Port is ok.. it shows in device manager, board: one pin is blinking yellow and another steady green, but I always see the following error when
trying to upload the blink example for testing:
from Arduino IDE:
the error is: avrdude: jtagmkII_initialize(): Cannot locate "flash" and "boot" memories in description
And from B4R the error is:
System wide configuration file is:
"C:\.........\Arduino15\packages\arduino\tools\avrdude\6.3.0-arduino17/etc/avrdude.conf"
Using Port : COM7
Using Programmer : arduino
Overriding Baud Rate : 115200
avrdude: ser_open(): can't open device "\\.\COM7": Access is denied.
avrdude done. Thank you.
Failed uploading: uploading error: exit status 1
Any help appreciated
