MSP430F5325: problem programming

Alessandro Di Paola

Part Number: MSP430F5325
Other Parts Discussed in Thread: MSP-FET

Good afternoon, we use about 10K pcs of TI MSP430F5325 on our products.

Sometimes happen we can’t program the microprocessor (about 30-40 times in a year) and we need to replace it and this is a big problem for us (expensive and leasure time).

After the replacement every thing works properly.

Let us know if there are some mistake on the electrical diagram or let us know if we can improve the programming phase.

For the program operation we use:

-Elprotronic sw FET-Pro430-Lite-3v41 and Usb Texas Inst MSP-FET FLASH EMULATION TOOL

In all our products we have designed a 9 poles connector for the programming operation as you can see in the electrical diagram PROGRAMMING CONNECTOR ELECTR DIAGR.pdf.

We have also designed a little pcb interface (INTERFACE ELECTRICAL DIAGRAM.pdf), useful to connect the 14 pole connector coming from MSP-FET FLASH EMULATION TOOL, the 9 poles connector of the device under programming and the power supply with a series fuse of 0.5 A. The power supply is always provided with an external 7,2 V Dc max on the J1 connector (see PROGRAMMING.JPG).

Thank you for your cooperation.

Hi Alessandro,

What voltage are you applying to pin 4 (VCC_TARGET) on the MSP-FET? Are you applying 7.2 V to that pin?

Nathan

Hi Nathan, no obviously no.

On pin 4 on MSP FET is connected 3,3V as described in the INTERFACE ELECTRICAL DIAGRAM.PDF, coming from the device under programming LDO regulator.

Many thanks

Alessandro

Hi Alessandro,

Are you seeing this happen on all devices? Or does this only occur with some of them?

Hi Nathan, as I wrote the problem occour only with some pieces, not all of them.

Alessandro,

are you programming in 4 wire mode or SpiBiWire?
Do you also reprogram the BSL area or use the JTAG lock signature to lock your devices?
When the part cannot be programmed anymore what does a normal IAR IDE reports?

Best regards,
Dietmar

Hello Alessandro,

Do you have the information that Dietmar requested? If no answer soon, I'll assume you have resolved your issue and will close this thread.

Hi Dietmar, here are some informations for you.

-we use 4 wire mode

-we reprogram the BSL area (we use ELPROTRONIC SOFTWARE).

Yesterday we have reprogrammed 40 devices. Theese devices were already programmed - already tested - ready for the shipment.

We succeed in reprogramming for 39 but one of them is fault, and we have replaced the microprocessor.

I attach the screenshoot of the warnings that appear with the Elprotronic sw (the segment address may change).

We hope in some advice in order to solve this problem.

Thankyou for your cooperation

Alessandro

Hello, sorry I was out of office.
I have answered today to Dietmar and the problem is not solved.

Alessandro,

ok when you reprogram the BSL do you also change the JTAG lock signature on 0x17FC?
The TXT image you program has the BSL content at the beginning right?
The issue in your screenshot seems to appear when you want to program main memory do you have also have code at addresses from 0x4400 to -0x4C00?
Is the reported segment alwasy the same.

I can imagine that the device might restart somehow between programmign the segments and the reporgrammed BSL which I think is a customized one is doing something strange.

Easy thing to check change the TXT image in way to program main memory before BSL and try again.
