BLE off-chip OAD with CC2650 5XD

Other Parts Discussed in Thread: CC2650, CC2640

Hi,

I use CC2650 7ID chip to implement the off-chip OAD and it works very well.
Now I try to change 7ID to 5XD by change the PIN setting, the advertising and connection 
are normal as usual but OAD cannot be done. 
I guess it's the problem about BIM_ExtFlash, can you tell me how should I do?

    Hello Mr. Wei,

    There are no changed required to BIM_ExtFlash unless you have changed the pin mapping for SPI flash.

    For the App/Stack you need to make sure you use the correct board file with PIN and RF Front End & Bias settings. See the CC2640 SW Dev Guide (SWRU393) for more details.

    Hi,

    Make sure that you are using the correct board file, and that your external flash is connected to the correct SPI port since the Off-chip OAD interfaces with external flash chip via SPI.

    Hi JXS,

    Thank you for your reply.
    I've changed the pin mapping for SPI flash for 5XD chip in BIM_ExtFlash project, but it didn't work at all.
    For the App/Stack, I have included the 5XD board file and replaced CC26XXST_0120 with board.c of 5XD chip,
    is there any thing I have to do? RF front? Bias setting?

    thank you
    Wei

    Hell Wei,

    The RF settings are documented in the BLE SW Dev Guide (SWRU393).

    Since your problem is with OAD, I suggest using the JTAG debugger to step through the code. The OAD is all source, so there should be no issue with this method.
