We set pins according to the Table 74 from&nbsp;i.MX RT1050 Crossover&nbsp;Processors Data Sheet&nbsp;for Consumer Products. We&nbsp; used Flexspi_A before without an adjusment (we only set internal boot). Can Flexspi_B pins&nbsp; also be used this way?&nbsp;</P><P>Kind Regards,</P><P>Kaan.</P> Fri, 25 Sep 2020 14:26:31 GMT omerkaanbasakin 2020-09-25T14:26:31Z https://community.nxp.com/t5/i-MX-RT-Crossover-MCUs/How-TO-Boot-From-FlexSPI-B/m-p/1159401#M10288 <P>Hello we are using IMXRT1052 processor on custom board, MCUXpresso IDE for programing and PE Micro UniversalMultilink for debugging.
