The statistics data of addrss value is show as follows:0x05E1A4C0; 0x05E1DB80; 0x05D19D40; 0x05E1A4C0; 0x05F1D140; 0x05C08410;

Similar aborts occur several times during the tests these days, the addresses captured are different, but all of these addresses are something a bit out of main R5F TCM regions. If this info helpful on analyzing the cause.

Thanks.

Hi, ti experts,

Additional information:

At the scene of the other cars, we also had a panic exception in A72. The CBASS_RC0_ERR register also had an similar address value（0x5e1d680）, as shown below.

See E2E Problem link for details:  https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1165329/tda4vm-tda4vm-a72-panic.

Please help identify the problem synchronously.

Hi,

Can you please provide more details abut the issue:
1) Is this a consistent issue? Are you seeing this every time on bootup?
2) If not consistent, how many times do you see the issue?
3) Also, what your firmware is doing when the issue occurs? Were you able to pinpoint the issue to a particular operation?

hi, ti experts,

1. not consistent issue. See the normal device, not have the rc0 error.

2. the issue happed not always,  ten vehicle test one day, mag happed 0~2 times,

3. fireware, we are trying now.

Hi Shuwan,

How easy it is to reproduce the issue? Were you able to reproduce this issue on the bench or this issue is always seen in the car? Can you please pinpoint exactly which operation is causing this issue?

Hi Fan,

As per mail communication:

Then, in order to isolate the issue, in C660, we change UDMA to memcpy. C660 does not abort, but MAIN R5F abort are captured.

Can you please share more details on the UDMA operations? What memories you are accessing and what channels you are using etc?

Regards,
Parth

hi, ti experts

1. The issue always happed in the vechicle test.  Most test are in the car.

Hi,

Can you try reproducing the issue on the bench and see if it is reproducible?

Also, please share the other details from the previous query.

Regards,
Parth
