AWR2243: The AppImage form SDK3.7 and SDK3.8 can not running in Cascade Radar with AWR2243.

Hi,

Radar-SDK or Vision-SDK currently doesn't support AWR2243 at the software level.

You need to use different firmware image (xwr22xx_metaImage) from the mmWave DFP

http://software-dl.ti.com/ra-processors/esd/MMWAVE-DFP-2G/latest/index_FDS.html

And the firmware file type is changed from 4 (AWR1243) to 0 (AWR2243) which you need to change in the SDK code.

C:\PROCESSOR_SDK_VISION_03_08_00_00\ti_components\drivers\pdk_01_10_04_05\packages\ti\drv\vps\src\devices\radar_ar12xx\src\bspdrv_ar12xxFmwPriv.c: retVal = Bsp_ar12xxFmwSectionDwld(BSP_AR12XX_SECTIONTYPE_META_IMAGE   0); /* pass the value zero instead */

I tried to use mmWave Studio 2.1 to upgrade the firmware of 2243, but there was no XWR2243 option in it，I tried to click the Load button to download the firmware, and there is an error :

Did I do anything wrong? Or is there another way to update the  xwr22xx_metaImage?

Thanks a lot.

Hi,

You need to download different mmWave Studio which supports AWR2243 and select <DFP>\firmware\xwr22xx_metaImage.bin file to load.

I saw a mmWave studio -2g on TI's official website, but I could not download it. Could this support 2243?

2G meant for second generation of mmwave sensor : AWR2243.

You need to raise a request to get the download link, as download is available only on request.

I got the software today and updated the firmware of 2243 by running the script in mmwave_studio_03_00_00_07:

And I changed the code as you said and got the new appimage. I found that using 'gmak-s' and' gmak-s appimage' didn't change the content of AppImage , so I used the 'gmak-s clean' command and recompiled the entire SDK, but still couldn't get the radar to start.

I read the code and found that when the device was version 1.0, it didn't seem to go into the branch where the code had been modified.

Did I do any of the steps wrong?

Looking forward to your reply.

Thank you very much.

Hello,

Here is the code change I did to support AWR2243 with TDA vision-sdk application.

\ti_components\drivers\pdk_01_10_02_07\packages\ti\drv\vps\src\devices\radar_ar12xx\src

bspdrv_ar12xx.c:  ---->

    retVal = Bsp_ar12xxRadarDeviceOn();

    if ((retVal == BSP_SOK) && (downloadFirmware != 0U))
    {
        //gBspAr12xxObj.arDeviceRevision = Bsp_ar12xxGetDeviceRevision();
        gBspAr12xxObj.arDeviceRevision = 3U;
        /* Download the firmware and run it on the AR12XX device */
        retVal = Bsp_ar12xxFmwSpiDwld();

bspdrv_ar12xxFmwPriv.c ---->

#define AWR2243_DEV  1

/* ES3.0 Meta Image */
#ifdef AWR2243_DEV
#include <xwr22xx_metaImage.h> /* place the header file at the same location ti_components\radar\mmwave_dfp_01_02_00_00\firmware\ directory */
#else
#include <xwr12xx_metaImage.h>
#endif

Int32 Bsp_ar12xxFmwSpiDwld(void)
{
Int32 retVal = BSP_SOK;
UInt32 arDevRev = gBspAr12xxObj.arDeviceRevision;
if((arDevRev == 1U) || (arDevRev == 2U))
{
retVal = Bsp_ar12xxFmwSectionDwld(BSP_AR12XX_SECTIONTYPE_MSS_BUILD);

if (retVal == BSP_SOK)
{
retVal = Bsp_ar12xxFmwSectionDwld(BSP_AR12XX_SECTIONTYPE_BSS_BUILD);
}
if (retVal == BSP_SOK)
{
gBspAr12xxObj.radarInitCompleteFlag = 0U;
rlDeviceConfigureAckTimeout(0U);
retVal = Bsp_ar12xxFmwSectionDwld(BSP_AR12XX_SECTIONTYPE_CONFIG_INFO);
}
}
else if(arDevRev == 3U)
{
retVal = Bsp_ar12xxFmwSectionDwld(0);
}

I changed the code as you said:

but still got the same error:

Is there anything else that needs to be modified?

Thanks and Regards

Hi,

Could you check the file download status? Please try to do stepping with CCS to file the point where it returns non-zero value. I feel that after file download step somewhere else it hit the error.

Jitendra

Hi,

Unfortunately, I don't have this for debugging right now:

Could you please send me an SDK that can be used for 2243?

My email is guojun@microbrain.com.cn,

Thank you very much,

JG

Hi JG,

Radar SDK with AWR2243 is not yet available but you can build the debug image using the same procedure as v3.8 but with the above-mentioned code change.

Follow the user guide to load the image via CCS to TDA board.

Jitendra

Hi,

The code is now ready to run, but when running the radar_cascade_demo.m script it cannot display the range-azimutist heat map and the point cloud, only the range-doppler heat map and the range profile are output.

Is it because sdk3.7/3.8 support for 2243 is not perfect enough? Will an SDK for 2243 be available soon?

We will develop a new product based on 2243, so we are eager to know that.

Regards,

JG

Jitendra,

Shall we still need to keep the sectionType to BSP_AR12XX_SECTIONTYPE_META_IMAGE?

If we change it to 0, in Bsp_ar12xxFmwGetBuffers function, it will do nothing.

    else
    {
        /* For ES3.0 AR1243 */
        if (sectionType == (UInt32) BSP_AR12XX_SECTIONTYPE_META_IMAGE)
        {
            *pImgBuffer = (UInt8 *) metaImage;
            *imgLen     = sizeof (metaImage);
        }
        else
        {
            /* Any other file type currently not supported */
            retVal = BSP_EFAIL;
        }

Hi JG , Did you success fixing these problem ? Can you privide more info about this problem?

Hi,

For 2243, maybe we should wait for the new SDK.

Hi，

I have made processor sdk for radar v3.8 working with AWR2243 cascaded EVM. Pls find changes below and attached.

1. Download latest DFP for AWR2243 and install it.

   http://software-dl.ti.com/ra-processors/esd/MMWAVE-DFP-2G/latest/index_FDS.html

2. Copy xwr22xx_metaImage.h at C:\ti\mmwave_dfp_02_01_05_03\firmware to C:\PROCESSOR_SDK_RADAR_03_08\ti_components\radar\mmwave_dfp_01_02_00_00\firmware

3. Modified bspdrv_ar12xx.c and bspdrv_ar12xxFmwPriv.c at C:\PROCESSOR_SDK_RADAR_03_08\ti_components\drivers\pdk_01_10_04_05\packages\ti\drv\vps\src\devices\radar_ar12xx\src.

4. Modify code at C:\PROCESSOR_SDK_RADAR_03_08\vision_sdk\apps\src\rtos\radar\src\alg_plugins\alg_fxns\radardspcascademimo\radarDspCascadeMimo.c for MIMO demo.
