DFU bootloader fails after init packet #15

irarykim commented 4 years ago

Problem description:

Operations:

  1. Flash the Adafruit nRF52 Bootloader hex file(with SoftDevice) to PCA10056.
  2. Generate bootloader package file using adafruit_nrfutil from Adafruit nRF52 Bootloader hex file without SoftDevice.
  3. Update bootloader using adafruit_nrfutil, but it failed.

Environments:

OS: Windows 10 Pro 1903 Board: PCA10056 (nRF52840 D/K made by Nordic Semiconductor) adafruit-nrfutil: version 0.5.3.post12 (commit version) (use python 3.8 to generate exe file) Bootloader used: Adafruit_nRF52_Bootloader master v0.3.2 Shell: windows powershell (Runs as Administrator)

The log for generating bootloader dfu package:

PS D:\SW\E2\Debug\DFU> .\adafruit-nrfutil.exe dfu genpkg --dev-type 0x0052 --bootloader .\pca10056_bootloader-0.3.0-8-g3666e69-dirty-nosd.hex .\pca10056_bootloader-0.3.0-8-g3666e69-dirty-nosd.zip
Zip created at .\pca10056_bootloader-0.3.0-8-g3666e69-dirty-nosd.zip

The log for updating bootloader:

PS D:\SW\E2\Debug\DFU> .\adafruit-nrfutil.exe --verbose dfu serial -p COM13 -b 115200 --singlebank -pkg .\pca10056_bootloader-0.3.0-8-g3666e69-dirty-nosd.zip --touch 1200
Upgrading target on COM13 with DFU package D:\SW\E2\Debug\DFU\pca10056_bootloader-0.3.0-8-g3666e69-dirty-nosd.zip. Flow control is disabled, Single bank, Touch 1200

Failed to upgrade target. Error is: WriteFile failed (PermissionError(13, 'The device does not recognize the command.', None, 22))

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.

It is my mistake.. I should try make BOARD=pca10056 SERIAL=COM13 dfu-flash command showed in https://github.com/adafruit/Adafruit_nRF52_Bootloader#option-1-build-with-makefile
