Part Number: AWR1642

Tool/software: TI-RTOS

I use the CAN-bus to transmit data of mmwave.

First, open the CAN-bus on computer and send CLI command to AWR1642.

AWR1642 can successfully transmit data.

After the computer suddenly close the CAN-bus, the computer restarts CAN-bus.

It can't receive any data from AWR1642. And computer still can send CLI command to AWR1642. It will receive Done or Error -1.

Is there any method avoid CAN-bus crash in this case?

Hello Jui Yang,

Do you see any error on the device side in the CCS console ? What application are you using on the device side ?

Hello Raghu,

There aren't any error or message in CCS console with CCSdebug.
And we also can load CFG to AWR1642, it's OK.
We use PCAN-USB(PEAK).

After we reproduce the bug, we notice CAN-FD doesn't crash every time.
And if we reduce frequency from 10Hz to 5Hz.
The probability of crash has decreased.

Hello Jui Yang,

What is this frequency you are talking about (10Hz to 5 Hz)?

Hello Raghu,

Change frameCfg-framePeriodicity from 100 to 200.
