I tried to upgrade the OpenRTK330LI F/W from v23.01 to GNSS_RTK_INS v23.02 in the Aceinna code base by using the python driver v2.3.0.
https://developers.aceinna.com/code/apps
However, during the upgrade, some communication errors occur and the process stops. After the trouble, the python driver can not find the device. The green LED of EVK only flashes when the reset button pushed or the power on.
I tried to re-install the bootloader (v1.1.1) and the GNSS_RTK_INS APP (v23.02) in the code base by using ST-Link. The bootloader could be installed but the GNSS_RTK_INS APP could not be with the error message "File size is bigger than the flash memory size." I did not backup the original system image by ST-Link.
Where can I find the system recovery image of OpenRTK330LI ?

1. Turn the switch sw1 to the ST PROGRAM
2. Execute the command： python main.py -b 115200
3. If python driver is connected to the OpenRTK330L, upgrade again

Thanks.

I tried but the python driver still does not find OpenRTK330LI.

@Tomoji-Takasu Please provide openrtk330Li serial number and your email address. We will communicate with you.

@dai

Thanks.

I have exactly the same problem. When trying to update firmware online I got this error printed in Python driver:

Then the green LED will just flash rapidly, no orange or red LED.
I used ST-LINK to program OpenRTK330L_Bootloader_v1.1.1.bin, it is successful, but still green LED flashes rapidly.
Python driver can no longer connect.
I tried python main.py -b 115200 and setting switch to "ST program"

Mine is

Try to refresh the page. The automatic connect check may be past.

Looks like bootloader alone does not connect to developer.aceinna.com
I followed the instruction at https://forum.aceinna.com/topic/289/how-to-update-firmware-after-online-update-fails/6
To manually upgrade OpenRTK330L_GNSS_RTK_INS_v23.05.bin using --cli in python driver and now it connects after running python driver again after updating.

Hi, I also have an OpenRTK330LI unit that I would like to be able to upload new firmware to. I have looked at this thread as well as 2 other threads (https://forum.aceinna.com/topic/289/how-to-update-firmware-after-online-update-fails/11) (https://forum.aceinna.com/topic/295/please-fix-firmware-update-online-button/2), but all the different methods I have tried (

1. uploading the 23.06 prebuilt app on the website,
2. uploading a 23.xx bin or a VSCode OpenRTK330LI project bin via the online bin upload tool,
3. using the python driver command line to upload a 23.xx or custom project bin file,
4. Using PlatformIO within VSCode to upload a custom project bin file)
   do not result in a new firmware being successfully uploaded to the EVK board ("sync failed" error or "upgrade operation failed" error). Some support would in being able to upload firmware to this product would be greatly appreciated.
