I would recommend testing with one of the SPI examples from the SDK. These do need JP20 and JP21 in place.</P> <P>Regards,<BR />Gustavo</P> Thu, 09 Sep 2021 21:03:23 GMT gusarambula 2021-09-09T21:03:23Z https://community.nxp.com/t5/LPC-Microcontrollers/LPC55S16-SPI-SDK-code-not-working/m-p/1330413#M46303 <P>Hi, Im working on to LPC55S16-evk board. i have LPC55S16 board set as master and STM32F429ZI development board as slave. im using SDK Code with no changes. still i receive only junk on stm32f429zi board. i checked in loopback, the communication works fine.&nbsp; I had faced the similar issue wrt UART but later i found the jumper JP12 has to be installed. is there anything im missing in SPI like jumper installation or any other issue? Please help</P> Thu, 26 Aug 2021 13:44:37 GMT https://community.nxp.com/t5/LPC-Microcontrollers/LPC55S16-SPI-SDK-code-not-working/m-p/1330413#M46303 amulya0129 2021-08-26T13:44:37Z https://community.nxp.com/t5/LPC-Microcontrollers/LPC55S16-SPI-SDK-code-not-working/m-p/1337918#M46441 <P>Hello amulya0129,</P> <P>My apologies for the delay.
