Re: Node firmware update using DFU by software

Ok, I get it.

But I just found this post. It uses the Rpi to flash and debug using openocd via the SWD connector. Using a Rpi Zero plugged to the node, this is pretty cool and cost-effective..

Re: Node firmware update using DFU by software

There is a gateway (A8, Linux) that allows integration of custom open nodes using usb connector. I will be testing it on private testbed in dev. For over the air upgrade, that would be nice. But this requires that the bootloader that is able to upgrade from external memory where the new firmware is ...

Re: Node firmware update using DFU by software

Great news !
This exactly why I looked into it, having an autonomous testbed so I can test it within Inria's IoT-Lab testbed.

Re: Failed to read data from EEPROM!

From what I understand from the code, you should type d and reset your board.
This will write a 1 on adress 0 in the EEPROM, which is then tested in the self-test.

Give it a try ;)

Re: Node firmware update using DFU by software

Well, I have something that works. New command 'u' lets the code enter in DFU mode. Give it a try from this fork and let me know.

Re: Node firmware update using DFU by software

Ok great, I will give it a try and let you know.
BTW, I noticed that flashing using dfu-util with the option -R does not reset the device after programming, and had to use the -s :leave option instead...

Node firmware update using DFU by software

Hi, I recently update the LPS node firmware using DFU over usb according to the documentation. To enter the BSL, one has to reset while pushing the DFU button. I am interested in another way of entering the BSL by software. Once a character received on the serial (say 'b'), the code jumps to the boo...

Re: Multiple measurements in reference system - Raw Data

Hi Arnaud, I understand that the position estimation results for the 4 static positions reflect stability of the position estimation filter. But what I am interested in are the raw range measurements corresponding to each position. Even the ground truth is not very accurate, such data may be useful ...

Multiple measurements in reference system - Raw Data

Hello, I would like to know if raw ranging data is available for the multiple measurements that were made with the reference system ( here ). Raw measurements are only available for the hovering case with Crazyflie: (x,y,z) = (5.00, 1.50, 0.76). It would be nice to have it for some offline tests loc...
