MSP-FET430U64F: MSP-FET430 Red Led always on, no programming

Hello experts.

I'd like to ask if anyone have solved this issue:

Just when I connect my JTAG to my computer (or any computer) the green light turns on, and after 2 o 3 seconds, the red light turns on and stays on. When I try to program my microcontroller it always says: Unknown device.

Has anyone solved this issue?

Thank you in advance.

Hi,

According to this guide, table 7. https://www.ti.com/lit/ug/slau647o/slau647o.pdf

And if this still not helping. You can try the chapter 5.6.5.3 MSP-FET HID Cold Boot.

Best regards,

Hi Cash Hao11, I've already tried what you've suggested, but I'm still having the same issue. Is there any other option I could try?

Hi,

Sorry for the late response. Just back to the office due to the holiday here.

Maybe the issue is caused by the target board consumes too much current and the MSP-FET can not provide that current. You can try using an external voltage supplier for the target board for a workaround.

Best regards,
