Hi,
I am trying to design application specific board of TrxEB boards using MSP430F5438A and CC1120 at 434MHz. I have designed the PCB for some boards it is working fine, but for some others I am getting oscillator problem. I am using MC-306 (32.768MHz) oscillator with 15pF capacitors. The board is four layer and below the oscillator, there is a ground plane at a distance of 0.35mm. The ground plane is also there on top layer. I tried to debug in IAR Embedded Workbench and got the following results. The firmware is running on the TrxEB board and some of the boards successfully.
SFRIFG1 register has the problem. The values of OFIFG and VMAIFG bits remains the same as initial and the program is stuck in an indefinite loop (BD02, BD08, BD0C and BD10). The oscillator is the connected the same way in all boards. I am confused if the problem is with the oscillator, then why are the assembly instructions executing in the indefinite loop?
For more details please see the attached images.
