imx287 board the dll is copied into Windows folder then gets lost after board reset

[kvrivishvilin9]

Dear community,

I have been developing the software to be deployed onto imx287 board. The purpose of the software is control of wellpro 8025 RO module with Modbus RTU. Therefore I use certain modbus libriry dll which provide me methods to interact with the wp8025ro module. The issue is after the app is being deployed onto the board it(imx287) cannot locate the 'libmbusmaster.dll file' which I copied into the Windows folder on the device as it is mentioned on https://learn.microsoft.com/en-us/previous-versions/windows/embedded/ee488148(v=winembedded.60)

After the dll is copied into the windows folder of the board imx287, then I reset the device it gets missed from the folder. Could anyone kindly provide any directives to take me into understanding of the issue?

Faithfully,

Nikoloz.

Dear forum readers,

The dll of x86 architecture has been accidentally added to project, whilst the dll native to ARMV4i CPU was needed. After I replaced x86 dll to ARMV4i CPU native the application deploys and runs on the board i.mx287. Please see the pictures I attached.

Hello,

Are you referring to the dll file which I copied into two locations: windows folder and SD card both on the imx287 board? Could you please expose me to details? How to make files build in the same kernel?

Faithfully.

Hello,

Both files are not building in the same kernel, the same kernel is needed it when you copy dll.
