Windows 10 IOT device driver development: LPC interface support for writing ISA device driver

Hi,

I am new to windows device driver development. In my project we are using PCA-6029 (i7 with H110 chipset) board for development. It supports windows 10 IOT enterprise LTSC, we have to develop a ISA device driver. ISA device is a memory module, we need to access the memory from PCA 6029 board through ISA bus. (mapping ISA device memory to PCA 6029 cpu board).

In PCA-6029, ISA interface is connected through LPC module (Fintek F85226AF-I). Basically LPC module act as bridge between processor and ISA interface (LPC and ISA). Please find attached image for reference.

where I have to begin writing a driver. (I have been studying windows 10 KMDF driver frame works and created build setup).
For writing ISA device driver, I need the LPC to ISA bus support in windows 10. whether that support will be there in windows 10 IOT or need to write a driver for fintek bridge ic (LPC to ISA). How can I verify that support in windows 10 IOT.

  1. Any driver available for that LPC module (fintek bridge)?.
  2. How processor can communicate to that LPC module. Do we have supported APIs in window10 IOT.
  3. Initial BIOS setup (ref:PCA-6029_User_Manual_Ed1) also not there for fintek LPC module. Then may it initialized by default?
  4. How enumeration will be happened when we connect ISA device to the ISA port?.

Basically my doubt is how can I memory map the slave ISA device to PCA 6029 cpu board. Where I have to begin.

    You might want to reach out to OSR to see if they have any input into the driver you want to develop: http://www.osronline.com/ and https://www.osr.com/osr-learning-library/
