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

[george]

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,

44      ENET_EVENT_BABR = BM_ENET_EIR_BABR,

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,

George

Hi George

for i.MX6Solo it is not valid.

It is valid for i.MX6SL (FEC_EIR register).

Hi George

all ENET_EIR register is valid in i.MX6-Solo,

please read 23.4.1 Interrupt Event Register (ENET_EIR)

IMX6SDLRM i.MX 6Solo/6DualLite Applications Processor Reference Manual

it gives valid ENET_EIR register description.
