I know. My point was about "downstream" - running AArch32 code on arm64 will be generic code, no Nvidia magic, so Matthias can look at upstream source. The Andromeda Box Edge and Odroid-C2 also run a 32-bit userland. ThunderX was the only exception to the rule I could think of, name similarity is purely coincidental. As for the Tegra X1, you may find this interesting: ftp://download.nvidia.com/tegra-public-appnotes/t210-nvtboot-flow.html Regards, Andreas -- SUSE Linux GmbH, Maxfeldstr. 5, 90409 Nürnberg, Germany GF: Felix Imendörffer, Jane Smithard, Graham Norton HRB 21284 (AG Nürnberg) ------------------------------------------------------------------------------ _______________________________________________ OpenOCD-devel mailing list OpenOCD-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/openocd-devel
