Hello people,
I switched to the new DM3730 from IGEP and while it's supposed to be
(almost) the same as the 3530 Version the isp deadlocks
deterministically after I start capturing the second time with yavta.
All extra locking debug output is enabled in the kernel .config.
I am unsure if this is an ISP thing or a problem in the
interrupthandling software.
The first block is the watchdog that detects the deadlock. The last
block is in the isp-code but how can it hang when trying to UNlock a
spinlock? I am unsure about the 2nd block.
The assembler code of __irq_svc is located in arch/arm/kernel/entry-armv.S
Maybe I should try on linux-arm@xxxxxxxxxxxxxxxxxxxxxx but I thought I
give it a shot here first.
I use the omap3isp-2.6.35.3-omap3isp branch from Laurent.
Any ideas? Thanks for any help,
Bastian Hecht
