Jetson TK1, FreeBSD, and SSD

Fri, 19 Aug 2016 13:30:39 +0000

Looks like my attempt to cheap out on SSD for TK1 has backfired. I went for the cheapest SSD available in local store (Toshiba Q300) but when I tried to checkout FreeBSD sources to the drive I got bunch of WRITE_FPDMA_QUEUED timeouts and system locked up. The same thing happened when I tried to perform checkout on Linux. The drive itself was OK, it survived “svn co …/head” and dd when connected using USB-to-SATA adapter.

I finally got around to BSDify my Jetson TK1. Here is short summary of what is involved. And to save you some scrolling here are artifacts obtained from whole ordeal: https://people.freebsd.org/~gonzo/arm/jetson-tk1/

U-Boot

First of all - my TK1 didn’t have U-Boot. Type of bootloader depends on the version of Linux4Tegra TK1 comes with. Mine had L4T R19, with some kind of “not u-boot” bootloader. My first attempt was to use tegrarcm tool, it uses libusb, so it’s possible to build it on FreeBSD with some elbow grease, but once I tried to run it - it gave me cryptic errors and USB is not my strong skill so I took low road and installed Ubuntu VM. For what is’s worth I got the same kind of error on Ubuntu.
