I am working with with Towerbaord (LS1021A) and try to access to MMIO registers on a mini-PCIe card (32 bit device) . With existing device tree I get a bus error during accessing to MMIO registers (using UIO framework mmaped to user space). Howto configure device tree to access to a 32 bit PCIe device?


Thank you.
