ls1026a linux

Hello,

we have a prototype using a LS1026A. We go tout boot loader booting and no are trying to boot Linux. The kernel we are using is running on the LS1046ardb eval board.

Linux dies upon returning from the init_el1 function.

Any clue why this would happen?

Cheers,

Renaud

Is that related to the use of the PPA firmware?

Returning from the function is when the "eret" instructions is run.

Hello, for newer versions of LSDK the TFA firmware (LSDK 18.12 onward) replaces PPA firmware (LSDK 18.09) as trusted firmware in U-Boot boot flow, please check what version you are using.

. I used the PPA firmware from 2018 and Linux boots now.
