I'm assuming you have a PineTab2. Follow these instructions; insert a bootable SD card and use the "SD BOOT MASKROM" switch on the adapter to force it to boot from the SD card. That should work regardless of what you have on the SPI/eMMC.
IMPORTANT: Make sure that the SD card image you are using has it's own U-Boot image. If you try to use e.g. a Mobian SD card, it won't work for you because it expects you to have an existing U-Boot installation on the SPI/eMMC (which you had previously accidentally wiped).
In case you have a PineTab1 it's actually even easier; it will automatically boot from the SD card if it has a valid OS+U-Boot image on it.
