Try to program a custom board using BL5340PA module to see LOG

[D.MASSIALA]

I have made a PCB using a BL5340PA module, to start i have tried a simple code to see log from RTT using the SWD SWCLK pin, i am using an NRF5340 DK as debugger/programmer, my pin connection bewteen my board  and nrf5340 dk seem good as i was able to flash the code without error.

But still can't see the log in JLink RTT Viewer.

#include <zephyr/kernel.h>
#include <zephyr/logging/log.h>


LOG_MODULE_REGISTER(main, LOG_LEVEL_DBG);


int main(void)
{
        LOG_INF("Hello from RTT!");
        while (1) {
                LOG_DBG("Toggling");
                 k_msleep(1000);
         }
        return 0;
}
