Hello... I am having problem with the insane 1,500,000 bps baud rate serial2 port in rockchip64 I manage to configure the file in configs/rock64-rk3328_defconfig and change it from 1500000 to 115200.. The ship starts to boot in 115200 than it writes on the serial line: U-Boot SPL 2017.09 (Sep 24 2019 - 14:04:29) board_init_sdmmc_pwr_en setup_ddr_param 1 booted from SD Trying to boot from MMC2 ================================ after that it reverts to 1,500,000 bps and writes: ================================ D:0x805 Y In LPDDR3 333MHz Bus Width=32 Col=11 Bank=8 Row=15/15 CS=2 Die Bus-Width=32 Size=4096MB ddrconfig:7 OUT NOTICE: BL31: v1.3(release):22b599a NOTICE: BL31: Built : 09:06:22, Jul 12 2019 NOTICE: BL31:Rockchip release version: v1.3 INFO: ARM GICv2 driver initialized INFO: Using opteed sec cpu_context!

Thank for any help
