But that’s not an issue in case of S32K118 because it does not support HSRUN.<BR />So, the only thing I can see is to check if some operation is already running:</P> <P><span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="lukaszadrapa_0-1645782127423.png" style="width: 400px;"><img src="https://community.nxp.com/t5/image/serverpage/image-id/171782iED54D7AB1D4E5889/image-size/medium?v=v2&amp;px=400" role="button" title="lukaszadrapa_0-1645782127423.png" alt="lukaszadrapa_0-1645782127423.png" /></span></P> <P>If you use SDK/RTD, it’s checked by drivers.

Current workaround is to check this by yourself. <BR />Regards,<BR />Lukas</P> Fri, 25 Feb 2022 09:43:53 GMT lukaszadrapa 2022-02-25T09:43:53Z https://community.nxp.com/t5/S32K/Programming-conditions/m-p/1419091#M14141 <P>We are developping a Bootloader for the NXP S32K118. Is there any condition we need to check before reprogramming the Flash memory? For example:</P><UL><LI>Is there any voltage range of the microcontroller (VDD) where it is not secure/recommended to reprogramm flash?</LI><LI>Is there any temperature range at the microcontroller where it is not secure/recommended to reprogramm flash?</LI></UL> Thu, 24 Feb 2022 12:39:48 GMT https://community.nxp.com/t5/S32K/Programming-conditions/m-p/1419091#M14141 MMT_BW 2022-02-24T12:39:48Z https://community.nxp.com/t5/S32K/Programming-conditions/m-p/1419708#M14166 <P>Hi Melissa,<BR />Flash operations are supported across whole functional temperature and voltage range. <BR />In case of S32K14x, CSEc and EEPROM writes/erase cannot be executed in high speed run mode (HSRUN).
