IWR6843ISK: SBL: SBL_imageLoader() Fail to Downloads the Application Metaimage from FLASH to respective RAMs

Hi,

Whats the SDK version you are using.

Thanks

Yogesh

Hi TI Expert,

SDK version is 03_02_00_04, and IWR6843 is ES1.0

BRs

Hi TI Expert,

Is there any comment for us?

BRs

Hi,

We are not able to reproduce the issue. Is there any changes that you have made to the SBL code.

Thanks

Yogesh

Hi TI Expert,

We just to add log for checking the fail reason, and does not change any other code.

BRs

Hello,

Could you please format the SFlash using Uniflash first then flash the SBL and application metaimage again and see if you get this error?

Thanks

Hi TI Expert,

> Could you please format the SFlash using Uniflash first then flash the SBL and application metaimage again and see if you get this error?

==> Yes, I still meet this error.

Could you please tell which version SDK and SBL could work at IMR6843 ES1.0?

BRs

Hi,

Is this resolved or are are you still facing any issue.

Thanks

Yogesh

Hi TI Expert,

After using SDK 3.2.1.2, we test still fail.

We use domo image of SDK 3.2.1.2 and SBL of sdk_03_03_00_03: SBL update image success, but IWR6843 could not work(mmWave_Demo_Visualizer could detects IWR6843's port, but could not connect IWR6843)

could you please tell how to check IWR6843's status. and is there any way to flash IWR6843 back to demo image without SBL.

BRs

Hi,

Please use SBL and MMWAVE Demo both from SDK 3.2.1.2 for ES1.0. 

Could you please share the UART log if possible.

Thanks

Yogesh

Hi TI Expert,

I flase SBL(just add log) and Demo(as factory default backup image) both from SDK 3.2.1.2. test fail, and log as below,

----------------------------------------------------- fail log begin -------------------------------------------

Hi,

Could you please answer couple of question to narrow down the issue:

1) Are you using TI MMWAVEICBOOST + IWR6843ISK or is this your own custom board.

2) If this is TI MMWAVEICBOOST + IWR6843ISK:

    Did you try to send the same file using xmodem protocol to see if you are able to update.

3) Did you try to connect to CCS once the log stopped. If yes, where was the Program Counter, could you please share some details.

Thanks

Yogesh

HI TI Expert,

> 1) Are you using TI MMWAVEICBOOST + IWR6843ISK or is this your own custom board.

==> I use TI MMWAVEICBOOST + IWR6843ISK ES1.0

> 2) If this is TI MMWAVEICBOOST + IWR6843ISK:

>    Did you try to send the same file using xmodem protocol to see if you are able to update.

==> Yes, I have try to send the same demo image file using xmodem protocol, it send to device success but fail to download the image to RAM.

> 3) Did you try to connect to CCS once the log stopped. If yes, where was the Program Counter, could you please share some details.

==> Yes, I try to connnect CCS with IWR6843ISK device, and debug soming. Is this will cause SBL issue?  This IWR6843ISK has been flash with new SBL image and demo image using UniFlash. Seems "connect to CCS once once" could not cause this SBL issue. 

BRs

Hi BRs,

Sorry, I could not understand the answer to the item 3.  Are you saying that after connecting to CCS. you are no longer able to re-produce the SBL issue?

Thanks

Yogesh

Hi TI Expert,

I have connect IWR6843ISK with CCS and test for CANFD function.

For SBL function, I use Tera Term(not CCS) to test. and the log come from Tera Term.

BRs

Hi BRs,

Just connect the CCS after the SBL fails. And pause the r4 processor. Once you have paused the processor  "Load Symbols"  and select file:

~\packages\ti\utils\sbl\xwr68xx_sbl_mss.xer4f

Refer Image:

Thanks

Yogesh

Hi TI Expert,

How to pause the r4 processor after connect the CCS?

And "Load Symbols" is inactive state, so I could not click "Load Symbols".

BRs

Hi BRs,

Could you please share your CCS screen shot.

Thanks

Yogesh

Hi TI Expert,

Connect to CCS after SBL fail, CCS fail to connect IWR6843 because of "Halt On Reset"

CCS screen shot as below,

Hi BRs,

Was CCS open when you were doing SBL test. If yes, could you please try and close the CCS and run the SBL. Also connect CCS only after SBL has failed.

Thanks

Yogesh

Hi TI Expert,

> Was CCS open when you were doing SBL test.

==> NO. CCS be closed when test SBL.   I test as the following steps

1. Use Tera Term to test SBL, SBL fails.

2. close Tera Term

3. Open CCS 

Hi BRs,

Seems something has gone wrong with the IWR6843 device. Do you have another device to try?

I guess you are able to run demo image w/o SBL.

Thanks

Yogesh

Hi TI Expert,

> I guess you are able to run demo image w/o SBL.

==> No. I flash demo image without SBL into this device, the device still does not works.

> Do you have another device to try?

==> I have anoter device, but can't do SBL test on it before fix this SBL issue.

BRs

Hi BRs,

If the mmw demo image is not working by flashing directly, it will not work with SBL. 

Am I missing anything?

Thanks

Yogesh

Hi TI Expert,

The demo image works ok on this device before test SBL. But the demo image does not work on this device after test SBL. I'm no idea if there any issue. 

Do you have ever test SBL OK on IWR6843 ES1.0?

BRs

Hi Brs,

Yes, we have tested SBL on ES1.0 and it works. Try Formatting the flash from "Settings and Utilities" in UniFlash.

Thanks

Yogesh

Hi TI Expert,

> Try Formatting the flash from "Settings and Utilities" in UniFlash.

==> 1) Formatting the flash of IWR6843 es1.0;  2) Flash demo image of SDK3204 into IWR6843 es1.0, IWR6843 es1.0 could not work; 3) Flash demo image of SDK3212 into IWR6843 es1.0, IWR6843 es1.0 could not work too.

But this device works ok before testing SBL. 

BRs

Hi,

Not sure how SBL failure will cause issue with subsequent flashing of the OOB demo. Seems something odd with this device.

Thanks
