Failed flashing t210ref.
I don’t k now the cause of this particular failure, but I see at least some of the USB communications had to have succeeded since the log shows “Boot Rom communication completed”. Is this a VM host? VM USB tends to be difficult to get to work.
may i know which JetPack version you’re working on?
could you share the commands that you flash cboot.bin
I find that JETPACK3.1 flash cboot.bin.encrypt which is from cboot.bin and is not generated from u-boot source code R28.1 to EBT partition of my TX1 board,while JETPACK3.0 flash u-boot-dtb.bin which is generated from u-boot source code.I find cboot is the bootloader of TX1 whose system is flashed by JETPACK3.1 and the cboot include u-boot which version is U-Boot 2016.07-g0ce7ca2.
We use TX1 as a module of our product and we should reduce the bootloader time.So,I wander if there is source code for cboot.
no, cboot and uboot are different.
please refer to more details in the Boot Loader chapter of the NVIDIA Tegra Linux Driver Package, 28.1 Release Development Guide.
also, we did not public source code for cboot.
Jerry,thank you very much!
Jetpack vesion is 3.1.
So, I can skip flash cboot failed in install jetpack guide right?
The cboot can be flash before?
I also found cboot.bin in /bootloader/.
could you please share the full flashing message of your JetPack3.1 installation progress.
I have the same problem with exactly the same message when I boot TX1 using JetPack 2.3.1 on Ubuntu 14.04. Does anyone solve this problem?
