[vishal]

Hello Sir,

I have developed a product on nRF52832 DK kit and using S132 soft device. I want to flash this same hex file into SparkFun nRF52832 using nRF52832 DK. But i use lots of tutorials but unable to flash. I connect following connection SparkFun to nRF52832 DK: Sparkfun GND connect to--> nRF52 DK GND detect with Common GND. in header PIN20 3.3V --------------------> VDD short with VRF SWD IO -----------------> SWD IO SWD CLK ----------------> SWD CLK Is it any wrong in above connection please give some reference tutorial step by step. Or any other eclipse setting do i need to change for flashing with external nRF52 please let me know. How i do to SparkFun into bootloader mode. I am using this link link text

Thanks and Regards, Vishal

Hi Vishal, have you already managed to flash the hex file to your nrf52832 DK without the connected sparkfun breakout board? Have you read through this link and implemented it on your nrf52832?

Thanks for your valuable reply, I have using Eclipse IDE and everything is working with nRF52832 DK board flashing and other also working good. my product is read sensor value and send to mobile apps UART using BLE. With above connection i am able to flash simply led blinky example into my sparkfun nRF52 board directly copy hex file and paste into Jlink connector. When i trying to flash my main develop code into sparkfun board with same copy and paste hex file. It does not give any error but still program is not working with sparkFun board. When i trying to search my BLE device in android mobile it not seeking. So please sir let me know to solve my issue i am confused while flasing my main program into sparkFun it not give any error but program is not working. Is it any way flashing into sparkfun nRF52 using eclipse IDE, Let me know sir asap..

Best Regards, Visahl

Hi @vishal. I saw you posted a similar question to this. Have you already tried talking to sparkfun support? I am not very familiar with their products, so I believe it might be best to ask them first. If they can't help you, I will happily help you further. :)
