Use the introduced functionality to read firmware files and flash their
contents into the device's internal flash memory to implement the devlink
flash update callback.
Sample output on EDS2 development board:
# devlink -j dev info i2c/1-0070 | jq '.[][]["versions"]["running"]'
{
"fw": "6026"
}
# devlink dev flash i2c/1-0070 file firmware_fw2.hex

Flash Update
|
|
============
|
|
|
|
The ``zl3073x`` driver implements support for flash update using the
|
|
``devlink-flash`` interface. It supports updating the device flash using a
|
|
combined flash image ("bundle") that contains multiple components (firmware
|
|
parts and configurations).
|
|
|
|
During the flash procedure, the standard firmware interface is not available,
|
|
so the driver unregisters all DPLLs and associated pins, and re-registers them
|
|
once the flash procedure is complete.
|
|
|
|
The driver does not support any overwrite mask flags.
