Nobody Cared issue

Raana — Wed, 03 Apr 2013 07:25:10 GMT

Hi,

Currently I am working on imx6DL processor (i.MX6Q/D/S)

Once Linux is launched,

If we are not doing anything on the board, after some times it's showing the below print but console is there.

root@iWave-G15S-SBC ~$ irq 402: nobody cared (try booting with the "irqpoll" option)

[<80045cd4>] (unwind_backtrace+0x0/0xf8) from [<800a5fec>] (__report_bad_irq+0x28/0xc4)

[<800a5fec>] (__report_bad_irq+0x28/0xc4) from [<800a6330>] (note_interrupt+0x1e4/0x240)

[<800a6330>] (note_interrupt+0x1e4/0x240) from [<800a51d4>] (irq_thread+0x1c4/0x1fc)

[<800a51d4>] (irq_thread+0x1c4/0x1fc) from [<80089468>] (kthread+0x80/0x88)

[<80089468>] (kthread+0x80/0x88) from [<8003fa64>] (kernel_thread_exit+0x0/0x8)

handlers:

[<800a49b0>] irq_default_primary_handler threaded [<802a1ec0>] pfuze_irq_thread

Disabling IRQ #402

root@iWave-G15S-SBC ~$

Is this an issue ??

How to recover from this ??

NOTE:

In my point of view, this issue is coming from PMIC, because irq 402 is for PMIC only

Thanks in Advance

Hello,Raana,

Please tell us which board you are using ? Is it our MX6 Dual Lite SABRE AI CPU Card ?

Hello,Raana,

Is the PMIC MMPF0100 ? Could you tell me which GPIO pin pmic's INT is connected to ?

Hi Weidong,

No, I am using Freescale PMIC (pfuze100)

Issue solved after configuring the proper PMIC interrupt GPIO (GPIO_7_13).

Thanks for your support

ok, Raana,

It means that PMIC interrupt on cusotmer board is not different from that of FSL Evk board,So you ajusted PMIC interrupt to be GPIO_7_13(customer uses it) , then the issue is resovled.

Rgiht ?

Yes, Weidong,

PMIC interuupt GPIO of the Customer board is also same as EVK board.

So, the Issue solved, after configuring the proper PMIC interrupt GPIO (GPIO_7_13) pin.

Thanks for your support
