I am building my image using IAR and the sample project containing BSP for i.MUX6UL provided by embOS. It is a simple application to check CPU performance. After building this application Start_imxUL.bin is generated. I am trying to boot this image from sd card. I don't know how to check or detect entry point of this image. Kindly help me to figure this out. It will be a great help for me.
