Error during build

Hi,

I got the following error while trying to build my code. I am using "F2802x_Headers_nonBIOS.cmd" as my linker command file. My code has an uninitialised array of size 512. Can somebody help me understand how "F2802x_generic_ram.cmd" comes into picture? Thanks in advance.

Hi Nisha,

Can somebody help me understand how "F2802x_generic_ram.cmd" comes into picture?

The cmd file tells the linker how to place the software into the hardware. Here's more info you can get on cmd files and how to configure them:

So, in your case Array size seems to have exceeded the limits.

Gautam

Hi Gautam,

Does this mean, an array this big cannot be used with C2000? I wish to eventually do a 512 point FFT on this data. Will the RAM size become a constraint for my application?

Thanks

No, that is exactly why flash memory is present. All you've to do is follow this document:

0550.Running from Internal Flash.pdf

Also, for quick implementation I would like you try the same with "flash_f28027" example found here:

Hi Gautam,

Is it safe to write to the flash memory while the code is still in development? I am new to C2000 Launchpad.

Thanks

Offcourse, Nisha :)

No worries... please continue. Personally, I execute all my codes through flash from day 1 of development, this helps me conduct the flash endurance test indirectly.

Gautam
