Hi All,
I am using LPC114 in my project and wanted to know what are the different methods of programming the LPC1114 in production. We will be programming the device before it is layed down on the pcb.

I have seen that the falshmiagic license has to be bought for it to be used in production.

Is there any other way to programme the the release image (hex file) onto the device ?

Can we use lpcexpresso to programe the hex file ?

Regards,
Syed

Thanks for the link. Does it not support programming a hex file ?

Reagrds,
Syed

I think it would be easier to program the device after it is on the PCB. You can definitely use LPCXpresso and the LPC-Link in that case as long as you have brought out the SWD lines to a header.

AFAIK, it is executable (.axf) and binary file only.

Why do you need hex?

Thanks everyone for your help. The only reason for hex file is that we can have a single image which can be used with flashmagic and lpc expresso.

I agree with Larry: programming the device onboard is much simpler than doing this before soldering.
For production purposes, go for Red Suite 3 and a RedProbe+ it is not only faster than the free LPCXpresso tools plus an LPC-link but with Red Suite 3 you also have a stand alone flash programmer tool. Less 'tool' means less chance of errors during production.
I prefer tools command line tools that you can embed in your own production environment. Automation makes production faster and more reliable.

Of course you need to make the SWD pins somehow available on test pads.
It's always a good idea to do this so you have the option of reprogramming existing devices when you discover a bug (yes, there will be bugs, there will always be bugs...)

Regards,

Rob

Yes, you can.

User manual:

Quote:

CRP2 0x87654321 Access to chip via the SWD pins is disabled. The following ISP commands are disabled:
• Read Memory
• Write to RAM
• Go
• Copy RAM to flash
• Compare
When CRP2 is enabled the ISP erase command only allows erasure of all user sectors.

so "Access to chip via the SWD pins is disabled"
will take place only after a power on cycle, following ISP flash programming
isn't it?

Regarding to the original topic of programming the device in production, I think below are the different options availiable

1) LPCXpresso tools and LPC-link
- No cost or license fee
-also contains command line flash programming tool [B]crt_emu_lpc11_13
- [/B]file format supported: axf, bin

2) FlashMagic
- License fee :399 Euros
- file format: hex

3) Red Suite 3 and RedProbe+
- Cost : $256 for 256k download limit and additional cost of RedProbe+

Please confirm if this is correct or are there any more options.

Regards,
Syed

Yes, you are even able to debug after programming. But after power cycle fun is over and you have to use FlashMagic...

There is LPC21ISP utility which supports LPC13xx and possibly may be used for LPC11xx but I'm not sure.

Versaloon claims to support SWD and LPC1000:
http://www.versaloon.com/doc/versaloon/doc_versaloon_programmer_platform.html
You can buy it from the developer or make your own:

Or you can reprogram an STM Discovery board:
