I’m first study with Arduino,and do as Arduino and OpenMV doc.
First,i have use Arduino IDE 2.3.3 and download Arduino Mbed OS Nano Boards 4.1.5，and then File—Examples—Nano33BLE_System—Nano33_updateBLandSoftDevice—Upload to device—and Serial Monitor to enter y,it can work well.
Second,i use this command"`C:\Users\kingfly\AppDatalLocal\Arduino15\staging\packages\bin\bossac.exe --offset=0x16000 --port=COM6 -i -d -U -R C:\Users\kingfly\AppData\Local\Arduino15\staging\packages\bin\firware.bin" to flashing fireware.
Third,this command work well,and show message
"Set binary mode
Version()=Arduino Bootloader (SAM-BA extended) 2.0 [Arduino:IKXYZ]
Connected at 921600 baud
…
Write 274252 bytes to flash to (67 pages)"and so on.
Fourth,After flashing this fireware,OpenMV can’t connect this board,and Arduino IDE also can’t upload anything,like example or other code,there will toast like this
“Sketch uses 284136 bytes (28%) of program storage space. Maximum is 983040 bytes.
Global variables use 44616 bytes (17%) of dynamic memory, leaving 217528 bytes for local variables. Maximum is 262144 bytes.
Waiting for upload port…
No upload port found, using COM6 as fallback
No device found on COM6
“C:\Users\kingfly\AppData\Local\Arduino15\packages\arduino\tools\bossac\1.9.1-arduino2/bossac.exe” -d --port=COM6 -U -i -e -w “C:\Users\kingfly\AppData\Local\Temp\arduino\sketches\CAE4AF1A6C08F10CB3B14D7BC80F4A87/Nano33_updateBLandSoftDevice.ino.bin” -R
Failed uploading: uploading error: exit status 1”
can anyone help me ,thanks very much
my port is COM6,and Arduino IDE can show Arduino Nano 33 BLE and COM6,but can’t upload anything and can’t flash anything,can you help me ,i’m a new Arduino lover
Hi, did you follow this? It should be working: Getting Started with OpenMV | Arduino Documentation
