    BMF055- Program halts on custom design

    Hello everyone,

    We had purchased the BMF055 shuttle board along with breakout board and tested it out. Once satisfied, we had tried to implement the same into our customized board which replicated the circuit details as mentioned in the BMF055 shuttle board.  But, after programming the BMF055 IC and starting the debugging process, the program gets stuck in the "gclk.c" file at while loop (Highlighted line in attachment). We have rechecked the schematic connections of our board with the BMF055 Shuttle board and there are no changes to be found. We are using Atmel Studio IDE and Atmel ICE debugger for our debugging of the BMF055 IC. The example program used by us is "BMF055_DATA_STREAM-atsamd20j18".

    Please support us in resolving this issue.

    Thanks & regards,

    Rajeev K Nair

    Hi,

    Thanks for your inquiry.

    It seems like BMF055 shuttle board works fine with your firmware, but you cannot program BMF055 that is soldered on your own PCB. Please check the soldering quality and let us know if all PCBs have the same issue or not.

    Please let us know which country you are located in so that our local FAE can support you further offline to be more efficient.

    Thanks.

    Hello,

    Thank you for your reply.

    Yes, we have checked all the PCBs with BMF055 IC; we faced the same issue in them all. We even replaced the IC in the shuttle board into our PCB and still there were no changes found. The The soldering quality was checked and found to be of good quality. 

    Our organization is named C-DAC Thiruvananthapuram (www.cdac.in), located in Vellayambalam, Thiruvananthapuram, Kerala, India. We hope that you could lop us with your local FAE for further support, which woud be highly appreciated.  

    Also, is it possible to share the BMF055 shuttle board layout with us? It would help us to compare with our custom PCB and resolve any errors that might have been created while doing our PCB.

    Thanks & regards,

    Rajeev
