NMI pin and L138 boot

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

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

KB

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

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.
