Since i don't want that stdout is redirected to LCD (customer isn't interested in watching all output of u-boot) i need something to write out of scripts to the screen. For example we write of script in which mode we are booting, maybe also some default ip settings in recovery mode. > > > Signed-off-by: Hannes Petermaier <oe5hpm@oevsv.at> > > --- > > common/lcd.c | 17 +++++++++++++++++ > > 1 file changed, 17 insertions(+) > > > > diff --git a/common/lcd.c b/common/lcd.c > > index f418da9..755388f 100644 > > --- a/common/lcd.c > > +++ b/common/lcd.c > > @@ -279,6 +279,17 @@ static int do_lcd_clear(cmd_tbl_t *cmdtp, int flag, int argc, > > return 0; > > } > > > > +static int do_lcd_puts(cmd_tbl_t *cmdtp, int flag, int argc, > > + char *const argv[]) > > +{ > > + if (argc != 2) > > + return CMD_RET_USAGE; > > + > > + lcd_puts(argv[1]); > > + > > + return 0; > > +} > > + > > static int do_lcd_setcursor(cmd_tbl_t *cmdtp, int flag, int argc, > > char *const argv[]) > > { > > @@ -306,6 +317,12 @@ U_BOOT_CMD( > > " <col> <row> in character" > > ); > > > > +U_BOOT_CMD( > > + puts, 2, 1, do_lcd_puts, > > "puts" is too generic for an lcd specific function.

Only thing for decission was, that existing commands are allready defined within lcd.c. But i've no problem to move it.

Alright, then please explain in the commit message that this function is meant to give user the option to output to lcd without enabling lcd console. > >> >>> Signed-off-by: Hannes Petermaier <oe5hpm@oevsv.at> >>> --- >>> common/lcd.c | 17 +++++++++++++++++ >>> 1 file changed, 17 insertions(+) >>> >>> diff --git a/common/lcd.c b/common/lcd.c >>> index f418da9..755388f 100644 >>> --- a/common/lcd.c >>> +++ b/common/lcd.c >>> @@ -279,6 +279,17 @@ static int do_lcd_clear(cmd_tbl_t *cmdtp, int > flag, int argc, >>> return 0; >>> } >>> >>> +static int do_lcd_puts(cmd_tbl_t *cmdtp, int flag, int argc, >>> + char *const argv[]) >>> +{ >>> + if (argc != 2) >>> + return CMD_RET_USAGE; >>> + >>> + lcd_puts(argv[1]); >>> + >>> + return 0; >>> +} >>> + >>> static int do_lcd_setcursor(cmd_tbl_t *cmdtp, int flag, int argc, >>> char *const argv[]) >>> { >>> @@ -306,6 +317,12 @@ U_BOOT_CMD( >>> " <col> <row> in character" >>> ); >>> >>> +U_BOOT_CMD( >>> + puts, 2, 1, do_lcd_puts, >> >> "puts" is too generic for an lcd specific function.

That sounds better, yes. > > Only thing for decission was, that existing commands are allready defined > within > lcd.c. That's ok; we should place code where it's most relevant, and your command is related to lcd console functionality. > But i've no problem to move it. What do you say? let's move? Yes, please move it to lcd_console.c
