CCS/UNIFLASH: UNIFLASH got an error "ERR_CONNECTION_REFUSED" when loading the image.

Hello,

What is the exact device that you are using with UniFlash? And with what connection type?

Thanks

ki

I am flashing IWR6843ISK via MMWAVEICBOOST USB connection (/dev/ttyACM0 in Ubuntu), but actually the problem occurred before accessing the device, since I got the same repro with and without the device connected. (Even w/o the device, UNIFLASH should display some error message in console subwindow, but nothing was displayed until the problem occurred) 

I guess that UNIFLASH internally launches some nodejs server and connects via WebSocket, but for some GPU-related reason, it seems to fail to create nodejs server instance and got the ERR_CONNECTION_REFUSED. Not sure what caused this problem.

Could you point how to collected related logs for debugging/info?

Thanks

It is odd that it is just that one machine while the other near identical environment is fine. Did you try uninstalling and the re-installing UniFlash? 

Also try the command line option:

http://software-dl.ti.com/ccs/esd/uniflash/docs/v5_0/quick_start_guide/uniflash_quick_start_guide.html#standalone-command-line-tool

And also the cloud based version:

https://dev.ti.com/uniflash

See if either of them work on the machine with the issue.

Thanks

None of them are working.

1. Cloud - DSLITE seems launched, but nothing occurred and exited

Updated ~/TICloudAgent/ticloudagent.sh to enable logging

export TI_DS_ENABLE_LOGGING=1
export TI_DS_LOGGING_OUTPUT=/tmp/ticld.log
echo "---$0 ARGS--- $1 $2 $3" > /tmp/ticld_args.log

Then, the collected log is

/tmp/ticld_args.log

You will need to pass in the COM port to be used. Otherwise it will always default to COM1.

try:

> sudo ./dslite.sh -c ~/ti/IWR6843.ccxml -s "COMPort=/dev/ttyACM0" ~/ti/pplcount_lab_xwr68xx.bin

Did you also try a complete reinstall of UniFlash?

I have uninstalled and reinstalled UNIFLASH for both GUI and Cloud versions, but both failed the same way.

The command line option with -s can connect to the IWR6843ISK board, but still failed due to invalid file order number (?) error.

Here is the executed command and the resulting log.

sudo /opt/ti/uniflash_5.0.0/uniflash/public/file_package_creator/templates/linux/dslite.sh --mode flash -c ~/ti/IWR6843.ccxml -s "COMPort=/dev/ttyACM0" -e -v -f ~/ti/mmwave_industrial_toolbox_4_0_1/labs/people_counting/68xx_people_counting/prebuilt_binaries/pplcount_lab_xwr68xx.bin

Thanks so much.

After adding ",1" and removing "-v", it worked very well. Although GUI/Cloud versions don't work, but I prefer the command line to flash. BTW, I got another error, "Unsupported GTI Function", after the successful flashing. Should I ignore the error?

Here is the command I executed for FYI.

sudo /opt/ti/uniflash_5.0.0/uniflash/public/file_package_creator/templates/linux/dslite.sh --mode flash -c ~/ti/IWR6843.ccxml -s "COMPort=/dev/ttyACM0" -e -f ~/ti/pplcount_lab_xwr68xx.bin,1

Thanks for another suggestion.

I am very happy with command-line option to flash the device. Thanks for all your help and have a great day!
