Hello everyone,
I recently purchased the IWR6843ISK-ODS mmWave sensor evaluation kit, along with the carrier card platform mmWaveIcboost. I am excited to explore its capabilities and start working on my project. However, I have encountered a problem while trying to load firmware onto the IWR6843ISK using Uniflash.
When attempting to use Uniflash, I encountered the following error message:
"[ERROR] Cortex_R4_0: Serial port /dev/ttyACM0 specified does not exist, is already open, or permission is denied!!"
This error has left me wondering whether the device is broken or if there is a misconfiguration issue. I'm not sure if the error message indicates a problem with the hardware, such as a faulty serial port or a misconfigured connection, or if it is related to software settings. For every try I pressed the NRST button and even tried to disconnect the board entirely from my PC and power supply, but with no results
I have double-checked the physical connections between the IWR6843ISK and the carrier card, ensuring they are properly connected. Additionally, I have verified that the required drivers are installed on my computer. Despite these precautions, I am still unable to successfully load the firmware using Uniflash.
I'm reaching out to the community for any suggestions or insights that could help me diagnose and resolve this issue. Has anyone encountered a similar problem with Uniflash and the IWR6843ISK-ODS? If so, I would greatly appreciate any guidance on troubleshooting steps or potential solutions.
Here are a few specific questions that come to mind:
Could this error be caused by a misconfiguration in Uniflash or any other software settings? If so, what are the possible areas I should check and adjust?
Is there a way to verify if the IWR6843ISK-ODS device itself is functioning correctly? Are there any diagnostic tests or tools I can utilize to ensure its proper operation?
Are there any alternative methods or tools available for flashing firmware onto the IWR6843ISK-ODS that I can explore as a workaround?
I would be grateful for any advice or suggestions from those who have experience with the IWR6843ISK-ODS and Uniflash. Thank you in advance for your assistance!
Best regards,
Hi Luke,
thank you for your respone. I have followed the instructions meticulously. The mux-switches and SOPs are set correctly and I can tell you its correct as I steup a completely new computer, installed just the Clouod Agent and got it working with the online uniflash ONCE! Than, the next day, without changing any settings, it than would give me the same error again. I even tried to reinstall Windows again, but it wouldn't work anymore. Some odd behavior I found on Uniflash is, that the autodetected board is not the IWR6843(ISK-ODS), but the ICBOOST and every time I press start it just loops and does nothing so I have to select the board manually. And trying to connect the IWR board directly (without the ICBOOST) does not detect anything (after changing the mux-switches of course). Maybe this is something to look at? Attached I have the board with the switch states in flashing mode and the Uniflash main page.
Maybe you can help me troubleshoot some further.
Thanks in advance,
Constantin
Hi Luke,
tl;dr: IWR6843 standalone works flawless, with the ICBOOST attached it's not possible flash software.
ok, I've went through every step again to write them down:
IWR6843ISK-ODS standalone:
1. mux switches in flashing mode (Pic.1)
2. connect usb cable
2a. see if DSLite.exe runs in Task-Manager and kill it (from possible prior flashes)
3. open uniflash app / online (not both at one)
4. Choose IWR6843 (Chip) or IWR6843ISK (DevKit) manually
- both worked, online and offline version
- Uniflash did not autodetect anything
4. load xwr68xx_demo.bin
5. set COM port to enhanced port
6. press reset button
7. press "Load Image"
8: Console output message:
-->Erasing storage[SLFASH]
...
[SUCCESS] Program Load completed successfully.
9: Be Happy!
ICBOOOST attached:
1. mux switches in flashing mode (Pic.2)
2. connect usb cable, then power cable
2a. see if DSLite.exe runs in Task-Manager and kill it (from possible prior flashes)
3. open uniflash app / online (not both at one)
4. Choose IWR6843 (Chip) or IWR6843ISK (DevKit) manually
- neither worked, online and offline version
- Uniflash detected:
4. load xwr68xx_demo.bin
5. set COM port to Application/User UART
6. press reset button
- tried the NRST button on the ICBOOST, the reset on the IWR and both
7. press "Load Image"
8: Console output message:
"Set break signal"
(20 sec. of waiting. I tried monitoring the COM port meanwhile and seems to try to make a connection but fails in 2-3sec intervals. DOWN, UP, TIMEOUT,... see Annex I)

Some questions that I have in my mind:
- Is it possible to find out if the 60-Pin connector has a a detection issue?
- Is it possible to find if the ICBOOST is in flashing mode or not?
- There are many other knob and bridges on both sides of the board. Are these set correctly?
I am now working on more than just under two months figuring out the problem of that board. Is it possible to get a new one. I don't really have any more time to loose on this project.
