Description
Bought this IOCREST M.2 (PCIe 3.0) to 5 Ports (You can get them cheaper) and tried to make it work with cm4 4GB
Already increased the BAR memory, but I still got this BAR 0: no space for [io size 0x0080]

At this point I have no idea how to go further with this.
Confirmed that it works - connected to windows PC and it shows HDD.
