HN-I error of CCN-504When using the CPUs, we find that errors (eg. hn-i.r_syndrome_reg0=0xF80000C 698280242) are detected in the hn-i module of the CCN-504 during memory read/write, and then we try to write 0xffffffffffffffff to the register hn-i.err_syndrome_clr to clear this error. However, the error occurs several seconds later. After repeated attempts to clear the error, we find that the hn-i.r_syndrome_reg0 still generates errors.
We are wondering if this error in the-504 would affect system stability? Or can we ignore it and use it?

Hi OliverI guess people on SoC Design and Simulation Forum can give some support to this problemMany thanks
Hi zhuhuaiyun,
As far as I know, CCN-504 TRM is confidential so anything publicly speaking about it is not appropriate so I suggest you create a support ticket through https://developer.arm.com/All%20Support%20Services if you have an entitlement to receive technical support on CCN-504.
Kind regards,
Toshi
