You are trying to access UART, but currently you can only access UART1, right?
Yes, i think that's customer's case. I do not have their RTOS code though.
We are currently working on obtaining more information regarding this post. As soon as we have an answer we will post it here.
Hi. From the Quark datasheet, 18.5.10, the diagram shows that Bit 0 of this BAR0 is hardwired to be 0. As per the PCI spec, if the bit is 0 then the value in this BAR will be a memory mapped address. If it is 1, then the address is in I/O space. Same for BAR1.
