Thanks Andrew, I updated the notes there too, can you please check in your build if the expected files are being used when generating the boot0 blob and the signed binaries?

In my local build in tmp/work/aarch64-poky-linux/tegra186-flash-dry/32.4.4-r0/temp/log.configure I see:

[ 5.4538 ] tegrabct_v2 --chip 0x18 0 --mb1bct mb1_bct.cfg --sdram jetson-tx2-4-gb.cfg --misc tegra186-mb1-bct-misc-si-l4t.cfg --scr minimal_scr.cfg --pinmux tegra186-mb1-bct-pinmux-quill-p3489-1000-a00.cfg --pmc tegra186-mb1-bct-pad-quill-p3489-1000-a00.cfg --pmic tegra186-mb1-bct-pmic-lightning-p3489-1000-a00.cfg --brcommand tegra186-mb1-bct-bootrom-quill-p3489-1000-a00.cfg --prod tegra186-mb1-bct-prod-storm-p3489-1000-a00.cfg

so at a first glance the config files seem fine, but please compare their names and contents to your old build see if you spot any difference.

I went through log files and it all looks correct. The bindiff file is the correct one and it’s being using properly in the script. The CFG files all look correct as well. I can’t see the difference.

Hi Andrew, thanks for confirming. I just spotted that the TX2 4GB actually uses a different bpmp dtb so I added another commit to my PR to take this into account. Can you please check if this was causing the issue?

Confirmed working. I flashed the emmc directly and flashed via SD card and both work and connect to the cloud (using tx2 device type for now). Thanks for getting this fixed up.

Could we get this pushed into the 32.5.1 pull request? I suspect many of the changes you made will apply to the TX2 NX, which is available in meta-tegra as of 32.5.0. I have some TX2 NX’s I’d like to get supported as soon as possible. If you can add to PR #179 I’ll start my development work there and hopefully it should make life easier for you to pull in the changes.

Thanks.

Thanks for confirming, I’ve merged the PR. So are you actually interested in using the TX2 4GB with L4T 32.5.1 and not with the current 32.4.4? If so, I can first look at porting them to 32.5.1.

45

Thanks.

32.4.4 meets my current needs but I have greater demand for the TX2 NX, which requires 32.5.1. It would seem that getting TX2 4GB working on 32.5.1 first is a step in the right direction. However, whatever gets TX2 NX support the quickest is what I’m ultimately interested in.

Let me know how I can support. Thanks

I see, in this case there’s no need to release the 4GB image in the dashboard on 32.4.4, we’ll release it directly on 32.5.1. Yes, I’ve ported the changes to PR179 and am planing to start looking into the TX2 NX support in the next days. You can can keep an eye on that pull request as all TX2 NX related changes will be included there.

47

Awesome, thanks a lot.

I’ll give the TX2 4GB and TX2 NX machines a go soon and report back.
