Hi
In our system we are using an LS1026A connected to a device by PCIe. The LS1026A is acting as RC, and the device as EP. We are running vxWorks RTOS.
Accesses from CPU to the device is working correctly. But when the device is trying to access the CPU RAM it looks like it doesn't work properly.
We configured an Inbound memory window at 0x88000000-0x8803FFFFF (4MB space) - the physical address space of the shared memory. We also configured the EP to this address space.
0x900 = 0x80000004 = INBOUND | REGION #4
0x904 = 0x00000000 =MEM
0x908 = 0x80000000 = ENABLED ADDRESS MATCH MODE
0x910-0x90C = 0x00000000_88000000 = REGION BASE ADDRESS
0x914 = 0x883FFFFF = LIMIT
0x91C-0x918 = 0x00000000_88000000 = TARGET BASE ADDRESS
Is there any other configuration we need to do to get it to work?
Is there any way to monitor the read attempts from the EP? to validate there are such an attempts
Do you have any suggestions?
Thanks!
