I was so far assuming it's a user > error, so haven't tried bisecting yet. I am using "U-Boot 2017.03". However, I realise that I am currently based upon L4T rel24.2.1 (as rel28.1 was not available when I started using L4T for testing upstream). I hope it would not matter, but you never know. I plan to move to rel28.2 once it is released. If we think it is a problem with rel28.1 I should be able to test my side. Cheers Jon -- nvpublic
