MSP-FET: MSP- FET430(Debug Probe) doesn't work

Hello Pubg,

Here are some things you can try to resolve the issue.

You mentioned installing the drivers but you can go through the steps listed in the MSP Debuggers User's Guide there are 4 different installation methods mentioned in the document (Section 4) . Also try programming an example code either through the CCS or CCS Cloud to see if the FET responds to the software. Section 5 contains a lot of specifics to the MSP-FET including the LED Signals and operation requirements; in the user's guide you have a last resort cold boot (Section 5.6.5.3)

Let us know if the problem persists.

Regards,

Luke

Hi Luke

Thank you for your reply.

First of all, I have another emulator msp-fet430uif in use, so I don't think this driver is a problem.
I have tried to download the program with IDE IAR ew430 7.12 before, which prompts "one of the connected MSP feeds / EZ feeds debuggers needs recovery", and then click OK, which prompts "only one msp-fet ez-fet debugger can be connected to your system due recovery."Then click OK. Repeat .
Does MSP FET conflict with msp-fet430uif?

I saw this "cold start" before.To execute this procedure, the msp-fet cover must be opened by unscrewing the four screens on its back,
I'm worried that if I do this, the problem still exists. Will TI replace this emulator?

Regards.

Hello Pubg,

The MSP-FET430UIF and the MSP-FET use different drivers so there could still be a potential driver issue. Please go ahead and try the cold-boot process. This was put into place to help recover MSP-FETs that have been potentially overwritten with incorrect firmware. We haven't seen any quality issues with the MSP-FET at this time so if the cold-boot doesn't work please keep us updated. As a last resort, reprogramming the MSP-FET with another programmer could also fix the issue.

Also, make sure to only have one debugger connected regardless of type, this includes launchpads.

Sincerely,

Luke

Hi Luke

Thank you for your reply.

I try the cold-boot process（slau647o.pdf  5.6.5.3 MSP-FET HID Cold Boot）.
I connect a jumper to j2 (for MSP-FET 2.0.6),Then Plug in the USB cable.The MSP-FET is stil not recognized by the device manager of the OS. Start the IDE （IAR ew430 7.12 or CCS 10.4）, it prompts “MSP430: Error: MSP-FET / eZ-FET recovery failed”.the "power" LED is always on and the "mode" LED is always off.

the problem still exists.What should I do next?
Is this emulator a quality problem? Ti's customer service center needs your confirmation, and then will give me another normal emulator. Will you? thank you.

Regards.
