The Problem is, that the RDVCU5775EVM doesn't receive any messages, because RD33771 doesn't send any. I know that the RD33771C enters sleep mode after 60s, if there's no activity on the Bus, but I'm sending a message from the RDVCU. I don't know what wakeup message and what commands I have to send to get the cell voltages, because I can't find any commands for this board or μC. Maybe I have overlooked something.</P><P>I'm using Matlab R2018b with MBDT MPC57xx. These are my setting for the SPI:</P><P><span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="DaSc_3-1655106566510.png" style="width: 315px;"><img src="https://community.nxp.com/t5/image/serverpage/image-id/183088iD84B36467E5B739A/image-dimensions/315x192?v=v2" width="315" height="192" role="button" title="DaSc_3-1655106566510.png" alt="DaSc_3-1655106566510.png" /></span></P><P><span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="DaSc_4-1655106579288.png" style="width: 309px;"><img src="https://community.nxp.com/t5/image/serverpage/image-id/183089i2C7299674BD66832/image-dimensions/309x307?v=v2" width="309" height="307" role="button" title="DaSc_4-1655106579288.png" alt="DaSc_4-1655106579288.png" /></span><span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="DaSc_5-1655106595926.png" style="width: 400px;"><img src="https://community.nxp.com/t5/image/serverpage/image-id/183091i50783912427A8B89/image-size/medium?v=v2&amp;px=400" role="button" title="DaSc_5-1655106595926.png" alt="DaSc_5-1655106595926.png" /></span></P><P><span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="DaSc_6-1655107220619.png" style="width: 322px;"><img src="https://community.nxp.com/t5/image/serverpage/image-id/183092iA3C2B5042B3A2C96/image-dimensions/322x157?v=v2" width="322" height="157" role="button" title="DaSc_6-1655107220619.png" alt="DaSc_6-1655107220619.png" /></span></P><P><span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="DaSc_7-1655107247884.png" style="width: 322px;"><img src="https://community.nxp.com/t5/image/serverpage/image-id/183093i5AF12ED1A229E219/image-dimensions/322x322?v=v2" width="322" height="322" role="button" title="DaSc_7-1655107247884.png" alt="DaSc_7-1655107247884.png" /></span></P><P><span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="DaSc_8-1655107260186.png" style="width: 320px;"><img src="https://community.nxp.com/t5/image/serverpage/image-id/183094i769BDD98166DFBF8/image-dimensions/320x171?v=v2" width="320" height="171" role="button" title="DaSc_8-1655107260186.png" alt="DaSc_8-1655107260186.png" /></span></P><P>&nbsp;</P><P>Is there anything wrong with the settings or do I have to send the right message?
