Hello,

Does anyone know if FLASH read protect( 0x1FC with value 
0x87654321 ) really works?

Is there a work arround it to get to memory?

Thanks,

Gus

Hi Gus,

This is a very interesting article on reverse engineering:

Hi Gus,
Yes, it does work, however, note the following:
 
It's only supported on 64-pin/144-pin LPC2000 devices with a Boot Loader ID
>= 1.6  (you can check your device's ID using Ashlings FlashLPC utility or
the Philips FlashISP utility). 
 
Code read protection is enabled by programming the flash address location
0x1FC (User flash sector 0) with value 0x87654321 (2271560481 Decimal). If
Read Protection is enabled then the device has to be fully erased (thus
disabling Read Protection) before it can be re-programmed. In addition, you
will not be able to "connect" to the device via JTAG, hence, erasing must be
done using FlashLPC/FlashISP.

Hi folks... I'm coming from AVR land, (because of defective Atmel
silicon and looking at these LPC parts),  and see that writing 0x1fc 
with 0x87654321 (sector 0 ?) protects the flash from being read.

I am curious if this is actually documented by Philips or somewhere
else.

I cannot seem to find any references to it except on forums etc...

Thanks,
bob

We are also moving to the LPC parts because of problems with the avr. 
For my interest, was your problems with the avr corruption of flash 
code at boot up ??

Hi Bob,
 
Rest assured that flash protection works and is endorsed by Philips; they
are working on the docs AFAIK. . See the FAQ on our site for some important
information:
 <http://www.ashling.com/support/lpc2000/knowledge_base.html>
http://www.ashling.com/support/lpc2000/knowledge_base.html. In particular,
the section " <http://www.ashling.com/support/lpc2000/knowledge_base.html#>
How do I enable LPC2000 Flash Read protection? "

The reason I am interested in looking at other parts are because of 
Atmels bad silicon on the ATmega32,64, and 128 parts and Atmels poor 
response to customers problems.   The parts don't work at 16 MHz and 
sometimes down to even 10 or 12 MHz when warm.

Yes, thank you... I found that link easily on Google, but I wondered 
why Philips would now have that very important information in their 
documentation or even on their web site.  I believe I had seen a 
message from Philips regarding the issue though on some other web 
forum.

thanks,
bob

Hi all,

Out of curiousity, I've put in an ORG directive to
place 0x87654321 at address 0x1FC in Flash to see if 
the code protection works.
Reading the code back and comparing with Bootloader
is succesful - thus the part isn't protected.
I'm using an LPC2119 Bootloader ID = 1.6.

Anyone know what I'm doing wrong ?
I thought these parts had protection in there ?

Hi Kris,

take a look at the usermanual(2004-05-03) at page 269.
Sorry your bootloader version must be 1.61 or higher.

Andreas

Thanks Andreas !
Too many things to look at all at the same time :-)

Hi All

While waiting for my LPC2106 board to arrive (Thanks for all the help on my
former topic around the LPC2106 processor!!!) I'm now very interessted in
the LPC2214 (because of the ext. mem interface, more IO and pheripals)

How ever some questions came to me last night while drawing the LPC2214 into
protel

1. The BSLx pins, all memory IC's i've used had a software bank select are
these pins used to hardware select banks on large memory devices, if yes
could you recommend any compatible ?

2. I would like to use all 8 pins of the ADC but these are mapped to BSL
pins 2 / 3 This means (if im correct) that
any memory i connect cant use more than BANK 0 and 1 because i want BANK2+3
used for the ADC

3.
I had this in mind:
I saw that BOOT could be set so that CS0 would select a bootable flash
insted of the internal (very smart)
On default the device boots from the external flash, (CS0) it is then
possible to "invoke" a special bootload where the
BOOT pins are shifted so that the LPC boots from internal flash where a
"bootloader" programs the external flash, maybe from GPRS,UART or some other
source and then when finished it sets the BOOT pins for external flash and
resets it self
(all this should be done with an external chip im thinking ATmega8515 or
something similar)

4.
From past experience with ARM that I was able to specify the bandwidth of
the databus/address bus
I am probertly not going to use any external devices with more than 16 data
and 20 address pins.
(unless you guys know some fancy part which is a must have :) so is it
possible to specify (for instance)

5.
I have a device on CS0, it has 16 data and 20 address pins, this is the
largest part in my design
can I then allocate the rest of the data pins as GPIO and the rest of the
address pins as general purpose outputs ?

6.
Can I use all the TRACExxx, PIPExxxx pins as general purpose pins (ofcause
respecting their fixed I/O setting) ?

7.
Wanting to add a regular JTAG (not the fancy one with a million pins) for
programming the internal flash
can I use Leon Heller's schematic as a reference
(Files->Hardware->JTAG->Jtag.pdf) ??

8.
Why in god's name did philips select the DCD pin which is an input on the
modem interface for sampling the bootloader
I think this is the worst pin possible to select, it renders this pin on the
modem interface useless unless i want to add a bunch of extra components,
Shame on you philips, there are other pins, use them insted !

9.
Can any one suggest some compatible flash or ram devices for the LPC2214 ???

Thanks for reading !

Best regards
Lasse Madsen

I've recently started programming with the arm devices and specifically the
Philips LPC2194 device. I'm running the sample programs supplied in the
Ashling Development system. I'm trying to store some of the programs in
flash instead of ram.

I've tried to use the LPC2000 Flash Utility and the Flash LPC program from
Ashling but both programs require hex file types. How do I convert elf/dwarf
files to hex format. Is there a conversion program? I can't find any options
within the Ashling Development Environment (AsIDE) to output hex files
instead of elf files.

Thanks in advance
Pauric

Hi Pauric,
Details are on our FAQ page. 
 
http://www.ashling.com/support/lpc2000/knowledge_base.html
 
Look for the question:
 
 <http://www.ashling.com/support/lpc2000/knowledge_base.html#> How do I
generate an Intel-Hex-format output file ?
By default, AsIDE will tell the GNU Linker to produce an ELF format output
file. If you.....
