Philipp, I faced the same problem with the Zoom AM1808 board we received from TI's sales representatives. They substituted our EVM with a new one, and this new board works very good. I could not conduct any serious investigation on the faulty board, but I can suggest you to make some verification on thermal effects as the possible cause. Please, try to selectively cool the AM1808-SOM-M1 module (with a fan or cooling spray) Please, let we know any results you could find

Hi all, I am trying to do some development on the Zoom AM1808 EVM from LogicPD. The demo appears to boot just fine since the demo loads and I can interact with the screen, login over UART and telnet. However, after half a minute to a minute the board stops responding; the screen goes blank and it doesn't respond to any input anymore. I'm really not sure whether it's a kernel crash or some other issue. I do get various errors such as: "Unable to handle kernel paging request at virtual address e3120004 pgd = c1ffc000 [e3120004] *pgd=00000000 Internal error: Oops: 5 [#1] PREEMPT" "udevd[528]: inotify_add_watch(3, (null), 10) failed: Bad address" "Internal error: Oops - undefined instruction: 0 [#1] PREEMPT" I am unsure if they point to the real problem though. If anyone has encountered something like this, I'd appreciate any ideas. Thanks, Philipp
