Pretty sure you will still need to jumper/disable the SPI.
On the uboot github page, they recommend the following:
Quote:In this case, you can [color=var(--color-text-link)]temporarily disable SPI by bridging pins 23 (SPI CLK) and 25 (GND) on the Pi-2 Bus header. This will disable SPI and let you boot from eMMC or SD card; you can then interrupt U-Boot by pressing a key on the serial console at the "Hit any key to stop autoboot" prompt, remove the bridge between pins 23 and 25, and then enter:[/color]
Code:sf probe
sf erase 0 400000
to erase the SPI flash, so it won't be used to boot.
From the looks of it, a serial console is required. Was anyone able to get this done without one?
I figured out what my issue was. I have an external USB hub with a power supply of its own. It seems to interfere with the boot (possibly affecting the voltage). I have to insert it in seconds after and it works just fine. I was able to boot with SD card finally and now can restore my spi settings.
