Hi

I was programming and debugging code on a MSP430FR5736
over the past few days and then
this morning started again and found that I got the message that security
fuse flown or device not recognised. In the log it said security fuse blown.
I have looked back through previous post but could find nothing that helped.
I am using MSP-430UIF and IAR assembler. I have a MSP-TS430PW28
board and then my target board. I do
not have an external power supply. I have check continuity between the
TS430PW28 and the MCU and all is fine. I am using SBW to program. I erase
main memory only, but have also tried erasing info memory as well. I have
tried a number of boards. It seems they program the first time but not the
second. It is as though I am blowing the fuse, or creating a condition that
simulates this. I have 3.28V on Vcc. I have no shorts between any of the 4
pins. I have a pull up resistor for RST.

Any suggestions would be appreciated as I do not want to blow up any more!

Thanks

Peter

I am using IAR 5.6. I have been using it for a few weeks without any
problems. I am fairly certain it is something I have done but cannot see
what.

I used IAR 5.5 and I had problem with 5635, 5437A blown fuse (once in a while)... then TI guy told me to use 5.4, or 5.3. I use IAR 5.3 and never have any trouble again. I realy don't know why, but the TI guy said the fuse address is in the flash area (ofcourse it is), I do not remember what address, but when we erase flash, somehow we erase the fuse address.   Try using IAR 5.3, 5.2, 5.1 to burn.

Hi Anthony.

I tried this and it worked on 1 board but not the other 3. I guess these
ones really do have their fuses blown.
