xavier nx模组外挂SD卡识别不了，请问是什么原因？电压都正常3.3V
Please describe question in English. Some simple tests will be helpful such as: How many kinds of cards did you test? Is it on dev kit or your custom carrier board? How many module did you test with?
There is no update from you for a period, assuming this is not an issue any more.
Hence we are closing this topic. If need further support, please open a new one.
Thanks
