Hi there,
There is one issue, I experience with (U-Boot 2020.07) on MT7628DAN, "reset" command issued in hush prompt causes board to hang, until I do a power cycle. On the other hand there is no such issue on mt7688 board.
Do you see no further output? Or is it perhaps stuck at the DDR init code in SPL? Can you please post the log (complete boot log with reset command)?
There is only "resetting..." printed, once the reset command is executed. By the way, I am not using SPL loader. Console output below:

What's interesting, is that "reboot" issued in Linux shell makes board reboot as expected on mt7628 board.
It seems like some sort of configuration issue, but I couldn't find anything specific in the datasheet. Maybe you have some idea what could cause it?
One more thing, when running the following version of bootloader (https://github.com/gnubee-git/GnuBee-MT76x8-uboot) "reset" command works as expected.
I do not have a MT7628 based board, so I can't test. Perhaps Weijie has an idea?
Thanks, Stefan
Thanks, Andrew
