Are you using this setup for the BMU? Or do you have another board? I would suggest double-checking the schematics with the pins of the SPI Config blocks.</P> <P>Regards,</P> <P>Marius</P> Fri, 18 Nov 2022 09:28:07 GMT https://community.nxp.com/t5/Model-Based-Design-Toolbox-MBDT/Status-3-Communication-timeout/m-p/1556397#M7858 mariuslucianand 2022-11-18T09:28:07Z
