I am using core version 0x020F5B14 (register 0x54).
Register 0x58 is fixed i guess ? It holds 0xD073CAFD.

Hi,

I was notified about this patch recently, unfortunately I was not on CC
on the original submission, so I was unable to review/test this patch.
Nice catch though, thanks.

Which version of the core do you use ? Can you also share value of
register 0x54 and 0x58 ?

Thanks
