Unable to flash new code using Open Bootloader

mhbarnes commented 3 years ago

Upon receiving the dongle, I attempted to switch from the pre-installed UF2 bootloader to Open bootloader, since I wanted to use the nrf connect tools. I was successful in doing so, though now I am unable to flash new code or upgrade back to the UF2 bootloader. Whenever I attempt, I get the error "Timed out waiting for acknowledgement from the device" and "Attempting to use a port that is not open". Below is the output:

Possible causes:
- Selected Bootloader version does not match the one on Bluefruit device.
    Please upgrade the Bootloader or select correct version in Tools->Bootloader.
- Baud rate must be 115200, Flow control must be off.
- Target is not in DFU mode. Ground DFU pin and RESET and release both to enter DFU mode.

I was able to successfully flash the blinky LED code to the dongle using the nrf programmer, but when trying to flash anything else, I get the following error:

20:29:14.352    DFU failed: Error message for known extended error code from DFU target: The init packet does not contain a signature. This bootloader requires DFU updates to be signed.
20:29:16.367    Device not found due to failure during DFU

I am using WSL for Windows 10. Is there any way to reset the bootloader that I'm missing? Thanks in advance.

Hi, You may need to use the cmd like this(use usb-serial instead of serial):

nrfutil dfu usb-serial -pkg uf2_bootloader-0.2.13-44-gb2b4284-nosd_signed.zip -p <your-serial-port-name>

Doing so returns an error with nrfutil dfu:

@mhbarnes It seems you are using the newer nrfutil tool. The nrfutil version 5.0.0 works fine. Try to install the nrfutil 5.0.0:

pip uninstall nrfutil
pip install nrfutil==5.0.0

@caizelin I installed nrfutil 5.0.0, and tried installing the UF2 bootloader again. I hit a different error this time:

$ nrfutil dfu usb-serial -pkg uf2_bootloader-0.2.13-44-gb2b4284-nosd_signed.zip -p /dev/ttyS9

I ran into the same error when attempting to upload the blinky code as well.
