Hey, I posted another issue the other day: AGX Xavier won't detect TF card? - #3 by jiapei1
And, please take a look at my dmesg here AGX-Xavier-SDCard-dmesg - Pastebin.com .
Anyway, if SDXC is working with Xavier AGX, there must be some issue with some particular brands/series.
Can you please help to let me know: which brands/series have been demonstrated working with Xavier AGX?
