There is definitely something funny going on with can1. I thought 3.3.001-285 ran ok but last week I got a flatbed alert from that version. So I've seen this problem with a wide range of recent versions including an edge version I did not build myself (downloaded from api.openvehicles.com). What's interesting is the same builds work without issue on my Cadillac, it's only the Corvette that gets into trouble. Given what I've tried so far I booted ovms-3.3.002-25 on the Corvette and have been getting flatbed alerts every 15 minutes since leaving home today (I think I have that turned off now). I can't easily capture the output of "can can1 status" until I get home and the module joins my home network (and "cut" from the messages page of the ovms iphone app is not implemented) but I see ~2M interrupts, 1.2M px pkts, 30 tx delays, 13K tx overflw, 840 tx fails. There are no err flags (0x00000000) and no other errors. This seems to indicate can1 transmission is broken for me. Craig
