Load Flash
lf [-o[=]<offset> [-k]]
... [-m[=]<adr> -l[=]<len>]
where:
lf
command
-o
option: offset
<offset>
parameter: value: hexadecimal
program to FLASH offset of ...
-k
option: keep
retain surrounding contents
-m
option: memory (address)
<adr>
parameter: value: hexadecimal
absolute address of image to be programmed
-l
option: length
<len>
parameter: value: hexadecimal
length of image to be programmed
Without parameters, the FLASH is programmed using the contents of
the data buffer. If no image is available in the data buffer, the FLASH
programming is terminated.
If no offset option ("-o") is specified the image is considered to be
valid and is therefore added along with CRC and length information.
If the CRC is determined to be valid during the next startup, the
image is copied to the absolute address 0x0 and started at 0x100
after the boot wait time has been exceeded.
Normally, the local data buffer holds the image to be programmed.
However, if the "-m" and "-l" parameters are specified, the image is
programmed from the absolute address specified.
If "<offset>" is specified, the contents are programmed exactly at this
offset in FLASH. No length and no CRC information is added.
The "-k" option can be specified to prevent deletion of the
surrounding FLASH contents.
