Continuous beep

Kourosh
Hi,

I have bought a mini 2440. By power on, a continuous beep is heard. What is
 the problem of board?

Thanks in advance.

Check the position of the boot switch. If in the SD card position and no SD
card inserted, it does this.

Juergen Beisert
The Mini2440 has no "SD card postion" for the switch you mentioned. The
Mini6410 has.

The Mini2440 can boot from its attached NOR or NAND flash memory. Try both
with its boot switch. If there is still the beep and nothing else happens,
your Mini2440 seems broken or at least the bootlader is corrupt.

Dave McLaughlin
Ah of course. I was forgetting this was the 2440. 

Sorry!

Kourosh
Thank you for your helps. I tried both positions, the beep still exists.

Would it be possible that I download bootloader from PC?

Is the mini2440 brand-new or used?

I have ran a few successful codes on my mini2440. I was trying to read
potentiometer values from AIN1 pin on the board. It was done properly once.
Now, whenever the board is powered on in NAND mode, it gives a short beep.
Whenever any gpio pin is set to value '1' even to glow an LED, it gives a
continuous beep until the power is turned OFF. Can you help me resolve the
problem?
Thanks & Regards

You really need to be looking at the messages on a terminal program running
on your Linux host while it is booting up.

So, there is a short beep on power up, the unit appears to boot up properly
then whenever you run your program to set any gpio to '1' ....

Short beep on bootup, which never happened before.  Which distro are you
running?  Sounds to me like the PWM function has been enabled somehow, ie
by a corrupted kernel image??  Can you re-load in your kernel?

Thanks for your reply!
I reloaded my kernel image and the bootloader, and for now the beeping
seems to have stopped.
