SPI long handler and crachhttps://devzone.nordicsemi.com/f/nordic-q-a/14201/spi-long-handler-and-crachHello, Platform nRF52 with SDK 11 (S132) I use nrf_drv_spi_init to register a Handler (used for screen and SD card so it can be long) I have sometimes crashes when i have activity on SPI and BLE at the same time. My Handler is maybe too long foren-USTelligent Community 13Fri, 22 Jul 2016 16:56:28 GMTRE: SPI long handler and crachhttps://devzone.nordicsemi.com/thread/54263?ContentTypeID=1Fri, 22 Jul 2016 16:56:28 GMT137ad170-7792-4731-bb38-c0d22fbe4515:afd55f61-80bd-49ee-b4c9-285970718c65bvuong87<p>Hi, I had a quick question on this:</p> <p>From where does the conflict arise if the SPI IRQ priority is APP_IRQ_PRIORITY_HIGH? My understanding of the IRQ priorities is all BLE and SD related priorities run at level APP_IRQ_PRIORITY_HIGHEST, so even if SPI is running at APP_IRQ_PRIORITY_HIGH, shouldn&#39;t the SD still be able to take control of the system as needed?</p> <p>Thanks!</p><div style="clear:both;"></div>RE: SPI long handler and crachhttps://devzone.nordicsemi.com/thread/54262?ContentTypeID=1Tue, 31 May 2016 19:33:58 GMT137ad170-7792-4731-bb38-c0d22fbe4515:1793a952-9dab-41c8-ba8c-8e9d60fc98baFabien Comte<p>Perfect, thank you</p><div style="clear:both;"></div>RE: SPI long handler and crachhttps://devzone.nordicsemi.com/thread/54261?ContentTypeID=1Tue, 31 May 2016 16:01:19 GMT137ad170-7792-4731-bb38-c0d22fbe4515:b736c7c7-496b-40e7-ac63-f9ab604b6b50James Yu<p>In the <code>nrf_drv_spi_config_t</code> struct used to initialize the SPI, you can set the <code>irq_priority</code> field to <code>APP_IRQ_PRIORITY_LOW</code></p><div style="clear:both;"></div>
