Orange Pi4 U-boot: sdram_init: LPDDR3 - 933MHz failed!


Recommended Posts

Hello!
I wrote the wrong bootloader to the emms, now the download does not happen with either emmc or micro-sd.

U-Boot TPL 2020.10-00676-g9885313b9a (Oct 13 2020 - 06:24:16)
sdram_init: LPDDR3 - 933MHz failed!
rk3399_dmc_init DRAM init failed -22
Missing DTB

Now I can't use the board in any way, how can I clear the emmc memory?

did you try this?

Maybe it helps...

No, I set the bitrate to the correct one.
It helped me to close contact TP50265 to GND during power-on.
