Debugging
With traffic commands, use the –d option, which displays the BCM.0> shell. To check counters and if the link is up, use the ps
and show c commands.
nvramtool
To read and write the NVRAM bits that the BIOS uses to control testing and the bits for the EDA tools, use the nvramtool.
The NVRAM is an area, usually in a battery backed-up device such as an RTC chip, that allows the writing of bits which do not
change across reboots or power cycles. These bits are used to control how devices boot and how the tests are performed. The
nvramtool controls both the BIOS and EDA for testing. The bits are not common across platforms and are defined in the
configuration file. When using this tool, you must write the correct bits because the tool does not know the details of the
registers it is writing. The nvramtool can display the bit-level detail in the NVRAM registers, depending on how you define it in
the configuration file.
Tests
There are no tests of the NVRAM. This tool only controls the bits.
CLI Option
Dell Diag - NVRAM Tool
version 2.0
admin, 2014-10-01, bamboo-build-num
Syntax: ./nvramtool <option>
--h := show this help
--read [--reg=reg] := read all nvram values or at the reg location in nvram
--write <--reg=reg> <--val=value> := write nvram value
• read — Reads the register or registers in the NVRAM.
• write — Writes a value to the register or registers in the NVRAM.
