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 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
