[ECOS] re: Reading flash config value from application

I have uncommented the CHATTER in flash.c and see the read being called in the Redboot, but not in my application when I use the 'CYGACC_CALL_IF_FLASH_CFG_OP2' call. Am I meant to be calling something to load the data from the flash, so it is available to the macro?
