Other Parts Discussed in Thread: UNIFLASH
Hi
I want to update firmware through USB. I am trying to invoke the BSL through software as suggested in the report http://www.ti.com/lit/an/slaa452c/slaa452c.pdf After the call to invoke BSL, the host software - the Visual Studio based GUI and the Python based Firmware Upgrader aren't detecting MSP430 as a HID. If I try to halt the programmer during debugging, I get the error message: "MSP430: Trouble Halting Target CPU: Internal error". But I can halt it after a while. If I try to read the memory at 0x1000 from the memory browser I can see all 0x3FFF. However, if I read the BSL memory from the command line tool MSPFlasher it appears to be fine and looks like this:

I am not being able to use BSLScripter as it is unable to open the HID device. I can't try UART-BSL as there is a problem with the UART on the PCB I am working on. In the document on using USB for firmware updates I did read something about the XT2 clock frequency setting but I haven't been able to look into that yet and will do so at the earliest.
Here is my code:
uint08 fInvokeBsl;
void main(void)
{
WDTCTL = WDTPW|WDTHOLD; // Stop WDT
USBKEYPID = 0x9628; // Unlock the USB registers
USBPWRCTL |= VBONIE; // Enable the VBUS-on interrupt
USBPHYCTL |= PUSEL;
USBCNF |= PUR_EN;
USBKEYPID = 0x9600; // Lock the USB registers
if(fInvokeBSL)
{
__disable_interrupt();
((void (*)())0x1000)();
fInvokeBSL = 0;
}
#pragma vector=USB_UBM_VECTOR // USB Interrupt Service Routine
__interrupt void iUsbInterruptHandler(void)
{
switch (__even_in_range(USBVECINT & 0x3f, USBVECINT_OUTPUT_ENDPOINT7))
{
case USBVECINT_PWR_VBUSOn:
fInvokeBSL = 1; // Set flag
//__bic_SR_register_on_exit(LPM3_bits); // Exit LPM3 when exiting the ISR.
break;
default:
break;
}
}
I have searched a lot on this issue including multiple threads on this forum but haven't been able to find a solution. Any help will be greatly appreciated. Please let me know if any other information is needed.
Thanks in advance
[Update:] Using Uniflash I programmed the BSL with values present in the attached file. Now on connecting the USB cable to my laptop and pausing the programmer, I get the message "Break at address '0x133C' with no debug information available, or outside of program code". I am able to view the disassembly code in the disassembly window.
