Hi Zahra,
Yes, I used the 6-pin serial port header. Also, make sure the microcode header(s) you include correspond to the CPUID of your processor. The E3825 and E3826 use different microcode headers, so M0130679901.h will not work for you.

Please keep the coreboot mailing list CC'd. I haven't done anything with Minnowboard in several months and others may be able to help.

Hi David 

Thank you for your help.
I extract your file and got M0130679901.h as Microcode but my board does not work it did not show anything. 
I use E3825.
In previous notes, you told "My guess is that you don't have CONFIG_ENABLE_BUILTIN_COM1 selected
(under "Chipset"), which is an option you have to set in addition to
the stuff under "Console."
but in your config, you had not enabled this option.
Could you help me with this and Did you use   6 pins that are separated on board for console port?
I do not know what is my problem .it did not show anything log.

Thank you for your time.

Hi Zahra,
That header may be out of date

I had to manually download the microcode file corresponding to my
processor SKU from Intel. Use the link I sent you earlier to download
Baytrail_FSP_Gold4.tgz and see if the microcode headers included in
that tarball match your processor. The Atom on my Minnowboard Turbot
has a CPUID of 30679, so I needed to use M0130679901.h.

(note that the Minnowboard Max uses an Atom E3825, while the Turbot
uses an E3826 dual-core SoC or E3845 quad-core SoC)
