Problems with DW1001-DEV in opening UART

Wireless Connectivity Ultra-Wideband

Hi
I’m having problems using a DW1001-DEV with UART as suggested in the firmware guide, I have two devices mounted on raspberry pi4b, one of the two dw1000-dev works perfectly on both devices and you can use the dwm “shell” when opening UART with minicom, while the other, if I try to open minicom, and try to send two ENTER, it remains stuck and gives no response

Hi @Riccsrdo
please try following:

  1. Update the Segger firmware on the DWM1001C-DEV boards (https://www.segger.com/downloads/jlink/ install it an then use J-Link Configurator to update it). There is a good chance thay you have olde SW in it which was a bit buggy.
  2. Double check if you have flashed all your modules with the most recent FW version.
  3. Double check the UART configuration: 115200, 8 bits, 1 stop bit, no parity, no handshaking

Hi, thanks for your response!
I tried updating it to the latest version available in the zip file, the one located in DWM1001/Factory_Firmware_Image, as well as the one located in DWM1001/Source_Code/DWM1001_on_board_package in the recovery folder, though it’s strange because the version is R2.0, while in the firmware guide it’s stated to be R2.1
Anyways, in both cases, it didn’t work as expected, it doesn’t seem to communicate in any way via SPI or UART, only via Bluetooth through the app.

Hi @Riccsrdo
I think that the R2.0 is the latest one.

It should normally work - check the wiring, especially DWM1001C reset signal. If the reset is tied to GND then you will be able to flash it but the program wont run.

During the flashing be sure that you have Erased the full memory.
