Question about i.MX6 Solo Interrupt Event Register (ENET_EIR)

Dear All,


We use i.MX6 Solo for our product.

Our original RTOS works on it.

We are writing the ethernet driver for i.MX6 solo now.


Please let me know about Interrupt Event Register (ENET_EIR).

The following descriptions are in a reference manual.

bit31 seems unused.

However, in SourceCode of SDK or Linux, it seems to be Heatbeat error event.


iMX6_platform_SDK/sdk/drivers/enet/enet.h :

42    enum {

43      ENET_EVENT_HBERR = 0x80000000,


iMX6_platform_SDK/sdk/drivers/enet/src/enet_drv.c :

483    if (value & ENET_EVENT_HBERR) {

484        printf("WARNGING[POLL]: Hearbeat error!\n");

485    }


Is actually this bit valid?

Do we need to watch this bit?


Best Regards,
