About CAN Wakeup Pulse in MC33742

[vinman0261]

Folks,

Using MC33742 (SBC - CAN Transceiver - 28 pin IC) in one of our project.

Initialized the Transceiver in Normal mode. After 100 milliseconds of Power up, CAN TX (Pin# - 2) is getting reset.

Due to this reset pulse, we couldn't able to transmit data via CAN bus. Attached the evidence for the same.

Can anyone tell me how to resolve this issue.

Thanks

It is being solved internally (Case 00151731).

Hi Tomas,

i'm facing the same issue :smileysad: The SPI init sequence is the one suggested in the datasheet (DEBUG MODES WITH SOFTWARE WATCHDOG DISABLED THOUGH SPI) and i'm sending via SPI the commands  {0xB5, 0x10, 0x15, 0x5F}.

What i'm missing? How did you manage to solve the problem?

Thanks,

Andrea
