I got the hardware kit of the SIMtrace.
It booted successfully (I guess because I got the red light on the board).
Then I connected the jumper to the test pin (I read the user manual so I
act according to it). When it booted up, I got green and red lights.
After I tried to power it on again without the jumper, I got nothing (no
light) and no recognition with lsusb command.
I tried to connect the board to other PC, and still no lights.
How can I fix it?
Thanks in advance!
My name is Richard Hughes and I work for Red Hat. I'm the maintainer
of fwupd, an open source firmware update system designed for Linux.
We're updating thousands of devices every month safely and securely
using the fwupd and the Linux Vendor Firmware Service. I'm also the
guy behind the OpenHardware ColorHug device, so I'm particularly
interested in making firmware updates easy to apply on open source and
free software devices. I see SIMtrace is using DFU, and fwupd can
already talk to DFU-using devices using the libdfu library so I don't
think any actual additional code would be required in fwupd. For your
device, it would just be creating a cabinet with the required metadata
If this is interesting, please see http://www.fwupd.org/ or email me
back for more details. I can create you a dummy account on the LVFS if
you'd like to upload some test firmware. If your device doesn't have
any firmware updates, and you don't plan of issuing any, please
disregard this email. Thanks for reading!
