Sorry to resurrect an old thread, but I’ve also recently started to experience 0x2d crashes, after 9 solid years of operation.
I recently upgraded from 2.1.5 to 2.2.0 (2). About a week later I got the 0x2d crash. I saw that it’s SDCard related, and since it’s the original SD card, and it’s 9 years old, I replaced the 128MB card with a 4GB card that I had around yesterday. This morning the Opensprinkler crashed again with the 0x2d error.
It seems odd that I’d get this on a new-ish card, so looking for any other suggestions or advice.
