    Hi Guilermo,

    to check how read and write the memory for the MCU you should check the board schematic.

    Jtag could be accessible or not on pcb.

    Sometime other ways than jtag are used to flash and read memory on production units (uart, can etc).

    In this case you should know the communication port and the communication protocol

    If Jtag is accessible purchase spc5-udestk (full license version because your MCU do have 1.5Mbyte flash) is the right move.

    If memory could be read or not depends if the board manufacturer set or not the read protection flag on MCU memory array. This you should check with board manufacturer.

    Ciao
