[oyster]

hi all， can you please help me to analyze such issues：

1、goto sleep ok；

2、can be waked up by 0x400 to 0x4ff；

3、but after sleep，if try to wake up by other id （not 400~4ff），cant be wakedup（it's ok），then try to wake up by 400~4ff， cant be wakedup forever。。。

many thanks ！！！

wake up frame cycle is 100ms，send count is -1（forever）；

if there is other frame（not set id）coming， then device will not be waked up forever， need power off to recovery

Hi,

Could you please be more specific about the test you are performing? Duration of sleep-wakeup cycle, sleep request steps, what kind of wakeup is configured, wakeup message specification, etc.

For TJA1145 with the dedicated wakeup frame, the internal decoder will be activated when TJA1145 receive the first CAN message in sleep. Hence, two frames should be sent at once, the second frame must meet the wake-up requirements, and then TJA1145 will wake up. As the decoder is designed for low consumption, if there is only one frame message, TJA1145 will stay in sleep mode.

Please keep the interval between two frames within tto(silence):

BR, Tomas
