11 Ramoops is an oops/panic logger that writes its logs to RAM before the system
12 crashes. It works by logging oopses and panics in a circular buffer. Ramoops
16 Ramoops concepts
19 Ramoops uses a predefined memory area to store the dump. The start and size
54 Ramoops also supports software ECC protection of persistent memory regions.
62 Setting the ramoops parameters can be done in several different manners:
66 boot and then use the reserved memory for ramoops. For example, assuming a
69 ramoops region at 128 MB boundary::
71 mem=128M ramoops.mem_address=0x8000000 ramoops.ecc=1
