Hello,

i use the go command from the hush shell to execute a function from environment. That function has been initially compiled in U-Boot and was first called in board_late_init().

I call the function by using go #address

on my Arm Cortex A-7 machine the do_go_exec becomes: e1a03000 mov r3, r0 e1a00001 mov r0, r1 e1a01002 mov r1, r2 e12fff13 bx r3

so instruction set is exchanged. This seems to work the function returns and returns back to the hush-shell. My question is now: Is it safe to use the go command to execute U-boot functions or do I miss something here? Does the exchange of the instruction set have some influence on the further execution of U-boot.?

Mit freundlichen Grüßen / Best regards
