Hello,
I try to receive rtr Messages over the DCAN1 at the TMS570LS0432.
To receive the Messages I configured a message box with following configurations:
MsgVal = 1 , Xtd = 0, Dir = 1, UMask = 1, TxIE = 0, RxIE = 1, RmtEn = 0, TxRqst = 0, EoB = 1, DLC = 0, MXtd = 1, MDir = 1, Msk[28:0] = 0
At the reception of a message without rtr I get the message box from the DCAN INT register and I can red the data from the message box.
After the transmission of a rtr message I get an Interrupt at the microcontroller.
In the interrupt I read the DCAN INT register but I only get the information that the DCAN ES register has changed and not the message box.
In the DCAN ES register is only the bit RxOK set.
Why isn't the messagebox in the DCAN INT register set after a rtr reception.
Best reguards
Tobias
