Unable to burn bootloader from Arduino IDE

ExpLoRer
1

Hello,

i would like to update the bootloader of my boards ExploRer (rev 5b) to latest version to benefit from the blue led when i’m in bootloader mode. I have version 1.6.11 board description files

I have a J-Link EDU from Segger to program it and there is no way i can ‘Burn Bootloader’ from Arduino IDE, here is the message

Open On-Chip Debugger 0.9.0-gd4b7679 (2015-06-10-22:24)
Licensed under GNU GPL v2
For bug reports, read
http://openocd.org/doc/doxygen/bugs.html
debug_level: 0
adapter speed: 500 kHz
adapter_nsrst_delay: 100
cortex_m reset_config sysresetreq
Error: unable to find CMSIS-DAP device

So i’m trying to burn it with J-Flash Lite from segger.

Can you confirm what .hex file (from what directory ) i can use ?

i was about to use ;
\Arduino15\packages\SODAQ\hardware\samd\1.6.11\bootloaders\zero\samd21_sam_ba.hex

Regards

Dear @laurentchivot,

I would recommend upgrading to latest stable release 1.6.19
Follow the steps here to change to the new download urls. 1.6.11 is the latest in the combined url.

This is the Arduino Zero bootloader. Works fine on the explorer. Same Microcontroller.

But with the Explorer bootloader can be found here:
\AppData\Local\arduino15\packages\SODAQ\hardware\samd\1.6.19\bootloaders\explorer\samd21_sam_ba_explorer.hex

Best Regards,
Jan
