I want to reset EEPROM to factory default because board can’t boot from TF card (mmc) no matter what and how I try. It boots fine from emmc.
current TLV is here (from u-boot prompt)
=> tlv
TLV: 0

Checksum is valid
My last idea to boot from TF card is to reset to factory setting and try again

Hello, could you provide the complete SD card boot log? I’ll ask around for you.

here is short guide I wrote year ago how to install Alpine linux on BPI-F3:
https://arvanta.net/alpine/alpine-on-spacemit/
there is script I created to make TF card image and link to image which can be downloaded and flash (dd) to mmc.
this all worked fine for some people which use Alpine on bpi-f3 and worked for me but about month ago stopped to boot from mmc while works fine from mmc.
I’ve added opensbi and u-boot to alpine for bpi-f3
