Hi,

I am trying to install u-boot on my Walnut with PPC405. After I load the program, the u-boot hangs without any output on the serial console. I located that the program is stopped at the point of where board_init_f() is called. More specifically, the u-boot stop at for (init_fnc_ptr = init_sequence; *init_fnc_ptr; ++init_fnc_ptr) { if ((*init_fnc_ptr) () != 0) { hang (); } }

None of the function init_fnc_ptr pointing to has been called successfully. For test purpose, I wrote the following codes and put them in board_init_f(): 409 char s[10] = {'h','e','l','l','o'}; 410 if (s[0] == 'h') { 411 s_putc('y'); 412 } else { 413 s_putc('n'); 414 }

s_putc() is a function I created to send one char to UART. It has been tested working fine. But the u-boot hangs at line 410. Then I changed the test code to the following: 409 // char s[10] = {'h','e','l','l','o'}; 410 char s[10]; 411 s[0] = 'h'; 412 s[1] = 'e'; 413 s[2] = 'l'; 414 s[3] = 'l'; 415 s[4] = 'o'; 416 if (s[0] == 'h') { 417 s_putc('y'); 418 } else { 419 s_putc('n'); 420 }

Then the UART showed a 'y' on the screen, which is what I expected. So from the tests I did above, seems some thing wrong with the pointer. It also explains the reason why init_fnc_ptr didn't work well. But I couldn't figure out what is wrong. I would appreciate if any one can give me some clues.

Thanks! Frank
