Here's what I have tried:
$ sudo ./flash.sh p2371-2180-devkit mmcblk0p1
This should work. Which u-boot binary are you copying and where are you copying it?
I copy the u-boot-dtb.bin over u-boot.bin in the L4T directory Linux_for_Tegra/bootloader/t186ref/p2771-0000/500/u-boot.bin.
I downloaded the .rpm from https://build.opensuse.org/package/show/hardware:boot/u-boot-p2371-2180 extracting all of u-boot, u-boot.bin, u-boot.dtb and u-boot-dtb.bin to bootloader/t210ref/p2371-2180/ - and as described it makes a difference in that it then ceases to boot to a U-Boot prompt.
Sorry, looks like I mixed TX1 and TX2. I see you are using TX1. However, I believe you are still booting the wrong u-boot file.
If you look at the p2371-2180-devkit.conf you will see that it has ...
DFLT_KERNEL_IMAGE="bootloader/${target_board}/p2371-2180/u-boot.bin
For using the upstream u-boot, we need to use the u-boot-dtb.bin and not the u-boot.bin. So you can either ...
- Update the p2371-2180-devkit.conf to use the u-boot-dtb.bin that you
copied. 2. Move the u-boot-dtb.bin from your rpm to bootloader/t210ref/p2371-2180/u-boot.bin.
Both in the Nvidia tarball and in our upstream based package builds, u-boot.bin and u-boot-dtb.bin are identical. Since some time u-boot-dtb.bin gets copied over as u-boot.bin for consistency upstream.
Should this work with the vanilla upstream files, or do they need any headers or signatures or something?
Do any of you have that upstream version booting successfully, or might it be an upstream U-Boot regression? I was so far assuming it's a user error, so haven't tried bisecting yet.
