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.
Does u-boot return to the command prompt after this init?
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).
Hook up the bdi and start debugging
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?
#define CONFIG_BOARD_EARLY_INIT_F 1 /* Call board_early_init_f(lash) from $board.c */ #define CONFIG_MISC_INIT_R 1 /* Call misc_init_r(am) from $board.c */
