FlexRay not starting after changing the Protocol settings

mexx1860 — Mon, 08 Jul 2013 08:37:29 GMT

Hi,

i'm actually trying to get a working FlexRay Bus with the 2 Node Starter Kit of EVB9S12XF512E.

The sample code coming with the Boards works fine but as soon as I change the Protocol settings in the Fr_UNIFIED_cfg.c the Nodes wont coldstart anymore.

The old (working) settings are:

const Fr_low_level_config_type Fr_low_level_cfg_set_00 =

{

10, // G_COLD_START_ATTEMPTS

3, // GD_ACTION_POINT_OFFSET

83, // GD_CAS_RX_LOW_MAX

0, // GD_DYNAMIC_SLOT_IDLE_PHASE

40, // GD_MINISLOT

3, // GD_MINI_SLOT_ACTION_POINT_OFFSET

50, // GD_STATIC_SLOT

13, // GD_SYMBOL_WINDOW

11, // GD_TSS_TRANSMITTER

59, // GD_WAKEUP_SYMBOL_RX_IDLE

50, // GD_WAKEUP_SYMBOL_RX_LOW

301, // GD_WAKEUP_SYMBOL_RX_WINDOW

180, // GD_WAKEUP_SYMBOL_TX_IDLE

60, // GD_WAKEUP_SYMBOL_TX_LOW

2, // G_LISTEN_NOISE

5000, // G_MACRO_PER_CYCLE

10, // G_MAX_WITHOUT_CLOCK_CORRECTION_PASSIVE

14, // G_MAX_WITHOUT_CLOCK_CORRECTION_FATAL

22, // G_NUMBER_OF_MINISLOTS

60, // G_NUMBER_OF_STATIC_SLOTS

4920, // G_OFFSET_CORRECTION_START

16, // G_PAYLOAD_LENGTH_STATIC

5, // G_SYNC_NODE_MAX

2, // G_NETWORK_MANAGEMENT_VECTOR_LENGTH

FALSE, // G_ALLOW_HALT_DUE_TO_CLOCK

20, // G_ALLOW_PASSIVE_TO_ACTIVE

FR_CHANNEL_AB, // P_CHANNELS

300, // PD_ACCEPTED_STARTUP_RANGE

56, // P_DECODING_CORRECTION

601, // PD_MAX_DRIFT

0, // P_EXTERN_RATE_CORRECTION

1, // P_KEY_SLOT_ID

TRUE, // P_KEY_SLOT_USED_FOR_STARTUP

TRUE, // P_KEY_SLOT_USED_FOR_SYNC

242, // P_KEY_SLOT_HEADER_CRC

21, // P_LATEST_TX

5, // P_MACRO_INITIAL_OFFSET_A

5, // P_MACRO_INITIAL_OFFSET_B

23, // P_MICRO_INITIAL_OFFSET_A

23, // P_MICRO_INITIAL_OFFSET_B

200000, // P_MICRO_PER_CYCLE

1201, // P_OFFSET_CORRECTION_OUT

600, // P_RATE_CORRECTION_OUT

FALSE, // P_SINGLE_SLOT_ENABLED

FR_CHANNEL_A, // P_WAKEUP_CHANNEL

16, // P_WAKEUP_PATTERN

40, // P_MICRO_PER_MACRO_NOM

8 // P_PAYLOAD_LENGTH_DYN_MAX

};

And the ones I wan't the nodes to start with are:

const Fr_low_level_config_type Fr_low_level_cfg_set_00 =

{

8, // G_COLD_START_ATTEMPTS

2, // GD_ACTION_POINT_OFFSET

79, // GD_CAS_RX_LOW_MAX

50, // GD_WAKEUP_SYMBOL_RX_LOW

301, // GD_WAKEUP_SYMBOL_RX_WINDOW

121, // P_RATE_CORRECTION_OUT

FR_CHANNEL_A, // P_WAKEUP_CHANNEL

33, // P_WAKEUP_PATTERN

40, // P_MICRO_PER_MACRO_NOM

8 // P_PAYLOAD_LENGTH_DYN_MAX

};

Do I need to take care of something else when changing the settings?

I would apreciate any help.

I think it has something to do with the different Payload lengths of the static segment.

But I haven't figured out yet which settings I need to change in the MB config.

If you change G_PAYLOAD_LENGTH_STATIC from 16 to 8 you also need change payload lenght to 8 in Fr_transmit_buffer_config_type Fr_tx_buffer_slot_XX_cfg structure. Also you need generate new header CRC in this structures.

Hi Milan,

thank you for your answer but I have changed the CRC and it's still not working. I think it has something to do with these 4 settings:

G_MACRO_PER_CYCLE

GD_STATIC_SLOT

G_NUMBER_OF_STATIC_SLOTS

G_OFFSET_CORRECTION_START

If I change them I will get stuck in the FR_init function. The Fr_start_communication API is successfull but afterwards I am stuck in the next while loop waiting to get away from FR_POCSTATE_NORMAL_ACTIVE but this never happens.

Hi Milan,

Can you help me, which program is seen on your screenshot?

Thanks
