No sdcard access when booting from emmc?

Hi, I think I messed up the OpenWRT setup, before I was pretty sure I had mounted the SD card (the SD card is recognized by Windows, and I tried both ntfs and exfat), but after messing up the setup I think I lost the connection to the SD card. I tried to re-flash the emmc via nand, but it seems that the emmc was not cleared, and the files that existed were still present after re-flash. Is there a chance that I messed up the setup? If so, can I clear the emmc to do a clean install of OpenWRT via nand? Or can I just make the SD card work again?

And if you ask me why I need the SD card so badly: I want to install docker on OpenWRT, and then a few other things like portainer, homeassistant, adguard etc., but 8gb emmc is not enough, I will definitely buy an nvme drive, but not now

To answer the title of your topic:

The emmc and sd cannot be accessed simultaneously. When booting from emmc, your sdcard is not accessible.

oh… So my solution is to temporary set everything on sdcard, or boot from emmc and buy nvme, and there is no other way? Is that correct?

You can use an usb stick.
