Tim,
something in your board config or code must be different, then.
Do you use HDMI or LVDS display?
> Do you perhaps have another board to check this behavior with on master?
I've tested with current master and a modified wandboard configuration:
U-Boot SPL 2021.10-00525-g7a508a7245-dirty (Oct 07 2021 - 23:32:09 +0200)
Trying to boot from MMC1
U-Boot 2021.10-00525-g7a508a7245-dirty (Oct 07 2021 - 23:32:09 +0200)
CPU: Freescale i.MX6SOLO rev1.1 at 792 MHz
Reset cause: WDOG
DRAM: 512 MiB
MMC: FSL_SDHC: 4, FSL_SDHC: 1, FSL_SDHC: 0
Loading Environment from MMC... OK
auto-detected panel HDMI
Display: HDMI (1024x768)
In: serial
Out: vidconsole
Err: vidconsole
Board: Wandboard rev B1
Net: eth0: ethernet@2188000
Hit any key to stop autoboot: 0
=> print stdout
stdout=serial,vidconsole
HDMI monitor displays logo and video console text output starting with:
Board: Wandboard rev B1
Net: eth0: ethernet@2188000
Hit any key to stop autoboot: 0
It works on wandboard.
The wandboard_defconfig in master has CONFIG_CONSOLE_MUX disabled
and CONFIG_SYS_CONSOLE_OVERWRITE_ROUTINE enabled. Therefore I enabled
CONFIG_CONSOLE_MUX and disabled CONFIG_SYS_CONSOLE_OVERWRITE_ROUTINE
via menuconfig for this test.
And additionally I used below patch to enable building this configuration:
diff --git a/board/wandboard/wandboard.c b/board/wandboard/wandboard.c
