Rt600 uart mboot Blinky HELP

[cjwsam]

Hey All, 

I am currently working on a project and trying to load a LED blinky bin file from my pc via uart to rt685-evk in mboot mode and i cannot seem to execute it 

Any guidance and or example commands to send and execute the code would be amazing 

i have used 

blhost -p com3 write-memory 0x1c000 .\evkmimxrt685_gpio_led_output_gpio_test.bin

but i can seem to execute it 

Thanks in Advance

Hello
Hope you are well.

I suggest you use the MCUBootUtility Tool: https://github.com/JayHeng/NXP-MCUBootUtility

Let me know if this is helpful, if you have more questions do not hesitate to ask me.
Best regards,
Omar

Thanks, I have been using this

The problem is i want to execute the device without having to change the ISP pins as we will need to update the firmware without changing pins on our PCB  

I.E: Other chip with OTA will force new bin into the rt600s external NOR on our PCB, reset it and OTA bootloader will load from new firmware 

So is there any way on the EVK to force the device to boot from the flexSPI NOR without switching the isp pins noting the "execute from RAM" function on the MCUBootUtility doesn't work (no attribute error)
