I have a LPC936. I will to program with the unmodified version of the bridge code.

Hi Andy,

The bridge code version is 1.7(I think). I modified this code to use in LPC921 as bridge.

Hi Andy,

  When I was developing my LPC900 programmer (one year ago), I had exactly this problem: I couldn't to erase the LPC915 memory flash using Global Erase. FM showed this message:Operation Failed. (erase device).

  I reported this problem to local office from Philips and they contacted Bauke. They told me that Bauke commented a similar problem with the LPC, but I have no more details about it.
  I think that similar problem with FM means trying the command global erase in a LPC900 and this command failure.

   I didn't take care about it a one year ago. But, this problem happen again in this project.

Hi Andy,

No, who contact Bauke was local office. I don't know Bauke e-mail.

Hi friends,

  I don't have idea about to resolve this problem. So, I will remove the mcu.

Hi Andy, Thanks for reply,

  The LPC915 don't use ISP. Use only ICP mode.

In menu: Options -> Advanced Options -> Security Tab
Uncheck "Protect ISP" is not possible. This option is disable when I select LPC915.

I choose another mcu and do your recommendations. Protect ISP was Uncheck. Then I go back and select LPC915. The Protect ISP is unchecked.
I try global erase, but the problem is the same.

  I think that my bridge have some bug. I contacted local office, and They contacted Bauke, that wrote the bridge code. He commented a similar problem, but I don't  have more news about it.

Hi Andy,

  Yes, before to set security bits, I could erase any block, but global erase never run in LPC915. To erase all blocks, I did select all blocks and run command erase in the FM.
I had set security bit 0 and bit 1. Then, when I wanted to program again, I select erase all blocks (not global erase), and the FM could do it without problems.

LPC9xx/LPC9xxx / Can't erase Security bits
December 10, 2007, 03:43:43 PM
Hi friends! ;D

  I was happy with my project. It was running fine. But, I set the security bits (bit 0, bit 1 and bit 2) in many blocks and I can't erase ou programmer it again.
  I'm using lpc915.  I am using self made Hardware (like MCB900) in ICP mode. The bridge code is version 1.7 ,in a LPC921.

  The bridge works fine (I think). I read device signature, Blank check, etc. But, I can't to erase (global erase) in LPC915.
  In LPC936, I erase all memory (Global erase). It's work fine. But in LPC915, the FM show: Operation Failed.(erasing device).
  In command line, the problem is the same:

F:\>fm @lpc915teste.txt
Flash Magic Version 4.02.260
8051/XA Driver Version 2.41.258
ARM Driver Version 1.32.260

Device selected
Manufacturer ID: 0x15
Device ID 1: 0xDD
Device ID 2: 0x17
Erase failed: invalid command - Operation Failed. (erasing device) (DEVICE)

The file is:

DEVICE(89LPC915,7.372)

COM(2,19200) HARDWARE(KEILMCB900, 250, 300) ERASE(DEVICE, PROTECTISP)
ERASE(1, PROTECTISP)
ERASEUSED(Pul.hex, PROTECTISP)
HEXFILE(Pul.hex, NOCHECKSUMS, NOFILL, PROTECTISP)

  So, how can I erase the Security bits in LPC915?  :'(

   thank for help !

Hi people !

I'm working with the LPC915 and a strange problem happened. When I set the lock bits (bit 0) block 0 and 1, the P0.1 and P1.0 don't work.
I have a LED in P0.1 and a simple output in P1.0.
I need these pins for the signal output.

What's happening ?

Does someone have the same problem ?

Thanks in advanced.
