Look at the following page about SPL booting sequence:

https://freescale.sdlproducts.com/LiveContent/content/en-US/QorIQ%20LS2080A%20SDK%201.0/GUID-E6F5FCF...

The T4240 does not have possibility for accessing to the SPI Flash during SPL booting.

Send your command sequence for accessing to the SPI Flash during SPL booting.


Have a great day,
Pavel
