However when i debug the software i get spi error and when the code enters this function :</P><P>static void FLEXCOMM8_init(void) {<BR />RESET_PeripheralReset(kHSLSPI_RST_SHIFT_RSTn);<BR />/* Initialization function */<BR />SPI_MasterInit(FLEXCOMM8_PERIPHERAL, &amp;FLEXCOMM8_config, FLEXCOMM8_CLOCK_SOURCE);<BR />/* Enable interrupts */<BR />SPI_EnableInterrupts(FLEXCOMM8_PERIPHERAL, (kSPI_RxLvlIrq | kSPI_TxLvlIrq));<BR />/* Enable interrupt FLEXCOMM8_IRQn request in the NVIC. */<BR /><STRONG>EnableIRQ(FLEXCOMM8_FLEXCOMM_IRQN);</STRONG><BR />}&nbsp;</P><P>The&nbsp;<STRONG>EnableIRQ(FLEXCOMM8_FLEXCOMM_IRQN);&nbsp;</STRONG> it gets stuck in an infinite loop , please suggest and thanks.</P> Fri, 26 Aug 2022 11:14:22 GMT https://community.nxp.com/t5/LPC-Microcontrollers/lpc55s28evk-hspi-EnableIRQ-FLEXCOMM8-FLEXCOMM-IRQN-infinite-loop/m-p/1512323#M49967 vi77 2022-08-26T11:14:22Z https://community.nxp.com/t5/LPC-Microcontrollers/lpc55s28evk-hspi-EnableIRQ-FLEXCOMM8-FLEXCOMM-IRQN-infinite-loop/m-p/1513703#M49994 <P>Hello,</P> <P>How about test the HSPI demo under SDK, and compare your code with demo code ?</P> <P>&nbsp;</P> <P>BR</P> <P>Alice</P> Tue, 30 Aug 2022 07:43:10 GMT https://community.nxp.com/t5/LPC-Microcontrollers/lpc55s28evk-hspi-EnableIRQ-FLEXCOMM8-FLEXCOMM-IRQN-infinite-loop/m-p/1513703#M49994 Alice_Yang 2022-08-30T07:43:10Z
