^C or most keys should enter the uboot cli.  eg, this is a rockpro64
but it should be the same:

---
....
scanning bus usb@fe900000 for devices... 1 USB Device(s) found
       scanning usb for storage devices... 0 Storage Device(s) found
Hit any key to stop autoboot:  0 
---

at this point any key should enter the u-boot prompt.  at this point
you should be able to choose directly which media to boot from.  i
*think* that "run bootcmd_mmc1" will choose the sd card.  you can
use "printenv" to look at all settings/commands to use, including
eg, "mmc dev 1" and "mmc info" to look at the sd card info.


what u-boot is installed?  i assume it is 2022.01 from either pkgsrc
or the armbsd image?  those should default to using the sd card, even
if u-boot starts from emmc.  (see
pkgsrc/sysutils/u-boot/patches-2022.01/patch-include_configs_rockchip-common.h
for details about the order-switch in this version.)

do you have a uart?  there will be slightly more info via uart than
on the panel, but with 2022.01 the panel should be fine for most
failure mode fixes.
