Description David Anders 2014-10-22 18:46:06 UTC 
During early releases of the UEFI firmware we ran into some issues of not having a method of forcing the UEFI firmware to be reset. to address this issue, we are changing the function of J7 to perform as a GPIO controlled jumper. the signal GPIO_S5_17 will be used as the input for this function. when the jumper is removed the GPIO will be reported with a active high value. when a jumper is place on the header, the GPIO will be reported with a low value.

schematic and board layout are complete. performing design review...
Comment 2 David Anders 2014-12-18 22:05:39 UTC 
design review complete, ready to order prototypes.

Updating assignee to new office e-mail address.
Comment 4 California Sullivan 2015-08-21 00:13:33 UTC 
I can confirm that GPIO_S5_17 is reported as active high with no jumper and low when a jumper is in place. However, I do not understand what other functionality there is supposed to be, so I cannot confirm anything further.

Hi Dave,

What opertaion BIOS should do if a jumper is detected in place? You mentioned "forcing the UEFI firmware to be reset". Could you give more detal ablout this?
Comment 6 AMarchini 2015-09-25 12:37:41 UTC 
I believe the idea is for the CPU to boot up with default UEFI setup. Handy if you accidentally disable the screen or USB.
Comment 7 David Anders 2015-10-27 22:40:04 UTC 
when jumper is in place, firmware will reset NVRAM to default state and save.

The code is ready and waiting for new Turbot board to test.
Comment 11 David_Wei 2015-12-08 05:38:06 UTC 
V0.84 Release will include this feature for MinnowBoard Turbot.

We are no longer tracking in Yocto Project Bugzilla MinnowBoard and MinnowBoard-MAX HW and firmware bugs.
