MSP430F427: MSP430 Flasher error: unknown device

Part Number: MSP430F427
Other Parts Discussed in Thread: MSP-FET

Hi,

I'm trying to flash MSP430F427 from commands line via JTAG and at the end I've got Exit 16 and Error: unknown device.

Do I use wrong arguments or it's flasher bug? (by the way, CCS6,IAR  flashing works just fine).

Full log:

HOME: ~/MSPFlasher_1.3.16$ sudo ./MSP430Flasher -n MSP430F427 -w 1p_max_gp_210416.txt -m jtag -v  -z [VCC]

    Hi,

    there could be multiple reasons for your issues:

    1) Do you, by any chance, have multiple USB-FETs connected? It could be that your MSP Flasher connects to a different one by default which might not be connected to any target.
    2) Can you still flash your target through IAR/ CCS after trying to Flash via command line? Maybe sometime during the flashing process the JTAG-Fuse burned and stopped working.
    3) Please try running the MSPFlasher.exe without parameters. If everything's fine physically you should get a connection.

    Please let me know what the outcome of those tests is so that we can further narrow down where the issue comes from.

    Thanks and best regards,

    Hi Britta,

    Thank you for quick response.!

    As you suggest that,

     Can you still flash your target through IAR/ CCS after trying to Flash via command line? Maybe sometime during the flashing process the JTAG-Fuse burned and stopped working.

    Target flashed using MSP-FET Pro Lite. after wards tried program using MSPFlasher.

    it works fine.

    NOTE:- But i still i didn't get understand what was the reason. it would be great  if you explain the reason.

    Best,

    Ugra

    Hi Ugra,

    did I get it right that you re-tried flashing both using MSP-FET and the MSPFlasher using command line and it works now?

    I just asked you to try both ways again to make sure the JTAG-Fuse still works and that it's not causing the problem.

    Could you verify that your problem is solved?
    Unfortunately I don't know what caused the initial problem.

    Best regards,
    Britta
