ls1046a u-boot is not executed

[james13]

Hello,

I used the ls1046a to build a customized board. However, the board does not boot. 
As shown in the log below, it stops at SPSR = 0x3c9.

Is there a solution?

Probably the system stuck at the end of ATF or the debugging of u-boot, please debug atf and u-boot to find out where it stuck.

Do you have CodeWarrior for ARMv8 and CodeWarrior TAP?

If yes, please refer to document https://community.nxp.com/t5/CodeWarrior-for-QorIQ-Knowledge/Use-CodeWarrior-for-ARMv8-to-Debug-U-bo... to debug u-boot.

The procedure to debug ATF is similar as debugging u-boot.
