flash the DTB partition with
sudo ./flash -r -k DTB jetson-tx1 mmcblk0p1
It seem that the only way to update DTB file is flash the DTB partition.
“Modifying the Existing extlinux.conf” can not work???
Is there other method to update DTB file in the tx1 OS??? Just like extlinux.conf.
In our product, there is no USB port and RESET button for user. The USB port and Force button and Reset button is just for developers, and will be in a box. The user access the TX1 OS through ethernet lan. So, if we want update the DTB file in R28.1, there are many things to do.
Could you add a method to update DTB file in TX1 OS in next reversion of L4T? Just like extlinux.conf.
I think that there will be many other developers need this function.
I would be interested in the answer as well (I’d like to know if U-Boot deals with device naming in a way which interacts with u-dev). For some general information, there are udev rules which rename “eth…” naming format to “enx…” naming format. From what I understand several years ago administrators of large server farms needed an alternate way to identify where the NIC was in the system, e.g., integrated versus add-on, and so the alternate naming was put in (I prefer the original naming myself).
Apologies for digging up an slightly older thread. Right now I have a TX1 configured to boot off the SD card. I’m under the impression that it’s a 2 stage boot though, where it will start booting from the eMMC and then switch to the SD card to load the kernel. That being the case, to flash the dtb should I still be using mmcblk0p13, switch to mmcblk1p13, or use both?
I think you’ll find that external boot media is only for the root partition. There is an option as to whether the boot subdirectory with extlinux.conf is searched for first on eMMC, or on SD card, but steps prior to U-Boot loading Linux are still on the eMMC. Consider that the command line flash argument is mmcblk0p1 for eMMC (the first partition of eMMC used for rootfs), or mmcblk1p1 (the first partition of the SD card used for rootfs)…no other partitions are given an option as to where to install. I suppose it might be possible to alter this behavior, but it is not set up to do so with the flash software provided.
