I have an SD card adaptor for M.2 Key E. I tried using this with the Jetson Orin Nano I have in an A603 carrier, but it won’t boot. Is this supposed to work, or does only the Key M slot support booting?
Hi there,
I was also looking at this,
there are 3 other hits on the git hub for "https://github.com/NVIDIA-Jetson-Nano-Boot-from-USB3-SSD?

Currently A603 only supports booting in SSD or USB flash driver.
