TDA4VM: (RTOS SDK) Incremental Update and Debug with TFTP

FredC_LT

Part Number: TDA4VM

Hi,

I want to do incremental updates on the R5/C66,C7 images by modifying the vision_apps code provided by the RTOS SDK.

Following these instructions, I'm able to rebuild the sdk and generate the linux and rtos images. However, the only provided method to actually update the cores is to reflash the SD card.

I'd like to be able to update the cores without having to remove the SD card from my device, as I do most of my development remotely (TDA4 at work, me at home). I do have remote access to the serial port of the device, so there's no issue interrupting u-boot after a reset.

Is there a guide to update the images from U-Boot by using the built images from "make linux_fs_install_sd" that would reside on a TFTP server?

Thank you,

Fred

Ok, an even easier way is to update the firmware files on the filesystem, and let remoteproc handle the rest.

Modify C7 code
cd ${PSDKR_PATH}/vision_apps
make vision_apps -j$(nproc)
scp ./out/J7/C71/FREERTOS/release/vx_app_rtos_linux_c7x_1.out root@<target_ip>:/lib/firmware/vision_apps_evm/vx_app_rtos_linux_c7x_1.out
ssh root@<target_ip> reboot

Please confirm that this method is safe and that I'm not missing any step.

P.S.: I also tried

echo stop > /sys/class/remoteproc/remoteproc3/state

echo start > /sys/class/remoteproc/remoteproc3/state

But it seems it's not supported for the C7x. I just had to reboot to make it work.

Hi, it is not.

Did I need to do something else than click "this resolved my issue"?

Yes usually that will do. I will now be closing this thread. Thank you.
