Dear All,
Recently I got another issue with DM8148. I tried to connect PCIe to IDE bridge card based on JMICRON chipset to DM8148 and found out that does not work. It gets initialized (although there are some errors during I/O mapping due JMICRON conf regs being limited to 16bits) but it does not see any drives connected to it. This board is visible for lspci and I can see the configuration space of IDE bridge chip but ATA device detection always fails.
Here are questions:
1. How to set up I/O mapping in a way so it ignores 16 MSB?
2. Is there any limitations to PCIe RC mode on DM8148 which would prevent the usage of such boards?
3. Does anyone has a successful experience with PCIe to IDE bridge on DM8148?
Also I'd like to note that the same EVM fails to boot with RTL-based GigE adapter and fails to detect USB3.0 PCIe board on NEC chipset.
