Tool/software: TI C/C++ Compiler

when I tried to write to RF430FRL152H EVM using MSP FET, I am getting "Error connecting to the target: Unknown device". How can I fix this?

Hello Vijaya,

Are you using a TI example project imported into CCS?

Yes, "RF430FRL152H_NFC_Only_Project_NDEF_Support" project. Initially, it worked and I got NDEF message with the reader. When I tried to increase data in NDEF around 1896bytes (0x0768) I increased array contents and flashed. Now I can able to read with NFC reader, but the RF430xx EVM is not detecting through MSP-FET.

My colleague, Jayakrishnan also, contacting in another post regarding the same project,

Hello Vijaya,

Okay, when programming the device with MSP-FET again, did you change the switch settings on the EVM to be back to programming mode? I would check that first as that would be the most common issue for what you are describing.

switch S6 is in supply position while programming! is that you asking?

TI__Guru*** 135355 points

Hello Vijaya,

Yes, that is what I was asking - you'd be surprised how simple it is to forget that :)

I think I need to observe the issue for myself to help best and quickest, would it be possible for you to send me the project that caused the issue? If not the whole project, then at least the .out file. If I can replicate it on my EVM then I can try and recover it on my end and inform you on what needs to be done to do so.

How would I check whether the device is secured/locked or not? since the target is not detecting I tried to write .out file from uniflash, that one also interrupted.

Hello Vijaya,

What do you mean? Can you better clarify? Are you meaning the ISO15693 blocks being locked from NFC reading?

0 vijaya kumar77 over 7 years ago in reply to Ralph Jacobi

Prodigy 200 points

No, now also EVM is responding with NXP NFC reader app, I can read some content in an app, but programming is not happening with MSP-FET.

Hello Vijaya,

What version of CCS are you using? I am having trouble launching Debug with my CCS (not the same error as you are getting... rather a very odd one I've never seen before, so I suspect CCS versions may be at fault)

Code Composer Studio
Version: 8.0.0.00016

OS: Windows 10, v.10.0, x86 / win32

And I imported project

Thanks! I was using 7.2 so will try with 8.0. I am on Win 10 so that's consistent at least.

Hello Vijaya,

Okay that worked! CCS v8.0 built and downloaded the project just fine.

I did some tests read out the message with no issues, and then went to re-program and had no problem as well. I tried messing with a few settings to recreate your issue, and the only one which did was having Switch S6 set to the wrong position. Try toggling it back and forth and see if that helps.

If not, then get a DMM and try to confirm the switch connection is proper by checking for connectivity of the TP8 test point with the left pin of SV7 (Remove jumper), left with regard to orientation of board being with antenna at the very top. The pin on SV7 is closest to the FET debug port.

I am attaching an image for clarity too with TP8 circled in Yellow and the correct SV7 pin boxed in Green.

TP8 has connectivity with supply pin of switch S6. and switch S6 is proper when tested with DMM.

0 Ralph Jacobi over 7 years ago in reply to vijaya kumar77

TI__Guru*** 135355 points

Hello Vijaya,

TP8 will always have connectivity with the Supply Pin of the Switch S6, the key is testing that VDDB (which can be probed from the green boxed pin of the SV7 2 pin header) and TP8 (+1.5V rail) are tied together correctly by S6 operation. The VDDB pin will toggle between being connected to S6 Supply and not by the switch settings.

OK checked it, green boxed pin is in short with supply or battery as and when switch s6 is positioned respective positions.

Hello Vijaya,

Hmm... do you have a second EVM around? Can you try to replicate it with another board?

I am getting suspicious something has damaged that EVM somehow.

Can you send me a picture of the board so I can give it a visual once over?

If the issue doesn't repeat with a second board and/or if you don't have a second and I can see nothing out of place then you can use this post as proof for RMA of the EVM.

1. We don't have second EVM.

2. attached picture of my setup.

3. As in below image, I tried different erase options, but not worked. And in the green boxed message is saying device connection will not possible after device secured. When CCS flash failing, I tried Uniflash to write .out file but interrupted, will this cause any issue. If so how can I do check is security enabled? and how can I clear it. Now also EVM is responding to NFC reader app and getting without problems.

Hi Vijaya,

And just to be sure, you had only removed the jumper for doing the measurement test I referenced right? It was in place when the first failures occurred? I ask as I just tested without jumper w/ Switch set to S6 and it doesn't work like that either. So the jumper must be in place as well as having switch set to S6.

That the device works is curious... it might be worthwhile to probe out the voltage levels as well to see if the 1.5V rails is properly powered as well.

Regarding the Security box, I am not familiar with that at all. In any case, security features would have to be added very intentionally (like writing a JTAG password, but even then I don't think it's possible to fully secure the device like that box indicates with our FRL device), and if your firmware or CCS project did that then I would observe such an issue as well, so it can't be that, right?

1. Yes, the jumper wire is removed for connectivity testing only, it was there always, every debugging and during when I got the error too.

2. I will try to trace 1.5V rails, but the device is good in battery mode and when reading from NFC reader app from android mobile 'n' number of times. the device is responsive, readable but not writable! means 1.5v rails are working fine?

3. Regarding security box, If my firmware code flashed properly then no problems, but flashing was interrupted a couple of times with error and when used uniflash to write .out file also ended with the failed message. If my project is working and flashing with you (sent project file) normally, then in my case when interruptions occurred, does it locked/(something?) with my device?

Hi Vijaya,

I would need to ask another engineer who is out of office for today only about point 3... I am not sure if that could cause the device to be in an unrecoverable state. Stay tuned on that.

Thank you

0 Ralph Jacobi over 7 years ago in reply to vijaya kumar77

TI__Guru*** 135355 points

Hello Vijaya,

We looked into this more and the suspicion is that some error occurred which caused the JTAG Password register to get written into, enabling the password as a result. We don't have a means to recover from that when the password is unknown, and if that's what happened then the device has been bricked. Please submit for an RMA to get a new board.

Hello Ralph Jacobi,

Can you forward the same request to the concerned team (TI-Bangalore) for the faster replacement, If the extra board is available with them I will directly meet TI-Bangalore office, near to me, for the new board?

Hello Vijaya,

I don't know anyone in that group, and I don't really have a quick means to do that, sorry. If you get a purchase order number or something along those lines, I can ask a general support team if it's possible to expedite it though.
