ble_app_uart_c on a custom board with NRF52832-QFAA-R7

[kont40]

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.

Merge SD and APP hex files (however if nRFgo Studio fails, it indicates some deeper problem I'm afraid - is the same sequence of steps working on nRF52 DK board?)

I don't have nRF52 DK board, working directly with the custom board. When erasing all from nRF go Studio the application code programs normally, all the errors are for overlapping softdevice and application code address spaces - I am using all the default project settings, however. I downloaded the ble_app_uart_c example project through the package installer of Keil, not sure if there is a newer version of it - all the latest versions of ble_app_uart_c example are for IAR only...
