I have some customized boards(based on omap3evm), they may froze once per day randomly. When it's frozen, JTAG is not able to connect to it, only after a system reset, I can reconnect to it. I put some IRQ related trace in the static RAM, so I can read these traces after a system reset, I noticed the last thing the board did before frozen is 2 nested interrupts( uart2 and gp timer), is there any known issue about nested interrupt ?
