Evaluation Type: Development Boards & Tools
Did you receive all parts the manufacturer stated would be included in the package?: True
What other parts do you consider comparable to this product?:
What were the biggest problems encountered?: The kit didn't function
First of all, I would like to thank Element14 Community for selecting me as an official Road Tester for NXP LPC8N04 Dev Board. This was the first Road test I was doing with an product from NXP.
I usually don't like NXP as they are so Business minded that they have least community impact (That is purely my perception). They do have a good community but their dev boards are professionally targeted. This one here is an Exception fro that trend. (Maybe they learned something from Freescale's FRDM line of kits after they acquired them)
Coming to the review here are couple of photos of the kit and a reference pic of BC Micro:bit platform.
KIT UNBOXING AND REVIEW
So, here is a Kit Review of the NXP LPC8N04 Dev Board ,
Interestingly I took a snap short of memory map and you can see within a APB peripherals there is a Temp sensor followed by a memory map of RFID/NFC an RTC and finally the 4 KB EEPROM, 8kB SRAM and 32 Kb on-Chip flash
Coming onto the most important part of the review, the problems faced, I am SAD to say that I don't have anything to write as the Board did Not function !! the only thing I was getting was an LED Blink on the LED Matrix which is supposed to be there but nothing beyond that.
Another Issue I think is with the quality of the components used, The CR2032 Coin cell connector was of a really bad quality, and during my first time use only I damaged the locking mechanism of the Debugger section.
Thirdly, The selector switch for the LED Matrix / Speaker / Debugger are based on small 50 Mil Headers and I feel, NXP should give extra jumpers as they tend to loosen out and fall.
In this part I tried the Demo App, Unfortunately neither the iPhone 7 which I have nor the OnePlus 3T of my dad was able to recognise the NFC Connection ?
P.S> I have tested both the devices with standard NTAG213 Stick on tag I had laying around from my previous project and both of them recognised the tag and was able to read the NDEF string on them. (The Android phone was able to write too. )
This was what I was constantly getting on my Mobile.
NOTE :: IPHONE DO SCAN AN NFC TAG AS SHOWN IN THE SCREEN SHORTS BELOW , This is a SONY Bluetooth Headphones scanned on an IPHONE.
So, the Board should also have been detected as it also uses the same Tag Emulation ??
I was not able to download the MCUXpresso IDE initially, it tool couple of E-Mails and Opening a Querry to NXP. But I am glad NXP Respong Quickly, apparently there was some issue with my account and it took about 4-5 days for them to resolve the issue after which I Was able to download the Software.
You do need to download a separate package for the board support, or you can get that during the installation.
I yet have to test the Board with the NXP, but first I am working on debugging on what is the real issue with the board ?
In conclusion this is the first board I have seen with really low clock speeds running an ARM architecture. If you are interested in developing NFC based apps, specially Terminal apps/ accessory look no further. And given that NXP is the best selling NFC IP you can't go wrong.
Also it would have been great if NXP would have provided some Tags to play with as
1. They are cheep
Thanks and Regards
Thanks GS - we take on board all you are saying and will take a new look at the possibility to include getting started guides. FYI, we are working on adding the pin connection info to all our boards, starting…
Thanks for giving us another shot. Its not always easy to stay up with all the innovators out there, but we are making big efforts to make our products accessible to all. Feedback is always welcome…
The LPC8n04 looks really interesting from the perspective that it's a REALLY simple Cortex chip. Great possibilities from a teaching perspective.
While I see that there is a direct download for the MCUXpresso board support package from the NXP site, I can't find a download from within the SDK Builder tool. Will this be fixed in the near future?
I am happy to inform that I got the Board Working.
I did Reflow the IC and did reprogram the board using MCUXPRESSO IDE and it worked. So I am not sure wether it was the Hardware or the Software?? Nonetheless the Kit is Now Working Hurrayyy !!
TO be Honest, I felt NXP is more of a corporate company as they never came forward aiding the Community. Only Once I can remember is when the took Freescale and FRDM boards were available as part of NXP.
So, I was so impressed to see that NXP has finally looked into Maker Community section and is making great progress. In fact After this Road Test disaster (I still have to find some time revisiting the Kit), I was not willing to apply for any NXP roadtest. But the Active Community interaction made me change my mind and I did apply for LPCXpresso 51U68 Dev Board.
I roadtested a NXP board some months ago and really struggled - I turned to the NXP forum but wasn't too lucky in finding the help or the basic explanations I required. As a consequence, my roadtest fell quite flat, but was a truthful account of how awkward I found the board. It was that experience that made me pleased to see you getting some feedback from the manufacturer....albeit a little too late.
Good luck when you get around to trying out the board again, I'm sure any updates from you will be warmly welcomed by all readers.
