Cannot build u-boot for beaglebone black

[guyo13]

After building the toolchain and the example sqlite:

git clone git://git.denx.de/u-boot.git
cd u-boot/
git checkout v2017.01
export CROSS_COMPILE=arm-cortex_a8-linux-gnueabihf-
export ARCH=arm
make CROSS_COMPILE=arm-cortex_a8-linux-gnueabihf- am335x_boneblack_defconfig
make CROSS_COMPILE=arm-cortex_a8-linux-gnueabihf-

And I get the following:
.

.
CC arch/arm/cpu/armv7/cache_v7.o
cc1: warning: target CPU does not support THUMB instructions

Makefile:1217: recipe for target 'arch/arm/cpu/armv7' failed
make: *** [arch/arm/cpu/armv7] Error 2

If I try to use the latest master branch of u-boot it compiles but I have to use
make CROSS_COMPILE=arm-cortex_a8-linux-gnueabihf- am335x_boneblack_vboot_defconfig
And then when trying to boot u-boot I get "Unrecognized filesystem type" on the serial and it continuously tries to boot from PXE...

Assistance would be appreciated.

More specifically, this is what happens when I try to use the MLO and u-boot.img from the latest version (serial output):

U-Boot 2019.07-rc4-00001-g68b90e57bc (Jun 13 2019 - 16:00:26 +0300)

And on my computer:
sudo fdisk -l :

Disk /dev/mmcblk0: 29.7 GiB, 31914983424 bytes, 62333952 sectors
Units: sectors of 1 * 512 = 512 bytes

/dev/mmcblk0p2 133120 2230271 2097152 1G 83 Linux

So there are partition tables and I copied MLO and u-boot.img, I also tried u-boot.bin and it didn't work

did you managed to work it out?
