IRQ stack placed in DDR using IMX6SL

Hello community,

Our board is crashing after boot-up and when the code starts accessing the EIM bus. This happens the moment that interrupts are enabled. The team believes that the information that is coming back on the EIM bus is corrupting the IRQ stack memory.



We don’t have this issue on the eval board that is using a imx6sl. That eval board uses a different chip that has the GPU and EPDC (MCIMX6L8DVN10AB). Our board that uses imx6sl that has no EPDC unit (MCIMX6L3DVN10AB).  Is there anything that we should know about the two devices that might affect the EIM of the processor when there is no EPDC? Any tips on solving this issue would be appreciated.


The OS is eCOS.
