Hello,

The Rockpro64_V2.1 2018-07-02 using master code base freezes
with only the following output:

U-Boot TPL 2019.10-rc2-00001-gdf33f86468-dirty (Aug 16 2019 - 22:31:31)

Whereas another board dated 2018-06-06 works and outputs the following:

U-Boot TPL 2019.10-rc2-00001-gdf33f86468-dirty (Aug 16 2019 - 22:31:31)
Trying to boot from BOOTROM
Returning to boot ROM... 

U-Boot SPL 2019.10-rc2-00001-gdf33f86468-dirty (Aug 16 2019 - 22:31:31 +0200)

Both board have 4G RAM.

U-Boot was built by Mark Kettenis from master with only the
baud rate changed for both tests. The 2018-07-02 board has different
markings for the CPU and the RAM as follows:

     2018-06-06       2018-07-02
CPU: RK3399           RK3399
     SBETMF976 1652   SBETNM271 1826

RAM: PS006-075 BT     PS052-053 BT
     N1YJ             83RL

Please let me know if there is additional information needed to
further diagnose the boot freeze.

Regards,
-Kurt
