My code is working fine with MCUXpresso IDE and runs flawlessly. However, the moment I power cycle the board, the firmware disappears! The chip becomes completely unresponsive, and I have to re-flash it. I have tried everything, including different LPC5504 boards, various power supplies, and double-checking the boot pins. But nothing seems to work. My Stonegrill restaurant is lacking behind because of this. Is there someone else who faces similar issues? </SPAN></P> Sat, 21 Jun 2025 07:41:46 GMT https://community.nxp.com/t5/LPC-Microcontrollers/Unresponsive-LPC5504/m-p/2120505#M58393 lumine01 2025-06-21T07:41:46Z https://community.nxp.com/t5/LPC-Microcontrollers/Unresponsive-LPC5504/m-p/2122222#M58413 <P>I would really appreciate if someone could help me find a solution since my <A href="https://theflamesgalore.com/" target="_self">Stonegril restaurant</A> is suffering because of this.</P> Tue, 24 Jun 2025 12:15:09 GMT https://community.nxp.com/t5/LPC-Microcontrollers/Unresponsive-LPC5504/m-p/2122222#M58413 lumine01 2025-06-24T12:15:09Z https://community.nxp.com/t5/LPC-Microcontrollers/Unresponsive-LPC5504/m-p/2122231#M58414 <P>Just asking the obvious: are you sure you have programmed the FLASH memory with your application, and that you are *not* running a RAM target?</P> Tue, 24 Jun 2025 12:34:36 GMT https://community.nxp.com/t5/LPC-Microcontrollers/Unresponsive-LPC5504/m-p/2122231#M58414 ErichStyger 2025-06-24T12:34:36Z
