samples/hello no output on BBB

[Nils Hölscher]

Hi,

I make bootable SD-image for the BBB with Chris tool:
$ rtems-boot-image -o sd-card.img -b u-boot-beaglebone -s 32m -k hello.exe
u-boot/MLO u-boot/u-boot.img

When I boot with serial connected I get the following output:
"
Booting kernel from Legacy Image at 82000000 ...
Image Name:   RTEMS
Created:      2019-06-17   8:03:14 UTC
Image Type:   ARM Linux Kernel Image (gzip compressed)
Data Size:    48801 Bytes = 47.7 KiB
Load Address: 80000000
Entry Point:  80000000
Verifying Checksum ... OK
Uncompressing Kernel Image ... OK

Starting kernel ...
"

But the Hello world prints are missing.
The board just restarts after a few minutes.
Can anyone help me, please?

I attached my config log from samples.

Best,
Nils
