Statically Reserving Physical Memory
Statically Reserving Physical Memory
Occasionally, it may be necessary to share a common region of physical memory between drivers or between a driver and the OAL (such as between an IST and an ISR). Similar to sharing a memory region for boot arguments between boot loader and kernel, you can reserve a shared memory region for driver communication purposes in the Config.bib file. A standard practice is to use the DRIVER_GLOBALS structure defined in Drv_glob.h, as mentioned in Lesson 1.
