Hi,everyone,
I have to use two C6678 as PCIE EP device to communicate with one HOST(Windows OS,as RC). I can already make one c6678 commuticate with host(include driver) through PCIe.
But when i pulg two c6678 board(two c6678 programmed same code ) to host., in windows OS i can not enumerate any devices!
Now, i have the list infomation:
1. I use the pdk example code
1. Modifde one c6678's BAR address, no effect
2. Modifde one c6678's vendor and device ID, no effect
3. The code
/* Wait for link to be up */ pcieWaitLinkUp(handle);
can pass; so that Link have been up, Debug 0 LTSSM state is 0x11. But when the HOST power up , i find LTSSM state is 0x00, the link have been down.
What's wrong with the Link? Why i can not pulg mutiple c6678?
