Hello,

I tried to upload programs to the newly acquiered LPC4088. I started with the provisionned program using the 4 leds. While I uploaded the third version of the program (changing time values), the LPC40088 did not restart. I am using WIN 7 64bits and Chrome.

Now, the LED5 is no more green, LEDS 3 & 4 are dimed (blue) and when I write a file to the LPC4088, I have a file named "fail.txt" with "SWD ERROR" in it.

How can I fix this please ?

Thanks for your help.

LED5 is not accessible from the LPC4088, so I assume you mean some other LED. Anyhow, if the LPC4088 program "hang" for some reason and the HDK cannot get in contact with it, just press the user push-button (found near the USB Host connector) while powering the board. That will place the LPC4088 in ISP/bootloader more. After this the HDK should be able to download a new program (binary file) to the LPC4088.

Yes, sorry LED5 turns on if an Xbee is on the board.

Even powering while pressing the user push-button does not change anything while uploading a bin file.

Still hung.

Why do you think the processor is hung? After a power cycle all three HDK LEDs are always on and the Blue LEDs are in "dim" state until the I/Os are properly initialized by the application program. Have you tested downloading the pre-compiled binary? If failing, press the user-button (close to the USB Host connector) while powering the board (or alternatively, while pressing the reset push-button), but do not keep it pressed while using USB drag-n-drop of the pre-compiled binary.

I seems that it is hung because I did not have those two dim blue leds while using it at the begining. Whatever the button used at power up, I cannot transfert binaries to the board. I always get the fail.txt file.

I tried to upload a .BIN from a Mac or a Linux PC (Ubuntu) without any success either

As a start, I would suggest testing downloading from a Windows PC. That is the only platform from where the new HDK from the mbed team has been tested.

I tested the three plateforms. Same results.

Just a note for possible future readers: Problem solved off-line.

Stephane's problem was not related to the platform so it should work on a Mac. We have, however, not tested ourselves since we don't use Mac. The HDK software is developed by the mbed team and also used on other platforms (such as the LPC812 MAX board). I'm sure there would be more reports from users if it didn't work on a Mac

Doesnt work on 10.8.5 here :(

It is sad that HDK doesn't works on MAC OS X... as the LPC1768 do.

Even with bootcamp (ie boot in windows 7 mode), the 4088 is not reconized as an USB Mass Storage, so from impossible to upload any soft.

Can we expect soon the HDK working with Mac OS X platform ?

Best regards.

If someone else succeed with uploading an bin file to this mbed platform with mac os X, please let-us know.

I'm using Maverick OS (ie 10.8.5).

We are working on an updated version of the HDK that will have the same code base as the LPC812 MAX and be just as stable. As soon as testing is completed we will post the updated files along with instructions on how to upload it on the LPC4088 QuickStart Board.

If you would like to test it before it is released then send a private message to us and don't forget to include your email address so that we can send you the files and instructions.

I ve found a way of using mbed boards with Mac OS X 10.9.1 Mavericks.

I own 2xLPC4088 QuickStart Board and 1xLPC812 mbed/Xpresso.

Every time I tempt to connect the 4088 Board on the Mac, I get some troubles. The board appears, disappers, sometimme the system suddenly reboot himself without preventing of that fact...

After long tests, I found a way that works every time with the boards I own.

I use VirtualBox 4.3.6 (https://www.virtualbox.org/) with and version of Windows XP PRO SP3 installed on it.

I will describe how to use the boards through 12 screens capture.

This tutorial implies that virtualbox, with an full windows xp system are installed on your computer and works fine.

-1- Connect the 4088 board to the mac while pressing the button near the Ethernet connector (USER button).

-2- the mbed board appears on the Finder.

-3- Before starting XP with virtualbox you must :

Start virtualbox to access at the usb options of the virtual machine.

You will see some of usb devices you prevliously declared to be used with the virtual machine

Click and the icon with the '+' sign to add an new usb devices to the virtual machine. You will see that you can add the 'MBED CMSIS-DAP[0100]' device

Add it !

If you double click on that device you will see some informations about the mbed as serail number and other things.

If you want you can rename the device to get an more explicit name of it (good way of doing if you own as I, several boards)

As the board is still 'attached' to Mac OS X, it will not be usable by the virtual machine (virtual machines doesn't share some devices with the host machine), so from, eject it.

Start the XP machine, the virtual machine will find automatically the mbed board ! And will open a window as any usb disk devices.

If your WinXP is in the window mode (a window over the mac os x system, not in the full view), you can cliqu to the USB Icon of the WinXP window that will show you that the MBED is attached to this virtual machine.

(continues on next psot bacause of 3000 char limit).

(second part of the post).

You can then use the online compiler, or create virtual shared disks between Mac OS X and the XP machiine to share folders you need.

Then you can upload, or write to the mbed your bin files as we like to do !

If you have also installed windows serial drivers on the virtual machine you will also discover the Com port to use with an serial terminal emulator like Putty.

you can then set the Putty to use the correct com port (ie COM3 in my case), because it will be different for each board you add.

As you can see, Putty is working without any trouble with the LPC4088 board with WinXp machine.

I hope this small tutorial can help some of you, if you've got some trouble to use the LPC4088 board with mac OSX.

Best Regards.

Raph

Have there been any developments using a Mac to program the LPC4088 bin file?

Hello,

same problem here. How was the problem solved?

Kind regards, Sören

I use USBHostKeyboard and it works. But in comparison to a KL46Z board sending each character takes 100ms. I cannot find such a delay processing of the queue. What is the difference or how can I speed it up? Thanks, Joerg
