AM335x Evm WEC7 - How to change RAM 512MB to 256 MB

Hi,

I have changed the RAM from 512 MB to 256 MB , Image is working fine but some CETK tests related to caches are getting failed and also getting exceptions on kernel/coredll while executing simple applications , which has nothing to do with the exceptions, it seems there is some stack corruption occurring  the same behavior observed from simple application to internet explorer even for ping utility throw exception.

are there any steps or document related to RAM changes ?. 

Please suggest

Thanks 

  • Hi Anant,

    To modify RAM your going to need to make changes in config.bib, image_cfg.h to accurately reflect the amount of RAM you now have on board. If you have modified the number of RAM chips used on board then you will need to modify addrtab_cfg.inc.

    Can you be more specific on what modifications you made to your board to decrease the RAM?

    Regards,
