2025/05/11 14:22:42 main.go:30: Access is denied.
getting access denied....not sure why....any ideas?? I am the administrator on this system. Thx
I can upload the ymodem.ino example and get �8� and blue led blinks a few times and then goes off. So I assume voice module is ready for file uploads...
There are reports of false positives regarding virus checkers. Maybe try turning off yours (probably Windows) to see if that works.
THX! I did check that , but will try again..
also w/cmd I get thsi error:
C:\Users\XXX\Desktop\ndp120>./syntiant-uploader-win send -m "Y" -w "Y" -p COM25 mcu_fw_120_v91.synpkg
'.' is not recognized as an internal or external command prompt,
operable program or batch file.
my system:
Win 11 home
|Processor|AMD Ryzen 7 PRO 4750G with Radeon Graphics 3.60 GHz|
|Installed RAM|32.0 GB (31.8 GB usable)|
|System type|64-bit operating system, x64-based processor|
so I followed the arduino update firmware doc https://docs.arduino.cc/tutorials/nicla-voice/user-manual/#step-files.
I 'F' formatted the voice drive. 'L' is empty. But now I still can't upload the new firmware using the provided syntiant uploader in the files found here : this .zip file
went into win defender and gave the syntiant-uploader-win all the special privileges , disabled virus and firewalls, and disabled norton and whatever else I could find. Still nothing more than below (except no access denied!):
I have arduino 2.3.2

I figured it out! Sooooo Simple.....you can't have the Nicla COM port open in arduino IDE when trying to upload new firmware! So for everyone else having the same issue...close the arduino IDE before using powershell to upload to Nicla device. The error "ACCESS DENIED" is because I did not have COM access, not due to virus blocker or win defender ... ugghhhh....
ADMIN: please add to section in Nicla Voice User Manual section on NDP120 Processor Firmware Update #3A) Be sure to disconnect COM port or close arduino IDE to Nicla device before uploading new firmware.
Thank you!
