SPI peripheral doesn't work if the code is compiled in Ubuntu but works in Windows

Hi,

I'm working on a BLE project with NCS v2.1.1 running on nRF52832. The project includes several I2C and SPI sensors. If I compile and flash the project in Windows 11, everything works fine, but if I compile the exact same project in Ubuntu 22.04.3, the SPI doesn't work and I will get "spi_nrfx_spi: Timeout waiting for transfer complete" error.

I'm using the same SDK (v2.1.1) and toolchain (v2.1.1) in both OS

I've attached the pristine build log in both OS

The problem was very simple. The pin configuration for the SPI was default in Ubuntu and I had to re-assigned them. It was not an OS issue. Sorry my bad
