https://community.nxp.com/t5/MCUXpresso-General/Enable-external-RAM/m-p/1302447#M4199 <P>In my project I use the RT1064 MCU with 1MB of on-board RAM. I have a 'simple' project with FreeRTOS/lwip enabled, I use the MQTT module of lwip. This all runs just fine. However, if I upscale my simple project with more functionalities, I notice the DTC_RAM gets over 100% full, so this will not run. However, we have 8MB of external RAM, so I'd like to use it. Unfortunately, I cannot get this to work, on startup, the code straightly runs to a hardfault. What am I doing wrong?</P><P>Please note the attachments for my configuration.</P> Mon, 05 Jul 2021 12:09:18 GMT Daan 2021-07-05T12:09:18Z https://community.nxp.com/t5/MCUXpresso-General/Enable-external-RAM/m-p/1302447#M4199 <P>In my project I use the RT1064 MCU with 1MB of on-board RAM.
