MMWAVEICBOOST: Flashing .bin file

MMWAVEICBOOST: Cannot Flash MMWAVEICBOOST

Danilo A.
Mastermind 28700 points
Part Number: MMWAVEICBOOST
Other Parts Discussed in Thread: AWR6843ISK, UNIFLASH, AWR6843, IWR6843

Hi Team,

We would like to ask your help regarding yur customer's inquiry below.

I am currently working with the AWR6843ISK + MMWAVEICBOOST + DCA1000. I got The AWR6843ISK working with some example demos and your web interface.

Afterward I wanted to connect it to the MMWAVEICBOOST board but I cannot flash anything. After going through lots of documentation and online forums I could not help myself.

I do see the COM ports of the board within the device manager but Winflash does not flash it.

I followed these guidelines:

https://dev.ti.com/tirex4-desktop/content/mmwave_industrial_toolbox_4_11_0/docs/software_guides/using_uniflash_with_mmwave.html

when following this guide:

https://training.ti.com/hardware-setup-mmwaveicboost-and-antenna-module?context=1128486-1139154-1147568

Both COM ports are visible in the device manager

However, there is no success with flashing the AWR6843ISK through the MMWAVEICBOOST board.

I also tried to flash and debug it with CCS, which goes along with multiple errors from building projects, where it says „device unsupported“ till connections where the debugger seems to connect to the controller but is aborted before going into the main routine.

Is it correct, that the LEDs close to SOP jumpers have different intesities?

When measuring the voltage I observe:

5V In -> 5.19 V

NEVR -> 3.27 V

3V3 -> 3.27 V

SOPx -> 1.8 V When the jumper is closed

NRST -> 1.71 V

(All measured before the resistors)

The following page mentions when NRST glows the device is in reset state.

It is continuously glowing until NRST button is pressed.

What ist he difference compared to DS1? Since they behave equally

Danilo

    Hi Danilo.

    I would first make sure that the pins on the AWR and ICBoost are set properly for flashing mode before flashing with uniflash.  I would also make sure that the user is not connected to the GUI while trying to flash as the COM port will still be occupied by the GUI.

    Hope this helps,

    Hi Santosh,

    Thank you for your response. Here is the feedback of our customer

    Some More Information…..

    The AWR6843 is still connected to the MMWAVEICBOOST board.

    We measured the voltage level at C21 to obtain the V_IOIN pin voltage and measured 3.3V.

    Regarding the following information:

    We concluded to have 3.3V logic.

    The SOP0 jumper at the MMWAVEICBOOST is closed and S1.3 is OFF.

    Subsequently we measured the voltage level at R209 to get the voltage level of SOP pin an measured 1.71 Volts

    Compared to your design, is that compliant?

    With expected to measure something around 2.7V.

    Regards,

    Danilo

    Hello,

    Can you please confirm how you are setting the SOP jumpers on the ICBOOST? Did you set the jumpers on the SOP pins to flashing mode?

    Regards,

    Hi Adrian,

    Here is the response of our customer.

    The jumpers on the MMWAVEICBOOST are set to flashing mode (101), with DIP switches for Standalone Mode and DIP Switches from the EVM are all sett OFF except pin 5.

    Please also see the descriptions and pictures of my previous emails.

    Hi Adrian,

    I just received this email from our customer.

    I also discovered that the SOP state seems not always to be correct within the chips memory.
    Following this posts e2e.ti.com/.../iwr6843isk-cannot-connect-to-com-port
    Hower everything seems to be unstable since also the debugger does not work in a proper way

    Hello,

    Can you ask the customer to manually toggle NRST after powering up and see if the SOP state is detected correctly?

    Also, please confirm if the customer is able to flash the board without the ICBOOST. Is there a reason why the customer is using the ICBOOST to flash? The board can be flashed without using the ICBOOST.

    Regards,

    Adrian

    Hi Adrian,

    According to our customer,

    Is there a possibility to see whether the SOP state is correctly set or not apart from connecting to the controller and look into the memory?

    I am asking since the connection does not always work and sometimes I just don’t get a connection.

    As mentioned before, the SOP state does not always seem to be set correctly and manual resetting is only an option if the connection to the controller works to notice when the SOP state is set correctly.

    The EVM can be flashed without the MMWAVEICBOOST.

    But it should also be possible with it.

    I am just trying to flash it via the MMWAVEICBOOST as first step.

    Later on we would like to write our own code and debug it.

    Regards,

    Danilo

    Hello Danilo,

    Sorry for the delay, I have been out this week with Covid. I will be returning to the office on Tuesday of next week. I have never actually tried to flash the sensor using ICBOOST before, usually I just flash in standalone mode, so please give me until Tuesday or Wednesday of next week to try this out on my end so I can provide you with the exact steps. If the issue persists after we try that, then there is likely a hardware problem with the ICBOOST which may mean that the board is damaged somehow and needs to be replaced.

    Regards,

    Adrian

    Hi Adrian,

    I understand. We will wait for your update when you are back in the office next week. Get well soon.

    Hello,

    I was able to flash with no issues using the setup below.

    1. USB connected to J11 on ICBOOST

    2. Jumpers P6 and P4 closed on ICBOOST

    3. Switch settings as shown on ICBOOST and ISK

    - open uniflash

    - select serial > IWR6843

    - set COM port to UART port number

    - flash device

    If the above does not work then there is likely a hardware issue with one of your boards. 

    Regards,

    Adrian

    Hi Adrian,

    I just received this update from our customer.

    I tried the steps as described below several times without success.
    We do have the hardware twice (purchased at the same time) and my colleague has problems as well.
    I forwarded the answer to him and will inform you later.

    Can you please confirm if the board is defective based on your assessment so that we could process the replacement?

    Regards,

    Danilo

    Hi Adrian,

    I received another update from our customer,

    I got the confirmation from my colleague, that your set up also works for him.
    Do you have any ideas whether the EVM or the ICBOOST may be damaged?

    Regards,

    Danilo

    Hello,

    Can you please ask the customer to swap his ICBOOST board with his colleague and test? If the issue follows the ICBOOST then we know this an issue with the ICBOOST and not the radar EVM.

    Hi Adrian,

    According to our customer,

    I received the hardware from my colleague and tried to flash his hardware.
    It works very sporadically for me, most of the time I see the error as shown in picture 1.



    However, sometimes when the tool is able to erase the flash as shown in picture 2 it works.
    But the latter case is very rare.
    Do you have any idea what causes the problem?

    I tried it on two different PCs running (Windows 10 and 11)
    Both show the same behaviour

    Regards,

    Danilo

    Hello Danilo,

    Just so I understand correctly, the customer only swapped the ICBOOST board with his colleague and he kept his original AWR6843ISK board, is that correct? In this case it seems like there is some issue with the UART connection from the on the AWR6843ISK board to the ICBOOST board, I would recommend to submit a customer support ticket to return the AWR6843ISK board.

    https://ticsc.service-now.com/csm

    If the issue occurs when BOTH boards are swapped with his colleague, then it seems like this is a PC related issue. In this case, I don't think there is much we can do beyond try to reinstall the UNIFLASH program.

    Regards,

    Adrian

    Hi Adrian,

    I just received this email from our customer.

    please excuse the delayed response.

    I tried to swop both ISK and ICBOOST.

    Sometimes it works but most of the time it does not without changing anything at the hardware….

    Can it be that the SOP state is not detected correctly?

    Regards,

    Danilo
