DFU-OTA on bl653dvk with external flash and BLE

Hello Shikamaru,

Does the BL653dvk have external flash? It does not seem like it to me. Maybe you have attached an external flash yourself? Regardless, you need to configure the DTS/overlay file so it's set up to communicate with the external flash, like it's done by default in the nRF52840 DK board DTS file (uses mx25r64 external flash) and the nRF9160DK board DTS file (also uses mx25r64). Both of these DKs have an onboard external flash.

Best regards,

Simon

First step is to get it to build and if you don't succeed with this, please upload your project in a zipped file and I will take a look at it.

 yes,  I am able to build my project. However as soon as flashing am getting this error ,

E: Device id 00 00 00 does not match config 9d 40 13

it may be because it is not able to get the device binding of my external flash . i tried all the ways from forum as well unfortunately i didn't succeed in that. However an attaching my workspace here. Kindly guide me that what i am missing here 

Thanks and Regards,

Since it reads 000000, it seems like it is not in contact with the spi-flash. Could you check the output of build/zephyr/zephyr.dts and check if you have conected the spi flash correctly. Do you have a logic analyzer? Try reading the SPI pins and see if there is any activity.

Best regards,
