Hello

I'm trying to run u-boot (sandbox) with a spi emulation, but the start
fails with an error (err=-19).

What I did

# clone and compile u-boot
cd ~/
git clone git://git.denx.de/u-boot.git
cd u-boot
git checkout v2017.11
make sandbox_defconfig menuconfig
 "Sandbox architecture" -> "Run sandbox on 32/64-bit host" (32-bit host)
make

# create file for SPI flash
cd ~/u-boot
dd if=/dev/zero of=spi.bin bs=1M count=4

# run
./u-boot --spi_sf 0:0:M25P16:spi.bin
