I have flashed a SD card with the Ubuntu operating system. I went to plug it in where the documentation told me to and I find no SD socket. It isn’t there. Is there another place for it. I purchased it from Amazon about two years ago. It was supposed to have more memory and does this affect the SD socket position?
Hi,
This means you are using a emmc module (internal 16GB storage) and with a custom carrier board there. The thing you are using is not a NVIDIA developer kit.
Please check with the board vendor for how to flash their custom board.
Just some added info: Models with eMMC boot differently than models without it. There is QSPI memory on the module itself of an SD card model (developer’s kit) used for initial boot; on eMMC models this same thing is instead in partitions of the eMMC. The flash is different (slightly). You’ll normally be booting from eMMC.
Modules have various pins which can have multiple functions, and this depends on how they are set up. A custom carrier board (which this would be) most likely has a different layout compared to the developer’s kit carrier board. The way the module is told to route pins is through firmware (specifically the device tree). The only one who knows what modifications there are will be the manufacturer. Sometimes a manufacturer will say this matches the NVIDIA layout and that you can use NVIDIA’s flash software, but more often the manufacturer will provide flash software. That software will take the form of either a patch to NVIDIA’s software, or else a rebranded flash software which is mainly a change to the device tree. Regardless, you have to check the web site of whoever made this to look for flash software.
There is a lot which will be the same between a developer’s kit and the eMMC commercial module version, but flash is not likely one of those.
