Hi!
I know that my problem is unsolvable, so my message is like a cry from the heart)
I've read so many posts about this problem. And any of solutions didn't help me.
I develop a device with MSP430F148. I use MSP430-JTAG-TINY-V2 to debug and IAR KickStart 5.60. At first I connected debugger with 4-wire jtag interface (and RST pin). When i tried to debug in IAR there was an error:
Could not find device (or device not supported)
Then i unconnected RST pin of microcontroller from jtag connector. After this debugger run. But from time to time i got an error:
Security fuse has been blown
I made two same boards with MSP430F148. With first one i got this error very seldom. But with the second one i got this error too often (debugger run in about 1 time from 20 attempts). And two days ago IAR started to give out my previous error (with unconnected RST pin):
Could not find device (or device not supported)
So, i saw many advices and tried it. But no success. The most popular solution is related with RST pin. I removed capacitor 2,2n, reduced the value of pull-up resistor, made button to reset the board (esspecially at the powering up the board). But nothing helped.
I tried many softwares like MSPFET, MSP OLIMEX PROGRAMMER, MSP430 Flasher. Each of them give me out now the same error - Could not find device (or device not supported).
There is an idea about programm code that not disables watchdog and microcontroller is always in "reset-cycle". But programm witch i wrote in flash of microcontroller is executing now.
I tried different drivers and dlls (MSP430.dll and OLIMEX.DLL), but nothing helped.
If you have any ideas please give me know
Thanks in advance!
