AWR2944PEVM: HIL Demo

Part Number: AWR2944PEVM
Other Parts Discussed in Thread: AWR2944, AWR1443, UNIFLASH

Tool/software:

Hello.

I'm trying to bring up a demo on the AWR2944PEVM Evaluation board , this demo was sent to us by TI , it involves HIL playback ( of sensor ADC samples ) via the MPI CSI2 interface , 

the demo involved two boards AWR1443 as the transmitter and AWR2944 as the receiver , i'm only trying to bring up the AWR2944 part as we will be using our own playback source.

the demo folder included some prebuilt binaries for app images and sbl , and my understanding was that the uart_uniflash.py was to be used to flash these binaries on the board.

however after running the script , the flash_writer (1st step ) is completed , but the sbl binary is always stuck and returns this error after a while

"[ERROR] XMODEM send failed, no response OR incorrect response from EVM OR cancelled by user,
Power cycle EVM and run this script again !!!"

i tried many combinations of sbl/flash_writer binaries but always failing at step 2.  one flash_writer is able to write the sbl image but never completes step 2 due to the following error.

any help is appreciated. thanks in advance.

    Hello Mohammed,

    As mentioned to your team before, this is just a reference application for the AWR2944 Rev A.
    You are using the wrong silicon for this.

    You have to port the example from the AWR2944 -> AWR2E44P EVM

    The application provided to you was for only a skeleton structure for your application and reference, not for the final application.

    Hello Saswat,

    I have used this cfg file to flash the AWR2944 EVM default_sbl_csi.cfg but when I try to connect to DSS core CCS fails, when the default BL used CCS could connect on 2 cores but the app asserts these 2 files are used for the app awr2944_mmw_demo_dssDDM and awr2944_mmw_demo_mssDDM,

    could you advice which files should be used?

    Best Regards,

    Hello Hesham,

    This is only true for the REV A of the AWR2944 which is the ES 1.0
    Even if you use AWR2944 it will be the ES 2.0 variant, which is why it will not work. This I had mentioned in the mail and call to Denis as well. That is why this was a POC project only done long back.

    If you want to use the files present, you have to make similar changes in the latest SDK.
