NMI pin and L138 boot

KB2603
Expert 1150 points
Other Parts Discussed in Thread: OMAP-L138

Hi,

Our custom board has the L138 NMI pin left open.

I have just read that if unused, this pin should be connected to a pull-up.

If the NMI pin is not connected, can it prevent the L138 from booting?

Thx

    Yes it could potentially prevent the L138 from booting. Are you seeing boot failures? Where is the PC stuck on the DSP and ARM?

    Jeff,

    OMAP-L138 specifies that there is a weak pull-up on the NMI pin by default. Can you confirm it?

    PC is stuck at 0xFFFD397C.

    Thx

    It looks like the DSP booted up successfully and started the ARM bootloader, so it probably isn't an issue with the NMI pin.

    What is the out put of the debug GEL?

    Jeff,

    Thx for your response.

    Here is the output of the GEL file. I am connecting to the target ARM and then load the debug GEL.

    It has an issue opening the NAND. Lets continue the discussion in your other thread rather than have so many open at the same time.
