Hi Denys, We are using sitara u-boot and kernel coming from meta-ti thud branch.
We didn't had this problem before with daisy branch and RAM configuration in u-boot is not changed Is there any configuration/setting that you want me to share with you?

We are wrapping up our Thud support. But it was used in our products for about a year with rigorous testing and we haven't seen anything like that on any of our platforms. This does look like some memory corruption - are you sure you have all the timings correctly? Have you also switched any of the low-level components, like U-boot, Linux kernel, etc.?
