after dist-upgrade,my pogoplug can't running,the following is serial information,who can tell me what caused it, appreciate it!

to marvell engineer,I have a pogoplug on my hand,and find the big radiator panel very hot in the box,if  run long time,will it be problem?
what about you,other guys?

Hi,guys,after hacking kernel,I write a driver for tow green leds and two red leds, hope it helpful.
tested them under linux-2.6.30-rc6,and masked leds config in kirkwood_defconfig file,located in arch/arm/configs/
like this:
# CONFIG_MEMSTICK is not set
# CONFIG_ACCESSIBILITY is not set
CONFIG_NEW_LEDS=no
CONFIG_LEDS_CLASS=no

#
# LED drivers
#
# CONFIG_LEDS_PCA9532 is not set
CONFIG_LEDS_GPIO=no
CONFIG_LEDS_GPIO_PLATFORM=no
# CONFIG_LEDS_LP5521 is not set
# CONFIG_LEDS_PCA955X is not set
# CONFIG_LEDS_DAC124S085 is not set
# CONFIG_LEDS_BD2802 is not set

#
# LED Triggers
#
CONFIG_LEDS_TRIGGERS=no
CONFIG_LEDS_TRIGGER_HEARTBEAT=no
# CONFIG_LEDS_TRIGGER_BACKLIGHT is not set
CONFIG_LEDS_TRIGGER_DEFAULT_ON=no

Hi,Guys,I see someone talk about debugging with ftdi,but I directly seal a serial transiver to connect my board  with my pc, need no usb2serial cabale,how to config openOCD?

Hi,guys,I use linux-2.6.30.rc6 kernel source,and this version include leds class driver,but I just driver leds using char driver, class driver is complex,more depency, and confuse me,I like directly driver leds by ioctl function,simply.
     I try to write a driver for leds this weekend,and steps as following:
step 1, change kirkwood_defconfig file about led like this

CONFIG_NEW_LEDS=no
CONFIG_LEDS_CLASS=no

#
# LED drivers
#
# CONFIG_LEDS_PCA9532 is not set
CONFIG_LEDS_GPIO=no
CONFIG_LEDS_GPIO_PLATFORM=no
# CONFIG_LEDS_LP5521 is not set
# CONFIG_LEDS_PCA955X is not set
# CONFIG_LEDS_DAC124S085 is not set
# CONFIG_LEDS_BD2802 is not set

#
# LED Triggers
#
CONFIG_LEDS_TRIGGERS=no
CONFIG_LEDS_TRIGGER_HEARTBEAT=no
# CONFIG_LEDS_TRIGGER_BACKLIGHT is not set
CONFIG_LEDS_TRIGGER_DEFAULT_ON=no

step 2, write a driver for driving leds,mainly ioctl function in driver,like this,

static int globalmem_ioctl(struct inode *inodep, struct file *filp, unsigned
  int cmd, unsigned long arg)
{
    int ret=0;

  switch (cmd)
  {

       case LED_OF:
       case LED_ON:
     if (arg > GPIO_MAX) {
         return -EINVAL;
      }
     ret=gpio_direction_output(arg,cmd);//arg is pin number,rang frome 0 to GPIO_MAX-1=50-1
     break;   
   case GPIO_REQUEST:
     ret=gpio_request(arg, GPIO_REQUEST+0x30);
     break;
    default:
      ret =  - EINVAL;
  }
  return ret;
}

step 3,test my driver,

int main(int argc, char **argv)
{
   int i;
   int fd;
   char c;
   int rt=0;
   char record[IO_MAXNUM];

   fd = open("/dev/led_drv", 0);
   if (fd < 0)
   {
      perror("Failed to open leds");
      exit(1);
   }


      for(i=0;i<GPIO_MAX;i++)
      {
         rt=ioctl(fd, 1,  i); 
         if(rt!=0)
         {
            printf("GPIO%d request failure,continue next.",i);
            continue;
         }
         else { printf("GPIO%d request sucess.",i); getchar();}              
         
                                  }
                 close(fd);
                 return 0;
}

result:rt=ioctl(fd, 1,  i); return not 0,which should be caused by  ret=gpio_direction_output(arg,cmd);in driver,but why?
how to control GPIO,how to write GPIO register?

any body point me ? thanks.

Thank you for your pointing!

I do it as you said,but arise same issue, my rootfs is mounted by nfs ,will it cause the issue?who did experience it ?point me,thanks.

today,test sheeva-2.6.30-rc4-uImage and go into trouble.
I want to know new uImage need new u-boot to boot it, anybody point me in the right direction? thanks!

My god !I didn't notice st232 need 5V supply.
I  replace it with max3232 chip ,that's ok

SecureCRT 4.1,minicom,hypertiminal,all are not ok,maybe there is a hardware join issue?

Hi,guys,when i begin debug the board ,characters from uart  displayed on the console  is not recognized,who can tell me  how to resolve it,i will appreciate
charecters on console as following(photo in attach ):
