Linux/TDA2PXEVM: early boot late attach failed on TDA2PX

user5312037

Part Number: TDA2PXEVM

Tool/software: Linux

Hello:

Following the document vision_sdk/docs/Linux/VisionSDK_Linux_UserGuide.pdf, we are succeed to bring up the TDA2PXEVM board,

when we try to verify the early boot and late attach, the board will hung up.

the console output:

Hi,

Early boot and late-attach with Vision-SDK isn't supported on TDA2px (only works on tda2xx, tda2ex and tda2ex-17x17). This is due to dependencies in configuring ISS.

You can get more information on where the kernel initialization fails by increasing the log-level in the kernel device-tree (as part of the chosen argument).

Regards
Shravan

Hi:

Early boot and late attach is the key requirement for ADAS please have look at https://e2e.ti.com/support/arm/automotive_processors/f/1021/t/684708?tisearch=e2e-sitesearch&keymatch=%20user:354540

now, we'are using TDA2PX for our ADAS product, is there workaround to let it work?(we use ISP, maybe not use ISS)

Thanks

TI__Genius 14650 points

Hi,

You can increase the log-level in the kernel-DTB file to figure out where the kernel initialization fails (refer previous post on updating chosen node of DTB).

While building Vision-SDK, set ISS_INCLUDE=no in the file apps/configs/tda2px_evm_linux_all/cfg.mk, this should allow for early-booting of IPU and DSP firmware. We don't support early-boot for VSDK on TDA2Px, thus this configuration hasn't been tested.

Hi:
Thanks, try it.
Did you have plan to support it?

Hi,

We don't any immediate plans to support it.

Hi:
Bad news .......
Vision SDK is not support , so it only limited on sdk level, from technical point, it should be ok, my understanding is right?
BTW, I'm new to kernel device tree and there are such dts file nested, please give a detailed instruction to increase the kernel log.
Thanks

TI__Genius 14650 points

Hi,

Yes, early-boot is supported for TDA2px but VSDK doesn't.
Ensure you've applied the patches for early-boot on kernel. Once this is done, refer to dra7-evm-infoadas.dts, and add the chosen node entry to the dra76-evm-infoadas.dtb. Similarly ensure late-attach, disable-complete and disable_prcm entries are updated for dra76-evm-infoadas.dtb.

Hi:

please have look at the trace, already disable ISS

Hi,

Can you send the kernel-device-tree being used (both the dts and dtb file)? Also what is the targeted application? What sensor is being used?

Hi,

Please add below entries to your dts file.

DISABLE_COMPLETE(qspi);

&ipu2 {

timers= <&timer9> , <&timer11>;

};

Please do try the above changes, if the above configuration also fails, build the VSDK firmware with ISS_INCLUDE=yes and try, if no sensor initialisation is being done, it may succeed.

Regards

Shravan

Hi,

What is the intended project / end product?
I've reproduced the setup at our end, and the current Vision-SDK is not able to support Early-boot + Late-attach from Vision-SDK (even after ISS_ENABLE=no).

Regards
Shravan

0 user5312037 over 5 years ago in reply to Shravan Karthik

Genius 4320 points

Hello Shravan:

Our product will use the TDA2PHG, and now we'are using the TDA2Px to verify the early boot and late attach.

As your mentioned above that to modify the dts file, we try it according your suggestion, but still failed, and post the related log and dts files.

Hi,

I'm working to root-cause the issue observed. Please give me a few days, will post an update on this thread.

Hi,

Please apply this patch on Kernel and rebuild.

We've validated it works on TDA2PX with ISS_INCLUDE=yes with early-boot late-attach.
