Yes the compiler version was the issue. I used the compiler mentioned in the guide and it worked. Thanks

Please try to follow the guide.

We have many customers using SDK v14.2 on nRF52832 with no problem.

Hi Hung,

Thanks for the reply. Yes I used the mentioned guide to create the bootloader as well as the package. I didn't try the stock examples because I thought that the private key used in bootloader and example package will be different. I will check for assertion. Please confirm if you have DFU working in SDK 14.2 for nRF5832 on PCA10040. I am using arm gcc compiler version 7.2.1.

Thanks

Hi Remon,

Do you have the issue all the time when you try to do DFU ? Have you tried to test with the stock example in the SDK ? Could you check if there is any assertion on the bootloader side ?

Could you try to follow the guide here and let me know if you see the same issue ?
