TRF7960A EVM doesn't work after flashing TRF7960A C Code Samples

Hello,

I got an TRF7960A EVM which worked just fine.

But after downloading the TRF7960A C Code Samples
(ZIP, 153 KB) 309 views, 10 Aug 2011
without any changes to it the EVM stop working. Which means I get timeouts when I try to connect it to the GUI. And in stand_alone it stays in

while(irq_flag == 0x00)
{
} // wait for interrupt

How can I get back the original firmware (if possible plus code) ?

Hi Fabian,

Did you use an MSP-FET to program the EVM? Have you power cycled the EVM after programming it? What COM port is the EVM enumerating to?

Yes.

3 via uart

5 via MSP-FET

By UART do you mean the USB to UART bridge?

Such as:

Hi Fabian,

I flashed my TRF7960A EVM using an MSP-FET. Then power cycled it and connected the EVM to my computer via the USB to UART bridge. The GUI was able to find and connect to the EVM.

I flashed the EVM with both CCS and UniFlash from the code found here: www.ti.com/.../sloc251. For UniFlash, I opened the configuration file MSP430F2370.ccxml found in [install path]/trf7960A/ccxml. Then I loaded TRF7960A_06_2011.out file under [install path]/trf7960A/Debug and flashed it onto the board. For CCS, I imported the TRF7960A_06_2011 project and clicked the debug icon and ran the program. Before connecting to the GUI, I downloaded the USB driver for the TRF7960A. The location of the driver is listed in the 'USB driver directions.txt' file that comes in the .zip file with the GUI. I used the TRF7960A EVM GUI software found on the product page: www.ti.com/.../sloc134.

Did you follow the same steps/use the same files?

Thanks,
Caitlin

Thanks Caitlin,

I didn't know about the UniFlash software. Using that one (just like you discriped it) the EVM works and connects to the GUI.

But I repeaded it two times when I flash the same software with the CCS the EVM stops working (and works again when I use the UniFlash).

What am I doing wrong?

Is it normal that the firmware of the MSP-FET needs to be updated everytime I switch between the UniFlash and the CCS?

Hi Fabian,

What version of CCS are you using? Is it a free license?

I am prompted to update the MSP-FET firmware when I switch between UniFlash and CCS, too. My EVM connects to the GUI after the firmware update.

Thanks,

Caitlin

Yes, it's version 6.1.2 with a free license.

What compiler version are you using in CCS? (Right Click your project > Properties > General > Compiler version)

0 Fabian Assion over 7 years ago in reply to Caitlin Ramsey

It was TI v16.3.0.STS and now I switched to TI v4.4.5 and... it works :-) Thank you!

Can you tell me what's the problem with first compiler in combination with the EVM?

Or if there is a optimized compiler for this case?

Hi Fabian,

Hmmm, I'm not familiar with that compiler version actually, so hard to say what the difference is from that and TI v4.4.5.

My suspicion is that it isn't handling compatibility for older compilers correctly.

This code was built a long time ago, using TI v3.3.1 compiler... so my suspicion is that the TI v16.3.0.STS is not compatible with that old compiler but TI v4.4.5 is, so thus v4.4.5 works correctly.
