hi, 
current I use IMX6ULL EVK to do development without any OS(like linux, RTOS and so on). 
I use IAR build out hello world project with ram.icf. And then I use JTAG to download hello world.bin to QSPI flash. But it can not work when I config EVK to boot from QSPI. 

 

my user story: 
1. use IMX6ULL EVK to do development without linux; 
2. build official SDK project with IAR; 
3. download code to QSPI flash; 
4. boot from QSPI flash and run code in DDR; 

 

How can I do? 

 

By the way, I want to use MFG tool to download code to QSPI flash refer to <Getting Started with MCUXpresso 
SDK for i.MX 6ULL Derivatives>. But it failed to download. It always reset cause by POR.

 

another question, Is the Boot ROM code can be programed?
