I would like to ask the experts: how can I partition about 4MB of the built-in NOR16M memory on the Huangshan Pai SF32LB52-UP for data storage? Because there are too many sensors and the TF card cannot be inserted, and now a lot of sensor data needs to run offline on its own without being constantly connected to the serial port. I have tried many methods, but it seems I can only read and cannot write. Additionally, does anyone have a detailed explanation of each function in the menuconfig configuration interface for this Huangshan Pai device?
