I observed that the linker automatilcaaly splits the .text section into two sections: .text.1 and .text.2, when the code size exceeds approx. 50k. The problem with this is that...

    LukasRiedel
    Greetings everyone... I am developing the application for MSP430F2132 in CCE and one feature of the device should be the ability to upgrade its firmware during its life. The device consists of the MSP and radio chip, so the new firmware will come to the processor via radio packets. So I intend to...

    Hello! Just to preface this, I'm a bit new to MSP development, so some of my questions may seem a bit obvious or simplistic, for which I apologize in advance. Anyway, I'm attempting to develop an application which will allow for another chip interfacing with the MSP430 to be able to reprogram...
