@deffn {Flash Driver} lpc2900
|
||||
This driver supports the LPC29xx ARM968E based microcontroller family
|
||||
from NXP.
|
||||
|
||||
The predefined parameters @var{base}, @var{size}, @var{chip_width} and
|
||||
@var{bus_width} of the @code{flash bank} command are ignored. Flash size and
|
||||
sector layout are auto-configured by the driver.
|
||||
The driver has one additional mandatory parameter: The CPU clock rate
|
||||
(in kHz) at the time the flash operations will take place. Most of the time this
|
||||
will not be the crystal frequency, but a higher PLL frequency. The
|
||||
@code{reset-init} event handler in the board script is usually the place where
|
||||
you start the PLL.
|
||||
|
||||
The driver rejects flashless devices (currently the LPC2930).
|
||||
|
||||
The EEPROM in LPC2900 devices is not mapped directly into the address space.
|
||||
It must be handled much more like NAND flash memory, and will therefore be
|
||||
handled by a separate @code{lpc2900_eeprom} driver (not yet available).
|
||||
|
||||
Sector protection in terms of the LPC2900 is handled transparently. Every time a
|
||||
sector needs to be erased or programmed, it is automatically unprotected.
|
||||
What is shown as protection status in the @code{flash info} command, is
|
||||
actually the LPC2900 @emph{sector security}. This is a mechanism to prevent a
|
||||
sector from ever being erased or programmed again. As this is an irreversible
|
||||
mechanism, it is handled by a special command (@code{lpc2900 secure_sector}),
|
||||
and not by the standard @code{flash protect} command.
|
||||
|
||||
Example for a 125 MHz clock frequency:
|
||||
@example
|
||||
flash bank lpc2900 0 0 0 0 $_TARGETNAME 125000
|
||||
@end example
|
||||
|
||||
Some @code{lpc2900}-specific commands are defined. In the following command list,
|
||||
the @var{bank} parameter is the bank number as obtained by the
|
||||
@code{flash banks} command.
|
||||
|
||||
@deffn Command {lpc2900 signature} bank
|
||||
Calculates a 128-bit hash value, the @emph{signature}, from the whole flash
|
||||
content. This is a hardware feature of the flash block, hence the calculation is
|
||||
very fast. You may use this to verify the content of a programmed device against
|
||||
a known signature.
|
||||
Example:
|
||||
@example
|
||||
lpc2900 signature 0
|
||||
signature: 0x5f40cdc8:0xc64e592e:0x10490f89:0x32a0f317
|
||||
@end example
|
||||
@end deffn
|
||||
|
||||
@deffn Command {lpc2900 read_custom} bank filename
|
||||
Reads the 912 bytes of customer information from the flash index sector, and
|
||||
saves it to a file in binary format.
|
||||
Example:
|
||||
@example
|
||||
lpc2900 read_custom 0 /path_to/customer_info.bin
|
||||
@end example
|
||||
@end deffn
|
||||
|
||||
The index sector of the flash is a @emph{write-only} sector. It cannot be
|
||||
erased! In order to guard against unintentional write access, all following
|
||||
commands need to be preceeded by a successful call to the @code{password}
|
||||
command:
|
||||
|
||||
@deffn Command {lpc2900 password} bank password
|
||||
You need to use this command right before each of the following commands:
|
||||
@code{lpc2900 write_custom}, @code{lpc2900 secure_sector},
|
||||
@code{lpc2900 secure_jtag}.
|
||||
|
||||
The password string is fixed to "I_know_what_I_am_doing".
|
||||
Example:
|
||||
@example
|
||||
lpc2900 password 0 I_know_what_I_am_doing
|
||||
Potentially dangerous operation allowed in next command!
|
||||
@end example
|
||||
@end deffn
|
||||
|
||||
@deffn Command {lpc2900 write_custom} bank filename type
|
||||
Writes the content of the file into the customer info space of the flash index
|
||||
sector. The filetype can be specified with the @var{type} field. Possible values
|
||||
for @var{type} are: @var{bin} (binary), @var{ihex} (Intel hex format),
|
||||
@var{elf} (ELF binary) or @var{s19} (Motorola S-records). The file must
|
||||
contain a single section, and the contained data length must be exactly
|
||||
912 bytes.
|
||||
@quotation Attention
|
||||
This cannot be reverted! Be careful!

||||

|
||||
Example:
|

@example

||||
@end example
|
||||
@end deffn
|
||||
|
||||
@deffn Command {lpc2900 secure_sector} bank first last
|
||||
Secures the sector range from @var{first} to @var{last} (including) against
|
||||
further program and erase operations. The sector security will be effective
|
||||
after the next power cycle.
|
||||
@quotation Attention
|
||||
This cannot be reverted! Be careful!
|
||||
@end quotation
|
||||
Secured sectors appear as @emph{protected} in the @code{flash info} command.
|
||||
Example:
|
||||
@example
|
||||
lpc2900 secure_sector 0 1 1
|
||||
flash info 0
|
||||
#0 : lpc2900 at 0x20000000, size 0x000c0000, (...)
|
||||
# 0: 0x00000000 (0x2000 8kB) not protected
|
||||
# 1: 0x00002000 (0x2000 8kB) protected
|
||||
# 2: 0x00004000 (0x2000 8kB) not protected
|
||||
@end example
|
||||
@end deffn
|
||||
|
||||
@deffn Command {lpc2900 secure_jtag} bank
|
||||
Irreversibly disable the JTAG port. The new JTAG security setting will be
|
||||
effective after the next power cycle.
