Hey everyone, encountered a weird issue with the board recently. Whenever I upload a new sketch after updating the firmware to the version provided to me by the U-Blox team my board after a couple seconds enters boatload mode and the code stops working. Any idea as to what could be causing this or any viable solutions?
Could do with more information really:
a) which board are you working with?
b) how are you uploading the firmware (USB / some programmer)?
c) what is this firmware provided by the U-Blox team?
It does sound like your board is crashing and rebooting itself. Can you flash a basic example sketch to it (e.g the well known blink) and does it work OK then?
Hey thanks for the answer. I'm working with MKRNB1500. I'm uploading the firmware with the steps covered in the Firmware upgrade for UBLOX SARA-R410M-02B on the MKR NB 1500 #2 which include soldering USB cable on the board. It is firmware version [SARA-R410M-02B-03-L0.0.00.00.05.12_A2.19_IP.zip]. Basic sketches work but anything with the SARA-R4 seems to cause the bootloader to go off after a couple seconds.
So you struggling within the firmware update process? You have to describe your issue a little bit clearer to get some help here.
