For Blitzortung System Blue controller PCB 19.x. It might work on Blue Basic (PCB 22.x), but it is untested there.

Install through the station’s web page

On a station running stock Blitzortung firmware, open its web page, go to the firmware upload, choose image.bin and upload it. Stock firmware shows “Verified NO!” for this file; press Start Update anyway. The station restarts into DENKO Blue.

Or install over USB

Use this if the station has no working web page.

1. Back up and enter USB DFU

Connect the board’s USB port with a data cable. Hold BOOT0, tap RESET, release BOOT0; leave BOOT1 unpressed. Identify 0483:df11 and the Internal Flash target, alternate interface 0.

dfu-util -d 0483:df11 -a 0 -s 0x08000000:0x100000 -U backup.bin
shasum -a 256 image.bin

The result must be dbc2d4927f7c623fba760f01df0780ad7e895787aada50d127c9ba1e417a0183. On Windows: certutil -hashfile image.bin SHA256.

2. Program and read back

Program the raw binary at its start address with dfu-util, or with STM32CubeProgrammer at address 0x08000000, then read it back:

dfu-util -d 0483:df11 -a 0 -s 0x08000000 -D image.bin
dfu-util -d 0483:df11 -a 0 -s 0x08000000:434560 -U readback.bin
cmp image.bin readback.bin

Release BOOT0 and reset or power-cycle.

3. Connect to the network

Connect Ethernet with DHCP and open the assigned IP address.
