Today I updated my old (non gadgeteer) FEZ Cobra I with the latest firmware.
Since doing that, the connected (also old) 7" display nog longer shows any text.
I think I remember something about the need to load older firmware, but cannot find the link on this website anymore.
I need to do an update of existing hardware in the field.
Maybe any of you guys can help me out?
Since you need to update tiny booter and reconfigure LCD, a unattended update in the field will not be possible I think.
After updating the FW you need to configure the display with FEZCOnfig, because the later firmwares have no display configured by default.
This might be possible by code as well, but I not sure about this.
From GHI NETMF V4.1 SDK I loaded FEZ Cobra I with Tinybooter v4.1.6 and firmware v4.1.8 and that works fine. Used FEZ Config for that and selected the 4.1 loader and firmware instead of the 4.2 defaults.
I wonder, since FEZ Cobra I is based on EMX, is it possible to run FEZ Cobra I with the latest firmware (220.127.116.11)? Would that be a better idea instead of staying at the V4.1 firmware ?
@ JdV - As a Cobra uses the EMX SoM, it will accept the newest firmware. The newer 4.2 SDK releases removed the screen being active by default so you will either need to use the FEZ Config to set the screen parameters or incorporate the LCD Config code into your program to set the LCD screen.
