And why must it be done mandatorily, without a chance for the user to configure different behaviour? Please feel fre to define defualt settings, but please always give the user an option to select different behaviour. This is what the environment variables are made for - if we would always sent them mandatorily in the code, we would nbot need any representation in the environment. Best regards, Wolfgang Denk

Right - but this is not part of the patch, it is only in the commit message and regards code that is already mainlined. The patch sets only CONFIG_BOARD_LATE_INIT. The part you dislike should be fixed by a separate patch. Stefano

This is a real fix - board does not run without it. According to our discussion in the thread, dropping setenv("stdout", "serial") in code should be done in a separate patch.

I thnked about and there is a better solution. I drop your patch from u-boot-imx and I send a new on for review, fixing the same issue. Stefano

Define CONFIG_BOARD_LATE_INIT so that the serial console messages can be redirected to the serial port. This is needed because in mx53loco.c we have: #ifdef CONFIG_BOARD_LATE_INIT int board_late_init(void) { setenv("stdout", "serial"); return 0; } #endif Signed-off-by: Fabio Estevam <fabio.estevam@freescale.com> --- include/configs/mx53loco.h | 1 + 1 files changed, 1 insertions(+), 0 deletions(-)
