91=D0=B8=D1=82=D1=8E=D1=86=D0=BA=D0=B8=D0=B9 =D0=90= =D1=80=D1=82=D1=91=D0=BC)
