u-boot with print issue on AM437x

WTMEC_Will Hsu

Hi TI Team,
I have added some print message in mux.c of u-boot.
but I cann't see any message on debug console.
Is there something wrong ???

SW: SDK 01.00.01.07
HW: TMDXEVM437X

Exmple:
u-boot/board/ti/am43xx/mux.c
void enable_board_pin_mux(void)
{

debug("Will --> mux.c\n");
printf("Will ----> mux.c\n");

puts("Will ------> mux.c\n");

configure_module_pin_mux(mmc0_pin_mux);

configure_module_pin_mux(i2c0_pin_mux);

configure_module_pin_mux(mdio_pin_mux);

Hi,

You should check if you are actually trying to print before the debug UART is initialized.

Hi,

If you want to use debug(), you should add
#define DEBUG at the beginning of mux.c

Also try placing your prints inside the conditional statements in mux.c

Best Regards,
Yordan
