I have a simple application (advertisement of the temperature) on the board with BGM13P32. I bought 16 pcs of BGMs. 12 of them work well. But with 4 items I have a problem. So far I have used BGM13P22 and there were no problems with running. I can detect BGM13P32 and program it (via Simplicity Commander), but it does not work. I turned on the debugger. The program hangs on:
// Enable HFXO oscillator, and wait for it to be stable
CMU_OscillatorEnable (cmuOsc_HFXO, true, true);
in initMcu ().
Is it possible to fix the error?
This would signal an issue with the HFXO soldering, the code is likely waiting for the HFXO to start but it doesn't.
So is it correct that you have assembled 16 of your own boards with the BGM13P32, and out of those 12 are working fine and 4 are showing this problem? I recommend that you raise a support ticket for our hardware support team to take a look, potentially sending a few boards to us for analysis.
thank you for answer. My employee opened a metal case module BGM13P32. We have found that one of the capacitors has a short circuit (see attach). After desoldering the module works correctly. We have repeated this procedure for 4 modules. They all work ok. I do not have a schematic diagram but comparing to the BRD4104A board the capacitor is at the power supply of the transmitter. Together with the coil, it creates a filter, so it's definitely important. Is the BGM13P32 schematic available? What is the value of the capacitor?
Can you clarify what you mean by short circuit? Did the capacitor have a short circuit due to soldering or did the capacitor burn due to some over voltage? Or do you mean that it was a resistor on the module by default?
Can you also clarify what the picture is showing exactly? It is not clear whether we see a removed component, a burned capacitor or a resistor on the picture.
Do you say that the module works fine when you remove the component, or does it work properly when you solder that component on the module again?
Can you send me a photo of the unmodified module that is working correctly? Removing the shield is not necessary, as there is a shield keepout area near that component.
The capacitor has a short circuit. I do not know the reason. In each modules it was the same capacitor (4 pcs BGM13P32).
The picture shows BGM13P32 (without metal shield) with removed capacitor. I marked the place where it was.
The four modules work fine when we remove the component. I think that it is capacitor but I do not know its value.
My employee removed the shield in only one module. In the next 3 pieces, the component was desoldered without removing the metal case. In the attachment picture with the module working correctly.
I have created a Salesforce case where we can discuss this issue further. Case number is 00192063.
what should I do? I have not used this option so far.
You can log into the Salesforce system via the following link:
After log in, you should find case 00192063 which I created from this forum post. You can either respond in the Salesforce system, but simply responding to my e-mail which I sent yesterday (no need to log in to Salesforce) will appear in the Salesforce system in the same way.
Let me know if you have any questions on this.
