Hi,
I am using nRF5340 DK + NCS v2.0.0 with nrfx backend for SPIM.
For my application I want to trigger a SPIM1 transaction at a fixed interval. To do this, I set up an interrupt on TIMER1 that calls spi_transceive. However, spi_transceive is returning error -116 (ETIMEDOUT) when called from the ISR.
I've attached an example project that I think demonstrates the issue, could you please let me know if this is a bug or if I'm doing something wrong?

The debug logs show the following
