Hello, I have flashed the flash.img file but it does not autoboot into openwrt. I have to first boot into bootloader then after i issue boot manually it boots into openwrt.

reaches above the a reset happens

If I enter the bootloader and issue boot command it successfully boots into openwrt.

in uboot the printenv gives me the following:

Hello, unfortunately I do not have the device anymore to further test. I will have another one in dicember, but I can start looking into the issue. I will try to update you as soon as I understand the root cause.

How did you flash?
