Hello again!

The man page tells you how to proceed in this case.
You can not "select" the chipset with the -c parameter but only the
flash chip. All of that is documented...

BayTrail Soc device 0f1c does not work

Hi Stefan,

thank you for your reply.

You are right. In the man pages I found the switch: laptop=force_I_want_a_brick and no I get:

Multiple flash chip definitions match the detected chip(s): "MX25L6405", "MX25L6405D", "MX25L6406E/MX25L6408E", "MX25L6436E/MX25L6445E/MX25L6465E/MX25L6473E"

Next week I will check what for a chip is used in the contron COMe-mBT10 BayTrail module.

Best regards,
Alexander
