I'm experimenting with building the watch firmware with arduino-cli in linux
I thought I had it working then things started dieing
apparently a newer version of arduino cli is checking size

is 10287947 should be 15614691

in

Size is worng

Sorry if I am mistaken if so please let me know if I got it wrong

Dear Aaron, thank you for this excellent work 🤗
Do you know is there is an alternative to D6Flasher that would run on a PC?
(I don't have an Android device with bluetooth.)

Hi,

Like your videos about D6Flasher and DaFlasher, thanks for sharing!

I could use your help in flashing Arduino firmware in my Nrf52832 module (E104-BT5032A nRF52832). After I want to shift to an Nrf52832 Smartwatch.

Flashing bootloader and softdevice via OpenOcd/ST-Link works OK and:

• flashing Micropython@fanoush via NrfConnect works OK (details below).
• flashing Micropython@fanoush via your D6Flasher App works OK too.

But uploading an Arduino hex file compiled for NRF52832 using NrfConnect or D6Flasher App fails every time. NrfConnect disconnects after some seconds without uploading.

I guess the bootloader+softdevice that works for micropython is not right for Arduino.

I have been reading for days and experimenting with different bootloaders, different softdevices, but without success. The BLE upload always fails.

Would be great if you could point me in the right direction, I’m not sure where my mistake is.

Greetings.

DETAILED INFO

• OpenOCD command on Apple iMac:
  iMac19-9:espruino gerard$ openocd -f interface/stlink-v2.cfg -f target/nrf52.cfg -d2 -c init -c "reset init" -c halt -c "nrf5 mass_erase" -c "program s132_nrf52_6.1.1_softdevice.hex verify" -c "program dsd6_nrf52832_bootloader-0.2.11-3-gfb847b9-dirty-nosd.bin verify 0x78000" -c "flash write_bank 1 dsd6-uicr.bin" -c "flash banks" -c reset -c exit

• AdaDFU device appears in NrfConnect App, after connecting, I can upload the micropython binary

• the micropython binary works fine using Webbluetooth in Chrome browser.

• AdaDFU device appears in D6Flasher App, after connecting, I can upload the micropython binary

• the micropython binary works fine using Webbluetooth in Chrome browser.

Thanks :)
