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 ~$

root@iWave-G15S-SBC ~$

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

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 ?

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

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
