Plain executable file

Hello!

I didn't find options in IDE to generate plain executable files (to upload via UART). Please prompt me, where it is.

Thanks.

Thanks ... I just tested it and it works fine. I'm assuming it doesn't matter what you pass into the -p (processor) argument? I've been supplying lpc1343, but apparently it doesn't really matter. Just curious if I need to provide a different argument for the LPC1114, for example.

Or perhaps I'm just trying to be too smart for my own good ... since after two seconds thought this is really only an issue with the USB-enabled LPC1343. :rolleyes:
If anyone wants to automate the binary conversion and checksum update process, here's a simply blog post on adding the appropriate post-build steps: http://www.microbuilder.eu/Blog/10-01-12/Creating_Valid_LPC1343_Binaries_in_LPCXpresso.aspx

Was this updated in the latest release (and if so what is the command-line utility called)?  I'm trying to create a binary file to deploy via the USB bootloader, but every time I deploy it it clearly isn't working.  It's rather time consuming to have to manually calculate/edit every time.

The utility is called Checksum.exe and should be located in C:\nxp\lpcxpresso_3.1\bin. It has one required argument, the path to the binary file to have the checksum inserted. LPCXpresso V3.1 was released December 15th, 2009.

Hello,

It is possible to generate a .bin file within LPCXpresso today, but it will not have the correct checksum for USB ISP. A command-line program will be distributed with the next version of LPCXpresso (to be released December 15th) which can be set up to post-process the .bin file and add the checksum. In the mean time, it can be done with a .hex editor. Here is a short description of the algorithm which is documented in the LPC1343 User's Manual:

The long integers 0-7 in the binary file must sum to zero. Long int 7 is unused and open for the checksum to be inserted. 2’s complement is pretty standard… I think it is done like so: f[7] = (~(f[0] + f[1] + f[2] + f[3] + f[4] + f[5] + f[6])) + 1;

There are also some related FAQ entries for this on the Code Red LPCXpresso site.

I assume you mean a binary file. This is described in the Getting Started.

You select the .axf file in the Prject Explorer, right-click and select Binary Utilities->Create binary

You can change the options used to create the binary file on the Windows->Preferences, LPCXpresso/Utilites preference page,,,,.
