[U-Boot-Users] Adding devices' init in board.c

[Frederic Kwiatkowski]

Hello all

I'm looking to init an external device (an lcd screen through a RM9200
based board) while starting U-Boot. So i've write a binary file to
check if my .C sources were right and load it into the RAM. Typing the
go 20000000 command (after a tftp transfer) get success and my device
is initialised.

So i've tryed to put a function call in my arm board.c and while i'm
building the new U-Boot.bin, everything is right (the .o file is
created and u-boot.bin is build), but nothing is running (there is no
message and prompt on my RS232 Debug display and the board is not
booting).

Is there something specific to do to init a device using board.c? or
is there any possiblity to include and launch the binary file in
U-Boot?

With regards

Does u-boot return to the command prompt after this init?

Hook up the bdi and start debugging

#define CONFIG_BOARD_EARLY_INIT_F 1         /* Call

#define CONFIG_MISC_INIT_R      1           /* Call misc_init_r(am) from
$board.c        */

Hi, thanks for your indication

Concerning the U-Boot's prompt, we haven't any prompt, that the main
problem concerning the text debugging of my piece of code
