I’m working on a project that requires using a long SD Card Extension cable for the SD boot card on the Jetson Nano. Unfortunately the Nano would not boot from an SD card at the end of the extension cable. The cable is flat ribbon about 18 inches long.
However after trying different SD cards I finally found one SD card that would boot in this configuration. I’m assuming that this may be becasue this SD card has a slower read rate. That’s a guess, but seems like the most likely answer.
In any case, I was wondering if there is a way that I can set the Jetson Nano to read the cards at a slower speed? I’m thinking that this might allow me to use the faster SD cards at the end of this cable by simply reading them at a slower speed.
This is all just a guess on my part, but I would like to try this if possible.
I’m running the Jetson Nono system OS (Bionic Beaver 18.04) that I downloaded from the NVIDIA site on getting started with the Jetson Nano.
Does anyone know if there is a way to set the SD card read speed to a specific value in this OS?
I’m thinking that if I can restrict the Jetson Nano to only using slower read speeds this may solve my problem.
