analog604 Posted December 27, 2012 Report Share Posted December 27, 2012 (edited) Hi! For the MIOS32 application can the part 'OM13000,598 EA LPCXpresso board' be used?http://www.mouser.com/ProductDetail/NXP-Semiconductors/OM13000598/?qs=sGAEpiMZZMvnfWYzRsH6EalhGIo7K5FV The CORE_LPC17 parts list calls for this part: 924-EA-XPR-003http://www.mouser.com/ProductDetail/Embedded-Artists/EA-XPR-003/?qs=%2fha2pyFaduhMwvcOQY%252bGaNnHo0HkMd41OYuxozzmBHYezV4g6jXmfw%3d%3d So I had made a mistake and ordered the 'EA LPCXpresso board' which contains the LPC1769 and rev B of the board. It costs a few dollars less. Successfully programmed the MIOS32 bootloader with positive indicators including the 3 pulse fades of the LED. I just don't have the CORE_LPC17 PCB to try out MIOS32 apps yet. If no one knows for certain, I'll report back my findings! -Jay [edit: corrected links] Edited December 29, 2012 by analog604 Quote Link to comment Share on other sites More sharing options...
Shuriken Posted December 28, 2012 Report Share Posted December 28, 2012 The links both go to the same page. But if i search on 924-EA-XPR-003, you get the Embedded Artists Manufacturer, as the link shared is for the NXP one. I don't think there is any difference. Both are the LPCXpresso LPC1769 board.

kpete Posted December 28, 2012 Report Share Posted December 28, 2012 If you compare pictures between the right one and the wrong one, the main difference is the pin layout at one end of the board. I tried to find documents on the one you ordered but couldn't find anything to do the pin compare of the pin matrix of the 6x9 pins on the right edge. The good part can be found at http://www.mouser.com/ProductDetail/Embedded-Artists/EA-XPR-003/?qs=S92LKl1JvFyxqKp2Q1rskQ== and it includes a link to a PDF document that has the pin assignments. I don't know if your board will work but just comparing the pictures, the board you have has far fewer parts. And I have found it difficult to find the right part if you just enter “LPC1769†in the mouser search window. Now wonder you ended up with a different board.

Images are for reference only. If you look closely the image is for an LPCXpresso LPC1343. The Partnr. OM13000,598 is for LPC1769. The NPX website says, however it seems some of the links point to an old description claiming it to be a LPC1768 board. Quote Link to comment Share on other sites More sharing options...

But the real problem might be that the proper board was made by “Embedded Artists†while the one he ordered was manufactured by “NXP Semiconductorsâ€. The real question is are they 100% compatible as far as function and pin layout. The image that is shown for the LPCXPRESSO LPC1769 from Embedded Artists that I bought for my MIDIO128 V3 project matches the image shown in the Mouser web site. BTW-Both boards use the same LPC1769 processor. Edited December 28, 2012 by kpete Quote Link to comment Share on other sites More sharing options...
Shuriken Posted December 29, 2012 Report Share Posted December 29, 2012 (edited) If you looked at the link to the NXP website, partnumber OM13000,598 has as a description: LPCXpresso Board for LPC1769. NXP also sells the EA LPCXpresso BaseBoard. Personally i don't think there are two different boards with the same name called LPCXpresso Board for LPC1769.

analog604 Posted December 29, 2012 Author Report Share Posted December 29, 2012 Thanks for the replies. Yes the photo is incorrect on the NXP Semiconductors OM13000,598 Mouser listing. The PCB package came with a card providing a URL to NXP and featured a coupon code plus logos of NXP, core_red, and Embedded Artists (it's nxp.com but rewrites to this): http://www.lpcware.com/lpcxpresso Thumbnail photos that I made of it: Same in high resolution: http://analogaccess.com/pics_pics/lpc1769BoardPics/ Next week sometime I'll build out the LPC17 core board and test out MIOS32. -Jay Quote Link to comment Share on other sites More sharing options...
kpete Posted December 30, 2012 Report Share Posted December 30, 2012 It looks like you are right Shuriken. The Mouser picture doesn't match the real board. The board that Jay shows is exactly like the one that I am using on my CORE_LPC17 unit. Does this mean that Mouser is selling the same thing under 2 different part numbers and different costs? 924-EA-XPR-003 & 771-OM13000598 Quote Link to comment Share on other sites More sharing options...
analog604 Posted December 30, 2012 Author Report Share Posted December 30, 2012 Interesting, kpete.. thanks for doing a compare. I was hoping that the core module would arrive today to test this out! No worries though, holiday mail being what it is. -Jay Quote Link to comment Share on other sites More sharing options...
analog604 Posted January 13, 2013 Author Report Share Posted January 13, 2013 guys, I built the LPC-17 today and verified that the alternate (less expensive) NXP part works just fine. Bootloader was flashed correctly and then I loaded MIDIbox NG onto it for a quick test. More detailed photos here cheers~ Jay Quote Link to comment Share on other sites More sharing options...
