Hello, I'm a beginner for nRF51822, now my status is sticking on those SDK_11.0.0 BLE examples, while I could successfully running non-BLE (such as examples of bsp/uart).
Setup:
- Environment: Keil4
- Board: Custom board with 32MHz and LF 32.768kHz crystal circuity connected
- Programming tools: J-link with nRFgo Studio / Keil4
- Peer device: iPhone nRF Toolbox App
Problem:
-
Following tutorial "Getting started with nRF5 DK", I've erased chips, flashed SoftDevice S130 v2.0, and set ROM/RAM map on project, added header for custom board, then compile and flash \examples\ble_peripheral\ble_app_uart, and then I found there are no uart output, and even iPhone nRF Toolbox could not search any device with name Nordic_UART
-
Then I try to use debugger, and I found out that the program cannot run into the main(), but looping in address somewhere inside SoftDevice region
Tried:
-
Erase chips, without flashing SoftDevice, compile and flash examples\peripheral\uart to chips, I could successfully use TeraTerm to get the "Start" message and send "q" to quit.
-
Erase chips, flashed SoftDevice, set ROM/RAM address, compile and flash the above examples\peripheral\uart , I could still got positive result (I know this uart example won't use SoftDevice, this is a try for validating the new ROM/RAM settings are fine)
Can anyone help, what's wrong in my case and how to solve? Many thanks!
