I am trying to enable PCIe on a TX2 module with custom carrier according to this thread:
Some very clear steps on how to apply this update would be helpful. I am unable to flash u-boot due to an error. I am attempting to flash via the devkit carrier.
I have tried several variations, but my core steps were:
- update Linux_for_Tegra/bootloader/t186ref/BCT/tegra186-mb1-bct-pmic-quill-p3310-1000-c03.cfg with file from thread
- make u-boot in Linux_for_Tegra/sources/u-boot/
- copy u-boot.bin to Linux_for_Tegra/bootloader/t186ref/p2771-0000/500/
- flash with the command provided in the thread:
sudo ./flash.sh -r -k EBT jetson-tx2 mmcblk0p1
This command runs through a lot of packaging steps, but at the end, it produces this error:
