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.

4

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

5

I use the pl2303hx ta ch304g usb

6

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.
