Hello!
based on the wireless-uart demo project, I want to use PC4(CAN_RX) to wakeup KW36 from DeepStop (VLLS2), I used the PWR_ChangeDeepSleepMode(5) and it looks that KW36 was waked up when I send can message. But the issue is the wakeup response time is too long, it's about 1.1 second. The picture below shows my messaurement result.
(1)The yellow color wave is PC4(CAN_RX) of KW36
(2)The Blue color wave is Reset pin of KW36
(3)The purple wave is PB1 pin of KW36, I set PB1 high in the function hardware_init(), that is the first function in the program.
(4) by the way, the reset status register RCM_SRS0=0x20, it means bit WDOG set, it looks watchdog triggers reset when can message wakeup KW36, but I never used watchdog in my code.
So plz help me to check :
1. the response time is the right? it is really so long? any document descrip it?
2. why WDOG bit set? it looks it should not happen
Hi,
既然它说复位信号是看门狗给的，那么你不给can信号，看看它还会不会看门狗复位。如果进了vlls2，看门狗应该是直接没用的。所以进没进vlls2还得打个问号
Have a great day,
TIC
