I am working on an embedded system with an MX35 CPU.
The baud rate 921600 is correct. We use USB.
I usually recover from a broken system by flashing a new rootfs to the device.
We use U-Boot as bootloader and Linux 3.2.x kernels (with many adaption for our hardware).

Do I need to activate "CONFIG_LOGIN_SESSION_AS_CHILD" in busybox?
