Hi,everyone I have trouble in debugging the "device_firmware_updates" example. Here is my development environment: Keil-MDK :v5.1.0.0 and v5.11.0.0(an other PC). SDK: 4.4.2. S110: 5.2.1. nrfgo studio: 1.17.0. chip: nRF51822 QFAAG00.
when I download code to the chip ,Keil will generate an error:"ERROR: Cannot connect to the nRF51 device."
but the nrfgo studio shows the bootloader has been flashed to the memory.
And i can't debug the project.
If anyone know how to fix this, tell me, please!
