More on MCUXpresso and BCA

[JBM]

I am porting an older application with bootloader functionality to MCUXpresso.  I have read a number of posts here and this on in particular seems to apply:

In the end, it appears that the best way was to modify the linker scripts and, I assume, not use the managed linker script.   Has anybody been able to load the BootloaderConfig at a specific address with the MCUXpresso manageed linker script?

I have already got the flash relocated (I think) to the right address for my bootloader application. Now I would like to figure out how to move the BCA (I've done it by modifying linker scripts) using the managed linker script.

Hi,

I write a document to show you how to allocate the data at specified address. 

Have a great day,

I've already done what is in this document.   Another person wrote a similar document a year or two ago.  My question was, has anybody done with WITHOUT turning off the managed linker script functionality?

Hi,

If you do not turn off managed linker script, you can't modify the ld file. When you modify the ld file without turning off, the modification will not effect.

Have a great day,

In 99.9% you don't need to turn off managed linker scripts, because you can add/change things with the FreeMarker scripts. Turning off managed linker scripts bypasses all the checks of the linker file and should not be done: using the FreeMarker way has worked very well for me.

Thanks Erich, I'll take a look at that.

Not sure, but maybe this helps
