Recently, I meet a strange issue that when I set the S32DS3.5 optimization level to -O2
After set the optimization level to -O2, the CAN goes to bus-off status, but there is no bus-off event happen, so I wonder why setting the S32DS3.5 optimization level can cause CAN module enter bus-off, anyone who meet this issue or who can explain the relationship between optimization level and CAN bus-off? Thanks.
Hi@Ali22
From the register configuration you provided, the BUS-OFF state occurred and the ERRINT bit was set, but you did not enable the corresponding interrupt flags: CTRL1.BOFFMSK and CRTL1.ERRMSK
