Using LPCXpresso 3.8.2 [Build 129],  OS: Gentoo, kernel 2.6.38-gentoo-r3 

I get CRP1 (0x12345678) programmed when I flashing LPC1343 using LPC-Link. There are no CRP active option  in binary I flash into device. ([0x000002fc]==0xffffffff)

However, device is locked after power cycle. 

Also if I start debugger, after IDE flashes my code and stops at RESET (i.e. no my code has been executed) I see  0x12345678 at 0x2fc.

I tried to flash my part using only command-line tools:

1. LPC-Link attached to clear device and system is powered on

2. loading firmware into LPC-Link and checking SWD connection...

3. Ensuring my code has no CRP:

(OK) - I see 0xffffffff at 0x2fc

4. Flashing...

5. Checking my device is up and running - you should beleive me, it's OK - no printable output to paste here

6. Checking SWD is still work...

7. Cycling device power or just doing hardware reset. Device is up and running again

8. Reloading LPC-Link firmware after previous power cycle (step 7)

Now I haven't SWD working. 

10. Finally if I switch my locked device into ISP i can see mass storage device marked with Volume label CRP1_ENABLD

11. Now if i write my binary in ISP mode device will be unlocked. (Until next flashing via SWD)

I have two LPC1343, all this parts locks when I tried SWD-flashing.

What I did wrong? All worked fine for me before I updated my Linux.

Yes, I know that Gentoo distribution is not supported officially. I beleive I will find workaround - a week ago all worked fine. Will try revert recent system updates to find one that broke compatibility.  Anyway, thanks for your answer! 

Another my question is about acceptable parameters for option -flash-protect= . There are not enough info in [I]crt_emu_lpc11_13_nxp -h[/I] output.
Can you show me what values for -flash-protect= corresponds to CRP1 ENABLED, CRP DISABLED, etc.?


First, be certain you understand the consequences when using any CRP setting. These settings are communicated to the debug utility as follows:

CRP1 is  '-flash-protect=1'
CRP2 is  '-flash-protect=2'
CRP3 is  '-flash-protect=3'

Any other flash protect setting is invalid, and ignored. If you happen to have a CRP word embedded in your image, an error results if  it doesn't match the protect setting on the command-line. Note also, unless you use a valid '-flash-protect=' setting you'll not be warned your image contains a CRP word.

The supported Linux platforms for LPCXpresso IDE are Ubuntu 9/10/11 and Fedora 12/13. LPCXpresso [B]may[/B] install and run on other Linux distributions.  However, only the distributions listed above have been tested. We have  no plans to officially support other distributions at this time.

Thus your platform (Gentoo) is not a supported one, and we do not see this problem with any of the supported platforms (Windows or Linux). Thus I'm afraid that you are pretty much on your own here. Sorry.

Regards,
CodeRedSupport.
