Hello everyone,

I'm working on a project for which we will need a bootloader for the
LPC2368 and possibly the LPC214X. The on-chip bootloader is
insufficient in a few ways:

requires jumper and reset to enter bootloader mode (not a big deal)
Flash magic/philips ISP utility will probably confuse many customers
Code is highly sensitive, we need a way to use encrypted files.

Can someone please point me to some good documentation and/or projects
involving bootloaders for the LPC2000 series?

Thanks

I had the same problem. I used the following setup:
- PC USB port
- CP2102 USB-to-serial converter
- LPCISP open source utility, modified to be user friendly and decrypt the encrypted hex file

End result is no jumpers or manual resets, easy to use, encrypted to some degree, and no need for the philips utility.

Thanks. So far we've got the first two steps the same. I'll look
into the LPCISP stuff, sounds promising. I've started doing some
testing with the USBXpress stuff from Silabs. Should save the
customer the trouble of looking COM numbers.

I like the approach the usb_fw_upgrader project implements:
http://www.tnkernel.com/usb_fw_upgrader.html

The port to LPC23xx would be fairly trivial. Also for Windows side driver
one can substitute the WinDDK USB Bulk sample project without to much
effort. I will be doing this myself fairly shortly.

Eric, did you do the encryption/decryption yourself ??
Or is this part of LPCISP ?? Is it LPCISP, or is it the
lpc2isp which has a yahoo group ?

Thanks,

----------------------

It is the LPC2ISP, available from the yahoogroup. I just added my own extremely simplistic encryption that at least prevents direct disassembly of the hex file.

Have a look at my Boot Loader Internals page at:

http://www.cse.unsw.edu.au/~jayas/esdk/lpc2/boot-loader.html

I also hava a on-chip loader for LPC that enables downloading and
running programs from (on-chip) memory (FLASH or SRAM) by simply copy
and paste of Intel format hex load files onto the window of a terminal
emulator like Hyperterm or Minicom.

The the program to check a target and install this loader is also
worth looking at. These can be found at:

http://www.cse.unsw.edu.au/~jayas/esdk/sill.html

Jaya

I tried to download the sill.exe to my computer but it just flashes a
dos screen for 250ms. Its a recent xp. The program looks promising if
I can get past step 1.

David,

You should start a "DOS Prompt" window (CMD.EXE) and run SILL.EXE as
per the transcripts on my tutorial page.

If you run by clicking on it from Windows Explorer, XP creates the DOS
Prompt window for you and runs SILL.EXE but closes this window as soon
as it exits.

You will not be able to see the transcript ... unless you have
photographic memory and can capture the screen in 250 ms you refer to!

Regards,

Jaya

wow. I made it to step 4 and it tells me it cant find a program called
com8. I don't blame it,neither do I. ??

Hello,

Sorry, you are not being coherent. Cut and paste the transcript.

SILL *never* tells you it cannot find a program. Either you have a
virus or you are very unfamiliar with using the CMD shell interface.

Good luck.

Hehe... Never say never eh, it's one of those words that kicks you when
you're not expecting it...
That said, Jaya should easily be able to tell you what's wrong as he wrote
the app you're trying to use. I'm assuming it's some misunderstanding of the
command line that needs to be used, but I don't have a copy to hand to check
the usage or make suggestions so I guess you'll have to wait for him to
reply.

Hello,

Where does it say "cannot find a program called COM8"?

I suggest you do some homework on interpreting Windows exit codes.
Perhaps Andrew Barney can help you with this.

Exit code 2 in Windows expands to "the system cannot find the file
specified".

It appears from your transcript that SILL failed to open COM8. I
would not blame SILL as it seems Windows could not find COM8 on your
system!

It looks like you are blindly copying the COM8 example in my tutorial
page. If you read fully, you will note that you have to first find
out what port your target is connected to on your system.

What I said stands. SILL *never* tells you it cannot find a program.

Jaya

Dear Andrew,

The OP does not appear to have the level of computer literacy required
to follow the tutorial example. I am trying to take him/her through
the steps so to achieve a positive outcome as I know there are others
listening to this forum in similar situation.

Your interjection is without substance. It is not constructive.
Perhaps it is appropriate for you to heed your own advice *never* do
this again so as to save yourself embarrassment in the future :)

Kind regards

Jaya
