Hi team,
My customer use C6655 L2 EDC function.
They are using a timer to call IDMA to move data from and to the same address. In the timer interrupt function they used IDMA to read/write all L2 memory. This action can refresh the EDC checking data area.
But there found if they use PCIE or EDMA or CPU to write the same area there maybe data conflict happened.
Like this:
IDMA read -> PCIE write-> IDMA write->CPU read
CPU will read the old data, not the PCIE write data.
Do we have any method to avoid this? thanks!
BR,
Denny
