hardfault, please suggest, thanks.

Question

Hi,

I got the following hardfault when running sdk 14.2, nrf52832. Since the address shows it locates in softdevice...I do not know why. May you please give me tip? Thanks!

Environment: Win10 professional. Jlink 6.22g

I am using a custom board, which runs sdk 12.2 quite well and migrating to sdk 14.2.

Hi 
 haakonsh, thanks for your reply. I guess I found the reason. The stack size is small. By increasing the stack size from 2048 to 4096, the problem is resolved.
