https://community.nxp.com/t5/i-MX-RT-Crossover-MCUs/Custom-bootloader-imxrt1170/m-p/1956331#M31841 <P>I am trying to port already existing boot firmware from STM platform to IMXRT platform.&nbsp;</P><P>I have 2 QSPI Flashes. First one is executing the code only and the second is for storing some data.</P><P>I am also trying to add boot firmware to the second one. Every boot time, I will start to run from the second QSPI flash. If no new firmware is upgraded/loaded within a pre-defined time interval, I will start to execute main app program in&nbsp;first QSPI. At that time I am also trying to force second QSPI flash to "read/write" mode thereafter. However I could not find a way how to do that. Can you give me any example or show me a way of doing it?</P> Wed, 18 Sep 2024 07:18:30 GMT burhanhagi 2024-09-18T07:18:30Z https://community.nxp.com/t5/i-MX-RT-Crossover-MCUs/Custom-bootloader-imxrt1170/m-p/1956331#M31841 <P>I am trying to port already existing boot firmware from STM platform to IMXRT platform.&nbsp;</P><P>I have 2 QSPI Flashes.
