I flashed SD card with balena and rufus its same

Is SD card flashed properly?
You’d need to do this from Linux, but assuming the SD card is “/dev/mmcblk1” (alter if not), then what do you see from:
sudo gdisk -l /dev/mmcblk1
The reason I ask is that in your partition listing I see no mention of GPT versus old style BIOS scheme. A typical reason for failure of a GPT scheme falling back to old style BIOS is from using tools which predate GPT (e.g., fdisk was meant for BIOS style partitions, while gdisk is meant for GPT partitioning). I have not looked at the distributed images which are used with Balena, but I suspect they should all be “GPT with a protective MBR”. This is what I hope to see from the gdisk command…that it is GPT with a protective MBR. If not, then this would account for the “`Invalid GPT Partition” error message. If this is in fact GPT, then there is something else going on.
In this case the problem differs from the SD card itself being wrong. Can I verify that this is a dev kit and not a third party carrier board? Also, could you post the complete boot content from a serial console boot log? See:
https://www.jetsonhacks.com/2019/04/19/jetson-nano-serial-console/
Basically we need context of what went on in boot from start up to the error point. In combination with this you’d also need to mention the exact image release version you used.
Is there any source code of bootloader which print PT: Partition TBC NOT found ! ?
Is that the complete serial console boot log? Is this a dev kit or does it use a third party carrier board?
I do see a function which would print this (passing TBC as a string argument) in a couple of places, but I do not know anything about the TBC partition so it is hard to say what the partition does without looking it up. Someone from NVIDIA may know what the significance is of the TBC partition and why it might not be found (meaning how it would come into existence during flash, but fail).
Its complete log and this is dev kit
Please find a x64 ubuntu host and use sdkmanager to flash your board.
Nano isn’t detected by sdkmanager
There is no update from you for a period, assuming this is not an issue any more.
Hence we are closing this topic. If need further support, please open a new one.
Thanks
Do you put your nano into recovery mode? Is your ubuntu host a VM? Do you use power jack to power the nano or micro usb cable?
