Are you aware of a cold start problem on the Atom Z520 embedded Cpu?

428 Views

Hello,

We make a motherboard that uses an Atom Z520 Cpu.

The motherboard works perfectly we produce large series.

However we encounter problems on some, these cards are designed to operate at -40 ° C (the Atom Cpu is an industrial model) and we note a cold start problem the card does not start and returns several messages to us (SMM init failure or microcode update failure) we suspect the CPU.

Anyone know of this problem?

thank you
