Hello everyone!
I am working with my Tiny4412 board, and the u-boot version is U-Boot 2016.11. After burning the u-boot to sd card, and boot my board from it. There are some error ouput to the console. It seems like that my sd card doesn't initialize completely.
I have enabled the MMC Debug configuration(CONFIG_MMC_TRACE). And the console output is as follow:
