LPC54016 Flash to RAM

Hello NXP community.

I am running a project using LPC54016JBD100E MCU and I have a problem loading the IMG from external flash(W25Q128JVFM) to RAM.

The problem is that that using the IMG from the flash slowing my project , functions that works perfectly by running from RAM does not work running from my FLASH , so this is the reason I want to copy the IMG from FLASH to RAM.

ISP pins configure as HIGH,HIGH,HIGH
IMG is loading from flash without problem.
W25Q128JVFM defined on startup.

Looking at the datasheet and user manual I saw a img_type bit that can be configure,

to copy the IMG from FLASH to RAM ,by changing XIP bit to 0 (load img),

but when I changed the__imghdr_imagetype = 3; to __imghdr_imagetype = 1, the system did not succeed to upload from the ext FLASH.

Also I tried to change the IMG_BAUDRATE from 0 to 96000000 , but the clock remain 24Mhz.

But the best will be to find a solution to copy from flash to ram,

I will be glad for any guidance, thank you.

Best regards Dan Iton.

Hello @DanIton92

You can refer to LPC54018M SDK demo running in RAM, for example hello_world,

it is copy from external flash to RAM.

The demos without xip normal run in RAM.
