Problems with Flashing the LPS Anchors with DFU

[smarka]

I am using the BitCraze VM and updated all projects with the icon. I can connect to the anchor with picocom and the report looks OK. However, I totally fail with flashing the anchor whether I follow the video or the wiki instructions - I fail with the same error message:

bitcraze@bitcraze-vm:~/projects/lps-node-firmware$ sudo make dfu
dfu-util -d 0483:df11 -a 0 -D bin/lps-node-firmware.dfu -R
dfu-util 0.5

dfu-util does currently only support DFU version 1.0

Bump.
I am also having this issue.

Hi, it seems to me that
"

"
does not affect the proper functioning of the node. If you look carefully at the video at approximately time 2:28, he also has the same message.

But, maybe wait for an official explanation.

@JNLance: yes the "can't detatch" error does not affect functionality. DFU-utils has a bug that prevents it from reseting the node. We have started developing a tool to flash the nodes (https://wiki.bitcraze.io/doc:lps:tools# ... ation_tool) that can detach properly and reset the node.

@smarka: You need dfu-util 0.8+ in order to flash the node with dfu. DFU-util 0.8 comes by default with Ubuntu 16.04 which is the recomended system for the early-access LPS. We have not yet updated the virtual machine this version of Ubuntu. If you want to flash with the bitcraze VM I found a PPA that has dfu-util 0.9 for Ubuntu 14.04 (Trusty): https://launchpad.net/~tormodvolden/+ar ... ter=trusty

Hi Arnaud @arnaud

I met the same problem and I tried the dfu-utils you mentioned. Currently, I'm using dfu-util 0.9.

I open the bitcraze VM, and connect LPS node via USB. I can found the devices by type

Code: Select all

lsusb

It shows,

Bus 001 Device 006: ID 0a5c:6412 Broadcom Corp.
Bus 001 Device 009: ID 0483:5740 STMicroelectronics STM32F407
Bus 001 Device 003: ID 0e0f:0002 VMware, Inc. Virtual USB Hub
Bus 001 Device 002: ID 0e0f:0003 VMware, Inc. Virtual Mouse
Bus 001 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub

Then I tried

Code: Select all

sudo make dfu

It shows,

fu-util -d 0483:df11 -a 0 -D bin/lps-node-firmware.dfu -R
dfu-util 0.9

Do you know where goes wrong?

Thanks

I tried it on my own Ubuntu 14.04.
It also has this "dfu device not found" problem.

[JNLance]

@chuhao
Did you set the anchor into DFU mode before "sudo make dfu"?

[chuhao]

@JNLance
I set the anchor into DFU mode, by press dfu button once and press rest button once.

It seems that your node is not in DFU mode. Your lsusb command shows the firmware VID/PID. The DFU bootloader will appear as follow:

Code: Select all

$ lsusb
(...)
Bus 003 Device 014: ID 0483:df11 STMicroelectronics STM Device in DFU Mode
(...)

You should keep the DFU button pressed while you are pressing and releasing reset. In DFU mode none of the left LEDs should blink or be light up (the right LED are the radio and they can continue to blink).
