annoying Buzzer Problem in TMDXEVM437X

purush mv

I am just getting started with TMDXEVM437X. While I was trying to figure out how to flash the nand in the card. The on board buzzer went off before I could even start programming the nand flash.

The buzzer is in always on mode so shutting down and restarting doesn't help

It makes the sound when ever I power on the card.I guess there is a latch up.

How do I disable it ?

Hi,

The buzzer is controlled from a GPIO and should be off by default. Something's probably damaged on your board. You can find the board schematics here: http://processors.wiki.ti.com/index.php/AM437X_EVM_Boards#AM437x_General_Purpose_EVM

i guess there is some problem with the card. For now i got it working back by removing the connection to vbat. Thank you !
