Hello, 'last' is a handy tool, and using it for 'last reboot' provides a nice log. I was wondering if there are currently any platforms where more information about the reboot type is supported? For instance on the Zynq UltraScale+ devices there are a variety of reboot reasons: https://www.xilinx.com/html_docs/registers/ug1087/crl_apb___reset_reason.html# So on each startup the reason could be read and logged before resting the register[1]. I guess one tricky issue would be the kernel interface, for a test I was just using memtool like this: # memtool md 0xFF5E0220+1 ff5e0220: 00000001 Where 00000001 indicates an 'External POR', but this probably isn't how we'd want to do it. I'm not subscribed to the mailing-list so please cc me any response. thanks, Paul [1] If the register is not reset then multiple bits can accumulate so you wouldn't now which is correct for the current boot
