• frame—Display an individual stack frame.
• sysret—Display return information from the last booted system image. This
information includes the reason for terminating the image, a stack dump of
up to eight frames, and, if an exception is involved, the address where the
exception occurred. For example:
rommon 8> sysret
System Return Info:
count: 19, reason: user break
pc:0x801111b0, error address: 0x801111b0
Stack Trace:
FP: 0x80005ea8, PC: 0x801111b0

• meminfo—Display size in bytes, starting address, available range of main
memory, the starting point and size of packet memory, and size of nonvolatile
random-access memory (NVRAM). For example:
rommon 3> meminfo
Main memory size: 64 MB.
Available main memory starts at 0x10000, size 65472KB
IO (packet) memory size: 25 percent of main memory.
NVRAM size: 32KB
