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.
