I am referring QorIQ T1040 Reference Manual for my board T1042 where I want to reset the only pcie . But I could not able to find out how to reset the pcie .
Then I referred QorIQ T1040 Reference Design Board User Guide where I found out CPLD under that RSTCON2 register from which I can reset the PCIe
After memory mapping for the for RSTCON2 register on my vxworks platform I tried to write 1 to clear for resetting the PCIe , but not sure whether it got reset or not .
When I read default value RSTCON2 it was 0xFF ,but after writing also on pcie bit its still 0xFF . (no change)
I have few question related to my comments
1. How can I know CPLD is present on my target board T1042 since in refernce manual I could not find out anything related to that.
2.Is there any other way I can reset only pcie interface .
Thanks in advance
