AM625: L2 cache size mismatch

Part Number: AM625
Other Parts Discussed in Thread: SK-AM62

Hi,

My customer evaluate the device using SK-AM62 with Linux SDK.
When they got CPU information with "lscpu" command, L2 cache size was shown as 256kB.

According to datasheet, L2 cache is 512kB. Why it is shown as 256kB?

Thanks and regards,
