CC3000 + Launchpad - Program will not fit into available memory

Jordan Baczuk

Other Parts Discussed in Thread: MSP430G2553

I have the program working on the launchpad, I'm trying to refactor the code so that I can have it automatically listen to a specific port and wait for data as soon as it is connected to the AP. However, after a little refactoring and creating new functions for the commands, I quickly ran out of room. I've run the optimization assistant and am using the smallest possible file but it is still too large. I'm just wondering if this was known to barely fit on the MSP430G2553 and if there is another way around this problem. Are there some things that can be cut out of the code? I plan on just using smartconfig to connect to an AP, then be able to send packets back and forth on a single UDP. If this is known to be too small, is there another chip/breakout board you recommend for the cc3000 booster pack? Thanks.

Jordan,

There are a number of static configuration options that can be utilized to reduce code/data footprint.

These are discussed in Appendix D of the SYS/BIOS User's Guide.

Here is a link to a recent version of the User's Guide:

Thanks for the link, but I'm not sure what sys/bios is. I don't know if I'm using it, will those commands work in this case? I am using the msp430g2553 launchpad with the basic Wi-Fi application.

Jordan,

I went ahead and moved this thread over to the wi-fi forum in hopes that it will get a faster response there.

The Host Driver is a very tight fit and without optimisations it doesn't fit at all.

Presumably you have looked at the tiny driver compilation option?http://processors.wiki.ti.com/index.php/Tiny_Driver_Support

Presumably this is flash space you have run out of? In GCC there is the option to try and remove uncalled functions, I believe it is --gc-sections. There may be something similar for your compiler. Otherwise you could go in and #if 0 all API functions which you do not need. Some of the nvmem_* functions for example?
