Hi,

 

We are using custom board with i.MX8M quad processor and it hangs after SPL boot with below prints.

 

U-Boot SPL 2017.03-imx_v2017.03_4.9.51_imx8m_ga+g2537522 (Aug 07 2018 - 10:19:03)

Trying to boot from MMC2

It wont go further than above prints.

Can anyone let me know the reasons for hanging here.

 

Thanks in advance.
