HI,
I am using nRF51822 by Keil compiler. I found if it was programmed with boot loader nrf51422_xxac_s130.hex
by nRFGo Studio.
Then if download user code by Keil, it cannot run anymore. But if upload a zipped user code through DFU with priv.pem key, then it works.
use : Softdevie : S130, SDK V12.3
user code ROM1 is 0x1B000, length : 0x1F000 iRAM is 0x20001FE8 and length : 0x2018.
If bootloader is not programmed, user code can upload through Keil and can run step by step debugging too.
Any idea what is wrong?
Thanks!
Martin
