ble_app_uart_c on a custom board with NRF52832-QFAA-R7

Hello, I am working on a custom board with NRF52832-QFAA-R7 and trying to run ble_app_uart_c on it. I am using uVision 5.23.0.0

  1. The first trouble that I am facing is that I can't get the softdevice and the ble_app_uart_c programmed together. I am first using nRFgo Studio to program the softdevice, and I have tried with all of these: s132_nrf52_1.0.0-3.alpha, s132_nrf52_2.0.1, s132_nrf52_3.1.0, s132_nrf52_4.0.3, s132_nrf52_5.0.0-3.alpha without success - when trying to program the application later, I always get Error: Flash Download failed - "Cortex-M4" error. I am confused how to combine matching versions and to resolve this problem.

  2. When I only program the application without having the softdevice programmed, I can't get any sign of it start working (I am simply trying to run some LEDs) - could it be if the softdevice is not programmed the application could not even start?

I am working for first time with nRF52 products, therefore questions might be trivial, I didn't find the right information to resolve problems, however, will be grateful if receive some particular advice.
