Andreas, can you try the TOS packaging script available in our public repo? http://nv-tegra.nvidia.com/gitweb/?p=3rdparty/ote_partner/tlk.git;a=blob;f=tools/gen_tos_part_img.py;h=47828f7028e56a6cffb9b773502b13dc431a015e;hb=HEAD Please let me know if this does not work for you. For the upstream ATF code, our downstream has not caught up with upstream yet, so I am not sure if upstream would directly work for TX1. But its definitely worth a try. -----Original Message----- From: Tom Warren Sent: Thursday, February 15, 2018 7:44 AM To: Jonathan Hunter <jonathanh@xxxxxxxxxx>; Andreas Färber <afaerber@xxxxxxx> Cc: linux-tegra@xxxxxxxxxxxxxxx; U-Boot <u-boot@xxxxxxxxxxxxx>; Alexander Graf <agraf@xxxxxxx>; Mian Yousaf Kaukab <yousaf.kaukab@xxxxxxxx>; Varun Wadekar <vwadekar@xxxxxxxxxx> Subject: RE: How to test new bootloaders on Jetson TX1? -----Original Message----- From: Jonathan Hunter Sent: Thursday, February 15, 2018 8:39 AM To: Andreas Färber <afaerber@xxxxxxx> Cc: linux-tegra@xxxxxxxxxxxxxxx; U-Boot <u-boot@xxxxxxxxxxxxx>; Alexander Graf <agraf@xxxxxxx>; Mian Yousaf Kaukab <yousaf.kaukab@xxxxxxxx>; Tom Warren <TWarren@xxxxxxxxxx>; Varun Wadekar <vwadekar@xxxxxxxxxx> Subject: Re: How to test new bootloaders on Jetson TX1?

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. [Tom] Current (R28.x) U-Boot requires CBoot to load - we no longer use NVTBoot as we did in R24.x. Hence, upstream U-Boot needs some modifications to be able to be loaded by CBoot instead of NVTBoot. I haven't done that work yet (patches to convert upstream Denx U-Boot source for T210/T186 to use CBoot as the loader - don't know how I'll structure it so old (NVTBoot) bootflow will still work as well as the new (CBoot) bootflow). I've got it on my plate, but other priorities have prevented me from working on it. I'll try to get it into the queue. Until then, you won't be able to load/run upstream U-Boot using the boot flow in R28.x. Sorry.
