I have seL4 running on a TK1 using linux-tk1-initrd. I'd like to get the linux-tk1-debian version running to load the userspace off of the emmc drive of the TK1. FWIW, I did flash the TK1 to the latest verison, R21.5.
The default DTS has root=/dev/mmcblk0p2 in the bootargs. When booting with this, I get a kernel panic. I also tried changing that to root=/dev/mmcblk0p1 (since that partition was the larger one on the emmc). It also gives a kernel panic, albeit a different message. With mmcblk0p1, the message I get is: [ 10.092841] EXT2-fs (mmcblk0p1): error: couldn't mount because of unsupported optional features (240) [ 10.102749] EXT4-fs (mmcblk0p1): couldn't mount as ext3 due to feature incompatibilities [ 10.137427] EXT4-fs (mmcblk0p1): mounted filesystem with ordered data mode.

Will an older version of the TK1 image from Nvidia work or do I need to do a custom debian install (like this https://wiki.debian.org/InstallingDebianOn/NVIDIA/Jetson-TK1)? _______________________________________________ Devel mailing list [email protected] https://sel4.systems/lists/listinfo/devel
