Started by topandurangs March 23, 2006
Hi all,

     I have two LPC2136 chips,in which when i am reading there part id 
through Philips downloader utility i am getting part id as 2131.
     what is it mean? also when i try to download my code in it ,it 
gives error insufficient flash.
     I guess it is problem from philips.
     How to overcome this problem?

I think the obvious answer is that they are 2131s? The Flash utility says they are plus they do not have the memory of the larger 2136. How are they branded, have you checked? Hint! If you cannot read/load more than 32K of Flash then they are 2131s! *Peter* topandurangs wrote: >> I have two LPC2136 chips,in which when i am reading there part id through Philips downloader utility i am getting part id as 2131. >> what is it mean? also when i try to download my code in it ,it gives error insufficient flash. >> I guess it is problem from philips. >> How to overcome this problem?

Hello, can you post the id itself, so you can decide if the chip's answer is wrong or the software on pc is identifying the wrong chip. As you can see on http://guest.engelschall.com/~martin/lpc21xx/lpc_ids/index.html the id for the chip should be the following: LPC2131: 0x0002FF01 -> 196353 LPC2132: 0x0002FF11 -> 196369 LPC2134: 0x0002FF12 -> 196370 LPC2136: 0x0002FF23 -> 196387 Regards, Martin ----- Original Message ----- From: "Pandurang Shinde" To: Sent: Sunday, March 26, 2006 2:16 PM Subject: RE: [lpc2000] Re: read wrong part id of lpc2136 > thanks Peter for reply, on the chip it is printed as > > LPC2136FBD64 > > S60735.1 04 > > ZPG0602B > > So i am concludung that is LPC2136 only ,but reading > LPC2131. > Why this happen. > Can u suggest any solution for it. > > Regards, > Pandurang S. > > ________________________________ > > From: l...@yahoogroups.com on behalf of Peter Jakacki > Sent: Sun 3/26/2006 4:36 PM > To: l...@yahoogroups.com > Subject: Re: [lpc2000] Re: read wrong part id of lpc2136 > I think the obvious answer is that they are 2131s?

It is possible that it is branded incorrectly or that an incorrect ID has been loaded. What you can do is to construct a 32K dummy file to confirm that it does load and then step it up to 64K, 128K and so on until you ascertain the memory size. Once you are sure of your facts you can go back to your supplier to rectify the situation. Either way, let us know what you found out. *Peter* Pandurang Shinde wrote: > thanks Peter for reply, on the chip it is printed as > LPC2136FBD64 > S60735.1 04 > ZPG0602B > > So i am concludung that is LPC2136 only ,but reading LPC2131. > Why this happen. > Can u suggest any solution for it.

Hello Pandurang Shinde, Is it only one chip, or do you have several with the same problem? I will look into this problem, Gerrit de Waard, Product Enigineer Microcontrollers Philips Semicondictors --- In l...@yahoogroups.com, Peter Jakacki wrote: > > It is possible that it is branded incorrectly or that an incorrect ID > has been loaded.
