Hi Nordic-Team,
I've spent a while trying to figure this out but I couldn't. I need your help.
I want to load the S310 softdevice to the nRF51422 chip + the blinky example. Once I have that working I can move on to programming my BLE/ANT application. Loading the blinky at address 0 works without any problem.
Before I moved to the PCA10007 board, I tried the same steps with the nRF51822 USB dongle S110 and that works. I could load the S110 and the BLE UART example.
Edit: On the same chip. Same steps as below. The softdevice S110 + blinky works.
loadbin _build/ble_app_uart_s110.bin 00016000 (address for S110)
I can even add the code below and see "Yes" printed in my com.
sd_softdevice_is_enabled(&enabled);
if (enabled == NRF_SUCCESS)
simple_uart_putstring((const uint8_t*)"Yes ");
else
simple_uart_putstring((const uint8_t*)"No ");
All logs and things I tried:
Board is PCA10007, REV 3.0.0 Chip is NRF51422 QFAAE0 1347AA

Now if I try to load blinky back to address 0 it doesn't work. I need to erase all and load again for the LEDs to start blinking again.
With Python Mergehex
I also tried with python mergehex.
python /usr/local/bin/hexmerge.py s310/s310_nrf51422_1.0.0_softdevice.hex _build/blinky_xxaa.hex:0x20000: -o s310_blinky.hex
state is same as before when loading blinky.hex at 0x20000, but the LEDs don't blink.
