When I use matlab R2019a to parse CAN blf Data,

Code: blfread("myfile.blf", "Database", candbc)

error: matrix dim must be same

When I use Matlab R2019b to parse CAN blf Data:

Code: blfread("myfile.blf", "Database", candbc)

There is no error, But I can't parse CANFD channel Data, the details is:

channel 1: “CAN”， [m*n]

channel 2: “CAN”，[m*n]

channel 3: "CANFD", []

there is no data in channel 3, but I use CANoe to parse the same blf file, there is many MSG data in channel 3.

Why? and how to solve this problem?

Hello,

I meet the same problem. blfread may not support CAN FD frame.

Have you solved the problem?

Hi Steve,

I too faced similar issue. Upgrading to version R2020b solved the issue, it should be working for R2020b and beyond.
