I downloaded the "IMU Server Ready-to-Use (Windows)" on my Windows 10 computer. I also updated the firmware on the OpenIMU330BI to OpenIMUBI_1.1.1 using the STM32 St-Link Utility. When I run Server_win32_1.1.1, COM7, COM1, COM8, and COM9 are successfully checked, then I get the message "Cannot configure port", and the terminal window suddenly closes.

if you follow the link https://forum.aceinna.com/topic/75/update-openimu330bi-new-firmware and upload firmware , and then get the data package 55 55 7A 31 XX XX ... via uart interface, will support the python driver connection.

I changed USB ports twice, restarting the operating system each time. The ST-Link is directly connected to the USB hub without a USB hub, which it has been all along. Using the Target > Option Bytes utility in ST-Link v4.5.0, I set Pages 58-63 to have Write Protection as shown in Li YiFan's link above. The screen shot from the ST-LINK > Printf via SWO viewer utility in St-Link is shown below. It does to indicate the baud rate. How else can I check the baud rate and observe the hex displaying mode?

if at first the 6 pages not protected in above question, pls finished the uploading from Li YiFan's link above.

3. you mentioned " I also updated the firmware on the OpenIMU330BI to OpenIMUBI_1.1.1 using the STM32 St-Link Utility", pls give me youre SN number? mine SN is: 1927300538.

if you follow the link https://forum.aceinna.com/topic/75/update-openimu330bi-new-firmware and get

Hi Li,

I followed the link you provided: https://forum.aceinna.com/topic/75/update-openimu330bi-new-firmware

The webpage at the link provided above shows a set of screenshots for the ST-LINK program. I was not able to find the data package 55 55 7A 31 XX XX anywhere in that webpage. Can you verify that you sent me the correct link?

so pls refer to my comments above? and we can go on the discussion..

for serial tool get data and check FW version, pls refer to summary topic link of open-imu family:

Hi cek,

Here's a screenshot of the data from HTerm on COM14:

The last 6 Pages (58-63) are write protected when I first open the Target > Settings > Option Bytes window.

My Serial Number from the label on the OpenIMU330BI EVK is:
1927300441

Hi cek,

Here's another screenshot of the HTerm data with the data type set to Hex and the data scrolled back to the beginning. The first few bytes do indeed read 55 55 7A 31 as you can see.

then pls follow below topic_5 steps to upload the bin to your IMU330:
https://forum.aceinna.com/topic/93/top-topics-of-common-operations-with-openimu-products

reset the power, you should connect the ANS web.

Hi cek,

I installed the EEPROM bin file which you sent to me exactly according to the instructions under section 5 of the link above, starting at location 0x08000000, with a size of 0x30000. I set the 6 Option Bytes afterward and restarted the IMU board. I could not get the IMU to connect. I repeated the procedure again. I still cannot connect to the IMU with the OpenIMU Monitor. What should I do?

After establishing communication with the ST_LINK Utility, I tried to connect to each of the 5 COM ports using HTerm while the ST-LINK/V2 debugger LED is flashing alternately green and red. I could not get any data from the IMU over HTerm.

I also disconnected the IMU with the ST-LINK Utility and then again tried to connect to each of the 5 COM ports using HTerm while the ST-LINK/V2 debugger LED is constant red. I could not get any data from the IMU over HTerm.

Hi cek,

I performed the steps above exactly as listed. Here is a screenshot of the ST-LINK Utility after successfully uploading the bin file, locking the sectors, and restarting the IMU:

I immediately saw good data over HTerm on COM14:

However, I still cannot connect to the OpenIMU Monitor at developers.aceinna.com/devices/record-next

What next steps should I take?

Hi Li-YiFan,

I downloaded the IMU Server Ready-To-Use (Windows) using the Chrome browser and installed it as shown above. I still cannot connect to the IMU using ANS. After opening ANS, when I run Server_win32_1.1.1, a DOS console window opens briefly as shown here:

It gives the message as shown: "Cannot configure port, something went wrong. Original message: .."

How should I correct this problem?

Second, pls use the testing server.exe try again, if still not, pls send to us the Server_log file which in same file with server.exe
server_191123_with_log_8000.exe
thanks a lot.

Hello cek,

I downloaded the EEPROM bin file and ran the server file you sent me with the log. I cannot attach them here. How do I send these files to you?

Hi Li-YiFan,

Here is a screenshot of the Visual Studio Code terminal window after running server.py. It has the same output as Server_win32_1.1.1. The DOS command window disappears very quickly after running Server_win32_1.1.1, so the picture is blurry.

Here is a screenshot of the server log file:
