Okay. Got that far. jumpered pin16 LDR to VCC and plugged in the USB.
Got ST device in DFU Mode in device manager.
Followed the instructions from here: USB Device Not Recognized - Cerberus, Cerb40
2) Erase the part and load TinyBoot
Run the DFU Tester.exe program from the programs(x86)/STMicroelectronics/software/DfuSe/BIN/STDFUTest.exe
- click Protocol tab at the top
- click Create from Map
- click Erase
- click Load DFU file
C:\ProgramFiles(x86)\GHI Electronics\GHI OSH NetMF v4.2\FEZ Cerb Family\Firmware\TinyBooter_4_2_5_0.dfu
- click the "Download" radio button
- click GO.
Reboot the part. Should ping TinyBooter.
Now the device does nothing unless I power it up in bootloader mode.
Which tool do I use to load the cerb boatloader .dfu?
