Can Not Register While Using MSCAN_KEA_DEVD Driver For Test

brightwang — Tue, 24 Jan 2017 07:24:29 GMT

I'm Using MSCAN_KEA_DEVD Driver For My Kineties EA Projects Upon TRKEA128 Board. While Testing Load Balance I Find Something Error With MCU Reg. When I Get A Bytestream With Data Field Full Of 00 / 0XFF The Receving Thread Will Be Stuck In. No In-coming Message Will Changes The Reg But A Working Counter Here . It Is To Say I Cannot Read Any Update In Reg But Counter Is Still Working:

MSCAN_CANCTL0 0x98 0x40024000
MSCAN_CANCTL1 0xc4 0x40024001
MSCAN_CANBTR0 0x01 0x40024002
MSCAN_CANBTR1 0xdc 0x40024003
MSCAN_CANRFLG 0x00 0x40024004
MSCAN_CANRIER 0xff 0x40024005
MSCAN_CANTFLG 0x07 0x40024006
MSCAN_CANTIER 0x00 0x40024007
MSCAN_CANTARQ 0x00 0x40024008
MSCAN_CANTAAK 0x00 0x40024009
MSCAN_CANTBSEL 0x02 0x4002400a
MSCAN_CANIDAC 0x00 0x4002400b
MSCAN_CANMISC 0x00 0x4002400d
MSCAN_CANRXERR 0x1f 0x4002400e
MSCAN_CANTXERR 0x00 0x4002400f

Does Anyone Has Same Problem?

Does Anyone Here Meet With The Same Problems With RX Register When Getting 00 00 00 00 00 00 00 00 Data Field?

I do a test with TRK-KEA128 board with MSCAN driver and could get CAN data frame: 00 00 00 00 00 00 00 00 with <Demo_Receive_DataFrame>.

In <main.c> file using below code:

TEST_CASE_FUNC(Demo_Receive_DataFrame);

Please check below test result:

The MSCAN module registers value below:

Wish it helps.

Have a great day,
Ma Hui
