→ See skill: codex/usb-timeout-during-flashing

Q7: USB-A / Ethernet / HDMI not working after flash

Check file integrity (SHA256 checksums). For A60X carrier boards, ensure the driver patch was applied to Linux_for_Tegra/ with sudo and -r flag:

sudo cp -r <patch_dir>/* Linux_for_Tegra/

Q8: System crash / black screen after apt upgrade

Do NOT run apt upgrade on custom/third-party carrier boards. Debian packages from NVIDIA's server don't account for Seeed's custom board design. This can brick the device. Solution: re-flash JetPack using Seeed's guide.

Q15: Why can't apt upgrade be run on reComputer/reServer

Kernels and drivers are customized. Running apt upgrade replaces them with NVIDIA's generic packages, causing compatibility issues. Lock critical packages:

sudo apt-mark hold nvidia-l4t-core
