Option 2: Enabling PCIe Serial Port on TGL Intel NUC
|
||||
====================================================
|
||||
|
||||
If there is no internal serial port header on your NUC; you can enable PCIe serial port to debug the issues effeciently.
|
||||
As you know,most of the NUC don't have PCIe interface,but have NVMe M.2 interface;so the additional M.2 to PCIe adaptor is needed to
|
||||
enabnle PCIe serial port on NUC.You can buy the `adaptor

|
||||
