Hi Jace, No, still I am facing problem with this UART BSL. Now, I just left my custom BSL. And I am trying to communicate with the existing BSL(factory default) in the chip( MSP430F5255 ). I tried both Hardware BSL and software BSL for Invoking the BSL mode. And trying to communicate from BSL scripter.exe through MSP-FET430UIF debugger interface. Here I am using DVCC mode(By shorting DVIO with DVCC). Hardware Invoking: Used the connections which are mentioned in the MSP430F5255 datasheet for DVCC mode. Software Invoking: When I receive some character 'R' from UART, I am calling BSL address location as below: if(rec_ch == 'R') { //if(!(BIT2 & P4IN)) //{ debug_Transmit('R'); __bic_SR_register(GIE); ((void(*)())0x1000)(); //((void (*)(void))0x1000)(); //} } But, in both the cases I am not succeeded. And I am also tried to communicate from COM port of my PC to the controller through MAX3232 level shifter. But in scripter log I am getting access denied. Please suggest what are all the connections and pins required between the MSP-FET430UIF debugger and the MSP430F5255 controller for communicating with BSL of the controller from the BSL scripter.exe And also give me the exact procedure for this BSL communication from BSL scripter.exe.
