uart real com1 can not be opened by windows 10 putty

[ear]

Please, help.

we have developed a new shopping system based on UP CORE PLUS board (Intel® Atom™ x5 / x7 64 bits). The windows 10 device manager presents the UART COM ports and the virtual COM ports perfectly, no errors. We use a monitoring software, like Device Monitoring Studio or MObaxterm (minicom engine), to display data, and it works fine displaying data from real and virtual ports. But we need to interact with the real COM1 UART port using Python (pyserial), but it doesn't work, the port doesn't open. Using PUTTY windows, the problem is the same, it does not work when trying to open the real port, and the error code is 87. The virtual ports can be open witout problems. We think Python works when Putty does.

The issue is in windows 10 (home or pro tested). When the systems runs in ubuntu 20.04, the real ports UARTs  and the virtual ports work fine, all of them  (tested by cutecom).

We think there is a a driver problem. We have the latest UART drivers intalled:

serial-io-30.100.1631.03-win10-rs1-rx64-apl-signed-installer

Intel_Processor_Win10_HSUART_Sub_Drivers_64Bit

Please, we would appreciate any help

Thanks Carlos for your quick answer.

We run that tool before. The drivers are all the latest.

Any way, we will do it again and tell you...

Thanks

Carlos,

the Intel driver and support assistant tell us again that everything is updated in windows 10 pro for workstation (home versión tested before and the same issue)

Any help?

thanks

Hello, @ear:

Thanks for your reply.

We want to address the following questions to understand this situation:

Could you please clarify how many of the affected designs have been manufactured, how many are related to this situation, and the failure rate information?

Could you please let us know the part numbers of the processors related to this thread?

Could you please list the sources that you have used to develop the affected designs?

Could you please clarify if the designs have been verified by Intel?

We are waiting for your answer.

Best regards,

@CarlosAM_INTEL.

Hi again, here you hace your answers:

Could you please clarify how many of the affected designs have been manufactured, how many are related to this situation, and the failure rate information?

We are in a prototype fase, 2 identical windows 10 systems have been created, and both have the same issue. (windows 10 pro and home)

Could you please let us know the part numbers of the processors related to this thread?

UP CORE PLUS board (Intel® Atom™ x5 / x7 64 bits).

Could you please list the sources that you have used to develop the affected designs?

The windows 10 device manager presents the UART COM ports and the virtual COM ports perfectly, no errors. We use a monitoring software, like Device Monitoring Studio or MObaxterm (minicom engine), to display data, and they work fine displaying data from real and virtual ports. But we need to interact with the real COM1 UART port using Python (pyserial), but it doesn't work, the port doesn't open. Using PUTTY windows, the problem is the same, it does not work when trying to open the real port, and the error code is 87. The virtual ports can be open witout problems. We think Python works when Putty does. We have tried updating drivers, changing windows 10 version...

Could you please clarify if the designs have been verified by Intel?  The board is UP CORE PLUS, by AAEON, so we think so.
