I'm on an old RPi B (maybe a B+). It's pretty ancient, so I might be pushing my luck. Here's my CPU info:
pi@raspberrypi:~ $ cat /proc/cpuinfo processor : 0 model name : ARMv6-compatible processor rev 7 (v6l) BogoMIPS : 697.95 Features : half thumb fastmult vfp edsp java tls CPU implementer : 0x41 CPU architecture: 7 CPU variant : 0x0 CPU part : 0xb76 CPU revision : 7 Hardware : BCM2835 Revision : 000e Serial : 00000000e9b1ce2d Model : Raspberry Pi Model B Rev 2 Running GDB gives the illegal instruction as <UNDEFINED> instruction: 0xf57ff05a which looks to be a "Data Memory Barrier" instruction? Sounds like a plausible culprit. Thanks! On Tuesday, August 11, 2020 at 2:14:28 PM UTC-7, Matthew Flatt wrote: > > Which model Pi are you using?
