CC2640R2F: the MCU not working

Hi,

Did you see Supply Voltage on the Power Supply pins (VDDS, VDDR and DCDC_SW Pins) ? If ther eis no voltage on the Pins then there might be a problem with your PS circuit.

Could you please post your Schematic in PDF form for review?

Thanks,

PM

it is all perfect

Hi,

How many boards you tested? All boards behave the same?

Did you assemble the board manually or Machine?

Did you check the Orientation of the Chip? (Pin-1 Location)? 

Could you please post the Schematic in PDF?

Thanks,

PM

Hi,

i have tested 3 boards so far it is achine soldered and the orientation is good schem.pdf

Hi,

OK, I will review your Schematic and provide you the comments ASAP. Please bare with us.

Do you have any out Launchpad?

Could you compare the Pin Voltages with the Pin voltages on the Launchpad ?

Would it be possible to interface your board to the Launchpad and control it from SmartRF Studio?

Thanks,

PM

yes i have launchpad and i already done the coparision for your inforation i can flash it no proble but not working

Hi,

Could you be more specific what is not working means?

I recommend to use SmartRF Studio and test the Radio.

You can use CW-Unmodulated to test the Tx Power and the Tx freq.

Thanks,

PM

Dear PM

not working that is mean the main MCU not working i have done simple software LED blinking and nothing happend

my step now to let the ain MCU work then i can move forward 

Hi,

What code you are using?

Is it from TI?

Thanks,

PM

i did it is working on Launchpad but on my board not

the code built with CCS

Hi,

Did you check the Crystal Oscillator (24MHz) running on your board?

I recommend  you to interface your board with Launchpad and use SmartRF Studio to check the performance. You can also turn ON/OFF the GPIOs from the SmartRF Studio.

I also recommend to use Example codes from our SDK.

Thanks,

PM

Dear PM

as I informed previously i want now the ain MCU to work so i removed the two crystals depending on the internal frequency. i will try to connect to sartRF and let you know 

one more thing i tried to connect the debugger gave me this error 

A router subpath could not be accessed. The board configuration file is probably incorrect. (Emulation package 8.2.0.00004) from CCS but if i want to flash the programm using flash programm 2 application can flash and connect

is it this one can give any sense

Hi PM

i connected to the smartRF studio the program can detect the chip normally but there is no pin controlling what i ment i cannot control the IO pins 

Hi,

Did you go to the IO Configuration?

If not, Click on the "Customize" button and it opens up Custom Target configuration. Then under IO Config tab, select the desired IO, Flip the State and press Apply. Then check the Voltage on the corresponding Pin.

Please make sure that the Target Selection comes up with the correct Chip in Custom Target configuration page.

If you already done this one and DIOs are not flipping the state then I don't know what else I can suggest.

You may swap the chips from the LP to your board and try.

Thanks,

PM

thanks PM 

yes for pin configration i have done but nothing 

Hi,

OK, you can Swap the chips from the  LP to your board and check.

Thanks,

PM

i a doing new board anually without connecting onther chips only mcu and powersupply

Hi,

OK, you can do that.

Would it be possible to isolate ( all the GPIOs) the Part from the other chips on the existing boards?

If it is possible then you can avoid assembling the board manually.

Thanks,

PM

hi

I have built another board manually with smartrf studio now i can controll the pins i tried dio16,17,18 but dio6 cannot control

another issue i flashed led blinking it blinks 4 ties and stopped

thanks

Hi,

I t seems a strange behavior.

Did you install the 24MHz Crystal. If not, could you please mount and try again?

Thanks,

PM
