I'm testing the SPI-slave functionality based on the routine ncs/v3.3.0/zephyr/tests/drivers/spi/spi_controller_peripheral.
The original code uses the pins of SPIS21, but after I modified it to use the pins of SPIS00, SPIS00 fails to receive SPI data — the waveforms and hardware connections are normal.
Could you help check what the issue is? I've attached my modificatio3731.nrf54lm20dk_nrf54lm20a_cpuapp.overlayns.
