hi,everyone.

i meet a question,when i debug uboot (am335x_evm),i do this;

1)load program,and PC shows 0x80800000

2)load symbol in 0x9FF43000 (by gd->relocaddr)

3)make a breakpoint in " board_init_r()" function .Now this is my problem ,it not stop at the breakpoint.

this function is in arch/arm/lib/board.c

make sure it must run this function,because i change the print logs,and then it print it through the debug uart.

I refer the below web,and it says

"In this lab we will be setting a breakpoint AFTER the code has been relocated, so you will have to reload the symbols as instructed below."

but the relocate_code function is no return ,i can't set the breakpoint.

Hello,

Sorry for the delayed response. I am not familiar with the guide that you are following. I am going to move your post to the Sitara forums. The experts there should be familiar with that training guide you are following and may have some suggestions to help you.

Thanks
