Firstly my apologies for not subscribing - I thought I had, but probably
pressed a wrong button somewhere.
Thanks for your quick response
Yes, it is only initramfs which needs to be changed to bring it to life.
Full dump from serial port is attached as text file, but last few lines

Does this help point up what I've done wrong?
With many thanks,
