Which image have you tried?

The problem has been solved by turning off the power and then disconnecting all connections (including the serial network cable) when booting with SD. Wait a few minutes and then power on again.

Which serial adapter do have used? Make sure it has 3v3 ttl level

I use the pl2303hx ta ch304g usb

At least these break wifi due to additional pullup

Not heared about boot issues yet and do not see it by myself…tried also ch340g

Thanks, I had this problem with the openwrt website, but the banana pie website provided no problem.
