https://community.nxp.com/t5/Processor-Expert-Software/XIP-stops-running-after-boot-on-custom-MIMXRT1015-board/m-p/1490424#M5184 <P>Hi, I have a custom board running just a blink example. The board is based on the MIMXRT1015 EVK. It has the same flash chip, but uses the 4A package instead of 5A. Whenever I flash the chip, I can see the flash being programmed on an oscilloscope. The link I am using says it verifies the flash correctly.&nbsp;</P><P>Whenever the MCU boots, I can see the flash start up but immediately stops. Debugging never gets to main. When I execute the code from RAM it works correctly. Has anyone seen something like this?</P> Fri, 15 Jul 2022 15:12:41 GMT EricBuschCDI 2022-07-15T15:12:41Z https://community.nxp.com/t5/Processor-Expert-Software/XIP-stops-running-after-boot-on-custom-MIMXRT1015-board/m-p/1490424#M5184 <P>Hi, I have a custom board running just a blink example.
