After clicking https://developers.aceinna.com/code/apps the python driver tries to load a firmware but fails. Now the green LED keeps flashing rapidly on the EVM and Python driver cannot find the board anymore.

Downloading Bootloader 1.1.1 and flashing using ST-LINK allows the Python driver to find the board, but it does not connect to https://developers.aceinna.com/ (UPGRADE button in https://developers.aceinna.com/code/apps greyed out)

From https://developers.aceinna.com/code/apps it allows you to download the bin file e.g. OpenRTK330L_GNSS_RTK_INS_v23.05.bin but there is no instructions on how to use ST-LINK to apply this downloaded file to the EVM.

I just paid like $500 to get this EVM 2 days ago from Mouser, and already got stuck while trying my best to follow the instructions. A single click of the "UPGRADE" button on https://developers.aceinna.com/code/apps on one of the "OFFICIAL" app caused all this trouble. Due to the complete lack of technical support I am seriously considering returning the whole thing to Mouser.

Serial number:

barcode (serial number?) 2075000294
module P/N 8350-3021-01
Information from https://developers.aceinna.com/devices/owned when it was working:
OpenRTK330L
SN: 2075000294
Part Number: 5020-3021-01
Firmware Version: 23.01
Last Connected Time: 2021-07-13 21:38:00

Please send me the firmware recovery file along with instructions.

If the green LED always flash, when it powers on, it means the device is in bootloader. We may do some steps to get it back.

1. Send JA command to switch to app mode. The raw command should be 0x55, 0x55, 0x4a, 0x41, 0x00, 0xf5, 0x9d

2. Upgrade firmware with command line.

Steps to upgrade OpenRTK330L_GNSS_RTK_INS_v23.05.bin

• Power off and on your device.
• Open python driver with specified parameters. Webserver_Win32_2.5.0.exe -c {the actual COM port} --cli. Wait for the device connected.
• Use command upgrade {the firmware path}
• Wait for the upgrade progress finished.

Thanks I got these:

The orange/green LED now slowly flash like it did before. But I cannot connect the Python. After I unplug the power and plug in again, no lights come on, not even the rapidly flashing green LED. What do I do?

The orange/green LED now started to flash after power cycle like it did before, but still Python driver does not connect:

OK, now it works after I remove the "-b 115200 "

Do I need to apply the calibration data since I erased everything using ST-LINK?
I went to https://developers.aceinna.com/devices/owned/2075000294 clicked "DOWNLOAD" under "Calibration Data" but got
"There is some error while generate download link. " Can you fix it? Also please let me know the instruction to apply the downloaded calibration data.

Hello,
same issue here, after failed online update, green LED keeps fast flashing. Only Bootloader is flashable via ST-Link.
But no connection via python driver. With all options / baud rates etc.
RTK GNSS INS App does not flash because of Memory bigger than flash memory...
The demo App loads via ST-link but still no connection via USB python.

Can you help me out?

Thanks

Any one found a solution for device not booting and green light flashing please ?

How to send a ```
JA commande please ?

@isat-engineerYou can try to use UartAssist.exe to send JA CMD
