I have received my first G120HDR boards today and wanted to start clean by updating the devices.
White screen (TE35 attached) at startup, and show’s in device manager as "GHI Boot Loader Interface(COM27)"
Started the G120 updater, update, all ok (screenshot a)
Starts up with version 188.8.131.52 “Waiting for debug commands…” on the TE35
and shows in device manager as “Debuggable .Net Micro Framework Device” (see screenshot)
I run theG120 updater from "C:\Program Files (x86)\GHI Electronics\GHI Premium NETMF v4.2 SDK\Firmware Update"
Connect the G120, pull LDR0 and LDR1 to GND and reset the G120.
G120 reboots and show’s TinyBooter v184.108.40.206 “Waiting” on the display.
At this point the “Debuggable .Net Micro Framework Device” is removed in the device manager BUT no other device is showing up?
I woul expect the GHI Boot Loader Interface on a COM port but no device showing.
Then i pulled LDR0 and LDR1 to the 3.3V and execute step 5 on the G120 Updater but get the message "Can not connect to the device etc etc"
What looks normal to me because there is no detected device.
Exact the same as PCB B
I already removed the drivers, switched USB ports, used a different cable, added external power source.
The actual boot loader look installed ok because PCB A was showing as "GHI Boot Loader Interface(COM27)"
I use 2.10 for LDR0 and 0.22 for LDR1.
What else should i check? Thanks.
